Like I’m not gonna get electrocuted or spark something? It’s just really hot in my room, broken window, so I want to turn my ceiling fan on. It broke when I was un screwing a lightbulb a while ago, and its remains are stuck in the light bulb holder thing in the fan. submitted by /u/Rainbow_Slytherin3 to r/NoStupidQuestions [link] [comments]

🚨UPDATE🚨 I tried it again, paired it again, and it worked. 🤷 original post: I've had these styrbar/trådfri lights for some time now. this specific bulb I'm trying out was working beautifully with a lamp just a few weeks ago. I moved and now have this ceiling fan and thought it would be nice if I could use this remote for my main light. I unscrewed the lightbulb that was in it (pictured right) and screwed in the IKEA bulb (left). the light turns on, and does the blinking and dimming in response to the pairing button as if it is paired (as it was not long ago, and has always been), but does not respond to the button for changing the color, dimming, or turning off/on. I went ahead and removed it and noticed it got hot too, so now I'm a bit afraid I'm doing something dangerous lol. I looked for a post about this but couldn't find anything, please feel free to share if someone else had the same kind of problem. I don't know much about how lightbulbs, volts, watts etc work so please explain if I'm doing something wrong, I'd love to learn! and if it's just not compatible, I would love to just know that too, though I would be sad. Thank you!! submitted by /u/crazychristine6 to r/tradfri [link] [comments]

I am looking for help deciding on lighting options for my living room I am remodeling. I am about to install white pine tongue and groove on the ceiling. The slope is fairly steep, I believe it is an 8:12 pitch. Typically we are lamp people and don't prefer overhead lighting, but also I don't know much about design and I figured if we ever sell the house people may find lights installed in the ceiling an appealing feature so I am considering adding lighting while I have it gutted. I am considering 4 can lights, and a ceiling fan without lights. After looking at the super slope can light housings for a traditional e26 bulb, the housings seem really large and I am somewhat concerned with how much insulation they would take out of the ceiling. I have looked into LED low profile cans, such as the screenshot I posted. I'm wondering if this type of light would look good in this room, or if anyone has any suggestions generally about how to light the room. The room is not super big, maybe 250 square feet, and the ceiling is 14 feet at the highest. We like warmer lighting generally but otherwise are open to all ideas. Any help or experience would be much appreciated. submitted by /u/mxw031 to r/Lighting [link] [comments]

I wired a Tuya WiFi ceiling fan in bypass mode so the wall switch acts as a Zigbee event input instead of cutting power to the canopy. The typical: "smart device needs constant power, wall switch keeps killing it" problem. I don't know if you guys have found yourself in the same situation, but truth to be told... The wiring itself is not the hard part. The hard part was figuring out what to even search for!! Because the same trick have a dozen names across HA forums, Zigbee2MQTT, Sonoff docs.... I was getting confused, I did not even know what I was reading... So here a list of terminology I have found. Hardware wiring choice: bypass wiring (HA community) decoupled switch wiring (Z2M's name for the same thing) Firmware feature on the relay: detached relay mode (Sonoff) decoupled mode (Z2M) switch-only mode (Tasmota) They can produce similar end behaviour but they are not the same thing. ...took me embarrassingly long to untangle. So I wrote it all down. Repo has diagrams, vendor PDFs, a parametrised HA automation, and a terminology table at the bottom of the README so the next person doesn't have to go through a similar situation: https://github.com/agigante80/homeassistant-bypass-wiring-fan The project is a Sonoff MINI-ZB2GS in a Spanish switch circuit, driving a Ovlaim DC ceiling fan, but the technique is brand-agnostic and the diagrams are editable Excalidraw. PRs and feedback is more than welcome! :) EDIT: Adding the original reason I set up all of this: Until now, every smart switch I had installed (Sonoff modules behind the wall switch) worked by cutting power to the bulb when the switch was off. That works perfectly for a dumb bulb. Switch off = bulb off, HA can also toggle it remotely, done. But I just installed a ceiling fan with multiple speeds and an integrated light, and the canopy uses a Tuya Wi-Fi smart module for speed and light control. If I'd wired the Sonoff the usual way, every time the wall switch was off, the fan canopy would lose power and drop off Wi-Fi. Technically I could work around it in HA by first turning the Sonoff on, waiting 20-30 seconds for the canopy to boot and reconnect, then sending the actual speed/light command. But that adds 20+ seconds of latency to every interaction (HA automation, voice command, app tap, wall-switch flip alike), which defeats the whole point of having an always-online smart device. So I wired it the other way around. The fan canopy is connected directly to permanent live, completely bypassing the Sonoff's output. It is always powered, always on Wi-Fi, always reachable from HA. The wall switches are not wired to the load at all anymore; their output goes to the Sonoff's S input. The Sonoff just reads the conmutador chain position and reports state changes to HA over Zigbee. The HA automation is simple: when the Sonoff's switch entity changes state (someone flipped a wall switch), check what's on. If the light or fan is on, turn both off. If both are off, turn the light on. That gives the wall switch a sensible default action (light on) while still letting one flip kill everything when the fan is running. End result: Wall switches look and feel completely normal. Fan canopy never loses power, so HA automations fire instantly. Voice control, the HA app, and the wall switch all work in parallel. This pattern is called bypass wiring in the HA community, also known as decoupled switch wiring in the Zigbee2MQTT community, or smart-bulb wiring when applied to bulbs. Same idea: the load gets permanent power, and the wall switch becomes a stateless event source instead of a power cutoff. submitted by /u/Gongshu to r/homeassistant [link] [comments]

So my husband broke the glass dome on our clipsal ceiling fan lights when changing a bulb. He tightened the tension screws too much and cracked the glass. I can't for the life of me find where to get a replacement dome. Everywhere I search incl. the clipsal website has the full light integrated fan for sale but not just the dome as a replacement part. Please help! I know this is a common issue with these types of ceiling lights so I'm sure this should not be this hard to figure out. Anyone now where I can get just the dome? Pic 1 is the light without the dome. Pic 2 is the light with the dome for clarity. submitted by /u/-RosieRosie- to r/AusRenovation [link] [comments]

Thought I would share the following little job I did recently. I got tired of looking for some weirdo non-existent round fluorescent light bulb for my ceiling fan so I bought an LED replacement off Amazon and went to town. I cut out the ballast and replaced it with a dog food can cut to the same height. Enjoy! https://preview.redd.it/w2jyu97cq8zg1.jpg?width=3024&format=pjpg&auto=webp&s=469be86d8a877015170d895b2643b970add4c461 https://preview.redd.it/1h0w997cq8zg1.jpg?width=4032&format=pjpg&auto=webp&s=668fddedaca9399390dacc0c19a41cd1e889c5af https://preview.redd.it/tlyt097cq8zg1.jpg?width=4032&format=pjpg&auto=webp&s=0a6fdc16ddbbc632efc2ab3657c5eda691be0855 https://preview.redd.it/trtkj97cq8zg1.jpg?width=4032&format=pjpg&auto=webp&s=87049034dd59f055bcdf1f57d2fdb865c4bcecd7 https://preview.redd.it/4s0mp97cq8zg1.jpg?width=4032&format=pjpg&auto=webp&s=0fa1cea924f35c7ecadc0f1451f9425f01b46e0f https://preview.redd.it/mp2vr97cq8zg1.jpg?width=4032&format=pjpg&auto=webp&s=548e441054ae63f7362f25ecd844bebd79180d45 https://preview.redd.it/nubyb97cq8zg1.jpg?width=4032&format=pjpg&auto=webp&s=ddfba6a93b01127d4c82e156f9dec2cd67fa181a submitted by /u/TedMittelstaedt to r/DIY [link] [comments]

Hi all. I just got a work-from-home job, so I'm looking to install a ceiling fan in my home office and am looking for some suggestions as to which direction to go. The current ceiling room light has wire run to two switches in a 2 gang box. 1 controlling the light, the other capped off. I'm assuming it was future-wired for a ceiling fan. Here's what I'd like when I'm done: Full control manually, via the two wall switches. Full control via home assistant, regardless of the wall switch states. Smart bulbs in the fan so I can change color temperature at will. Z-wave preferred, Zigbee is ok too. I'm looking at Inovelli products, (A dimmer and a fan switch?) but definitely not locked in. I keep second guessing myself. submitted by /u/upnorth77 to r/homeautomation [link] [comments]

the ceiling fan in my parents guest room has officially reached the sounds like a helicopter trying to land stage. it has been running for over twenty years, and after my last visit, i told them it is finally time to swap it out. this thing is basically a triple threat in the worst way possible. the noise is a constant rattling hum that makes sleeping impossible. the light is just one dim bulb, barely enough to see anything. as for the controls, the pull chain is flimsy and honestly annoying for them to reach. so yeah, my main goal here is something actually quiet, which got me looking into dc motors. also hoping to get a solid built in led so they do not have to rely on random lamps everywhere. after digging around for a bit, i ended up landing on a model from parrot uncle, pic attached. it seems decent overall, clean look, dc motor, plus it comes with a remote which already feels like a big upgrade. now i am a bit stuck on a couple things and figured i would ask here. how tight is the receiver fit inside the ceiling canopy. the junction box is standard, nothing fancy, but i keep hearing these receivers can be annoying to squeeze in. also curious about control options. has anyone managed to pair something like this with a wall switch like lutron caseta, or are you basically stuck with the included remote. my parents are very used to wall switches, so i am trying to keep things simple for them. submitted by /u/autisticalpookie to r/CeilingFans [link] [comments]

So this house was built in 1920 and who knows what kind of wiring is up in the ceiling. I want to install ceiling fans in the bedrooms and living room. I took down one light to check the wiring. Would what looks like lamp cord be safe enough for a modern ceiling fan? I say modern because the newer ones all seem to have LEDs and low wattage motors. I've seen some as low as 47W, which is less than some common light bulbs... submitted by /u/ElG0dDamnDorado to r/AskElectricians [link] [comments]

I'm a new homeowner and purchased a 10-year old home. The week I moved in I switched lots of bulbs from 2700k to 5000k because the house was too dark. Most bulbs were Ecosmart LED so that's what I got for ceiling fans and bathroom vanities. I also got Great value adjustable BR30 for the kitchen and hallway floodlights. Here is the list of issues: ecosmart 60W eq. LED in harbor breeze ceiling fan blinking all the time. Swapped by 40w (also ecosmart) and no flickering, but it's not very bright at all. Tried 40W great value, flickering again. 100w LED g25 in bathroom vanity: constant flickering. swapped to 60w, flickering now and then. swapped to 40w, flickering now and then. In addition, almost every time I turn the exhaust fan OFF in any bathroom, the vanity lights flicker once. Same thing happen if I turn the closet light on in the master bathroom. great value adjustable BR30 are fine in the kitchen but now and then one of them flickers once. those same bulbs flicker for a while in the hallway, but not all the time. I had an electrician come in. He checked outside and inside panels, said the range wire outside was very loose so he tightened it. Said everything was fine and told me to get GE bulbs instead. Those also flickered. I now got philips and tested in the vanity. No flicker so far, not even with the exhaust fan. I spoke with another electrician that said he would probably swap the breakers to see if the problem would go away. I have Eaton type CH breakers. Here is my question: should I just get philips bulbs everywhere or should I keep digging to find the source of this flickering? I don't want to turn a blind eye to a problem that can maximize later but also can't keep spending a lot of $$$ with electricians just to figure out what the issue is. submitted by /u/ActInternational9646 to r/AskElectricians [link] [comments]

So what should be an easy fix has turned into an issue I can't fix. My ceiling light went out, I have spare light bulbs left over by the precious owner. I should be able to just open the light fixture and change the light bulb. When I google reach this image I found videos telling me to turn the center fixture to unscrew it. I tried and can barely get the center fixture to move, I've moved it both clock wise and counter clock wise. I don't know if its just stuck because it hasn't been opened in at least 3 years since I lived there. Any help or guidance would be appreciated. submitted by /u/Gloomy_Depth2718 to r/handyman [link] [comments]

I appreciate this is very simple compared to many posts on here... just sharing in case it helps someone else. I live in a rented flat, as you'd expect; I'm not allowed to change the fittings. I absolutely hate bright lights, so I have soft lighting in most rooms (sidelamps / replaced bulbs in the ceiling pendants etc). The bathroom has a horribly cool-white LED, very bright and offensive to the eyes at night! I took the cover off to see if I could replace the bulb... only to discover it was a built-in LED array. I was happy to discover a switch to change it to warm white (yay)... but it was still too bright. My fix was a £2 silicone air fryer liner from B&M Bargains. I cut slits in the side walls to create fingers that fan out inside the light shade. It creates quite a nice effect and has tempered the brightness to my liking (alternate "fingers" could be removed to increase brightness if needed). Added bonuses are: the silicone is designed to handle heat (the LED produces a surprising amount!) and it's easily removable. submitted by /u/Tooleater to r/DIYUK [link] [comments]

May 11th to December 11th - 7 months of Monstera growth with the help of two grow lights. Many of my plants don't have access to proper natural light from a window. I know the information about grow lights is out there, but until setting them up I think I was greatly underestimating the benefit that good lights can bring to growth rate, as well as the overall boost they give to health and resilience of the plant. I can say that I am now a big fan of purposeful and quality artificial lighting, as it has brought me so much joy seeing my plants thrive. In case it helps someone, here are my notes and personal findings: Starting out I was worried I would fail to achieve a welcoming warm mood in the house with bright grow lights sprinkled around. The gold standard for a beautiful light after some research were those offered by Soltech. However the price was outside my budget, so I looked for alternatives on AliExpress. If you go this route, the key specs that Soltech lights have that you need to find in an alternative bulb are: an LED bulb type, 3000K light temperature (gives that warm cozy feel), CRI above 90 (color rendering index, makes your greens look lush and juicy and covers a wide light spectrum) and a PAR body type (parabolic reflector, focuses the light on the plant in a tight 60degree cone thus improving brightness for the plant while reducing strong side-glare into your eyes when you're in that room). Depending on your plant light needs and distance of the light fixture to the plant, 20-25W is a good bet for a starter bulb. You can go up to 35W or more for light hungry plants, as long as the bulb is not closer than about 2 feet since light burning the plant can be a risk. I'll post a link in comments for a $35 bulb I ordered as an alternative to Soltech ones. I shine two of those bulbs on my Monstera for 12hours a day. You can find lower wattage, different fixture types, but be mindful of the color temperature, different values don't mix well (3000K and 4000K next to each other is noticeable and looks "wrong"). Don't be mislead into thinking that the lower temperature of 3000K is not full spectrum (given the advertising on the 5000K and 6000K lights). It's true that 3000K will be heavier on the warm reds, but it includes the full spectrum needed for photosynthesis. I checked spectrum specs of different LED chips for this. Another alternative that is popular is SANSI bulbs. I tried a few of them. For spaces where you want to maximize aesthetics and cozyness, I don't recommend the SANSI bulb's 4000K temperature and 120degree cone. But if maximizing growth is your main goal, SANSI is the most cost effective option with some decent reliability. I just wish they put a 3000K PAR bulb out. As an easy experiment to gauge how much you need to increase your plant's light, use a light meter app on your phone, measure the sky outside away from the sun as well as into the sun (some plants want indirect light, some want direct) and compare to the light you measure indoors at the leaf level of your plant. The difference is equal to how loud your plant would be screaming for light if it had a sound producing organ. Part of creating a cozy space will be the light fixture you choose. Perhaps one of the bigger lessons I learned is that you cannot commit to a light fixture position for more than 2-3 months as the plant will outgrow it. Over 7 months I "chased" the growth of my plant with 3 different locations on the wall, fully mounted and wired up. A hanging pendant light would probably work best at least until the plant gets close to the ceiling. My final working solution ended up being track lights slightly on the side instead of directly above the plant. Hope this helps someone, I wrote it in a way that would have helped me at the start of my journey into artificial lighting for plants. submitted by /u/Polygon1155 to r/houseplants [link] [comments]

If your going to make a fan smart, make it poperly smart. If not leave it dumb and we will take car of it. Regards P.S. Okay for a harbor breeze fan with temperature light I was able to run a second hot down the center of the fan. That second hot got wired to black (always on) in the switch box. That hot feeds a Shelly dimmer. At 50% brightness matches the warm color of the other bulbs in the room. A lutron caseta fan switch did the rest. The only thing I needed the remote for was to put the fan on high the first time. submitted by /u/cptkl1 to r/homeassistant [link] [comments]

We're buying our first ceiling fans; I'm strongly inclined to get one with standard sockets so we can use standard bulbs, but my spouse doesn't like the kind with the bulbs facing out like shown in the attached image. Any recommended brands that have light socket(s)? https://preview.redd.it/5wmhz0z9xt8d1.png?width=770&format=png&auto=webp&s=e30a26b59158fcfddc00fce92d30a0f46491a9bc submitted by /u/wpirobotbuilder to r/BuyItForLife [link] [comments]

I bought all the ceiling fans in my home from Home Depot. I wanted them all to match throughout the house. I even bought Home Depot's in-house brand because I wanted to make sure I would have easy access to parts should anything happen to one. Well, the time came and one of my fans had the light panel go out (It's a panel of LED lights). I took the light to Home Depot and told them I just needed a new light to replace the one that went out. I had tried looking on the internet for a replacement, but there were only knock-offs that were unclear about whether or not it would work on my fan. The Customer Service agent just started yelling "Rico!" to some guy 50 meters away. Rico came over, took one look without any prompting or opener and said "You have to go through the manufacturer for that part". I told him that's why I was there. Home Depot is the manufacturer. This pissed off Rico. He said "Well there's nothing you can do because we don't sell those." So, I asked "How do I replace a light bulb on a product your company makes?" He said, "You have to buy a new fan". *Cue Malicious Compliance: I said, "Cool, I'll do that, then". So, I bought the new fan. I removed the light panel from it, replaced my light panel, put the old one back in the brand new box, and returned it, telling the customer service agent that Rico said I could return it if it didn't work out for me. She completed the return and I got my light bulb from Home Depot. Fuck you Rico, and the rest of the idiots who made that bad decision at Home Depot. Edit: a word Edit 2: to address a few reoccurring comments. I did tell them I'm returning it due to the light not working. If they sold it after that, that's on them. Rico was rude before I ever said a word. I was as polite as possible through the whole interaction. Rico never changed tone the entire time. Fuck Rico. I have no issue screwing over Home Depot. Even if it's just their name on someone else's product, I don't care. If that's how they want to play, then I will play my way. At this point I haven't seen anything new, so I'm not going to be responding any further. Thanks everyone for my highest rated post! And as always, Fuck Rico, and most importantly, fuck Home Depot. submitted by /u/turboiv to r/MaliciousCompliance [link] [comments]

Finally! This has been several months in the making, and I'm so excited to share it with all of you. Figured this would be useful here, as bright full spectrum light is one of the most important circadian cues. As you’re probably aware, most light sources don’t come very close to mimicking the Sun’s full spectrum of light: The typical LED spectrum has a large blue spike with a dip in the turquoise region, also very little red. Also, it's clear that no single light by itself can easily emulate full-spectrum sunlight. Light, especially bright full spectrum light, is necessary for all kinds of things, not least of which is our circadian-dependent processes like sleep, hormone secretions, and mood. Since many of us spend most of our time inside in our homes or work offices, I wanted to know how close we could get to mimicking natural light indoors. As of right now, I've tested over 100 lights in this endeavor. And since I’ve run out of lights to test, I can now happily share with you the data from those tests as well as my thoughts, findings, and advice on how to go about using this information. Here's the database for your viewing pleasure: Light Bulb Database I also have a write-up post on The Best Full Spectrum Lights if you wanna cut straight to the best! Inside you’ll find some parameters you might not be familiar with, so here’s what I tested for: CRI: This is the Color Rendering Index and compares how well an artificial light source reflects light from 15 color samples when compared with a natural light source. I've calculated my CRI based on all 15 indexes while many only use the first 8. TM-30 Rf/Rg: This is basically a newer version of the CRI standard and uses 99 color samples (this time from actual real-world objects) to calculate a “Fidelity” score with a max of 100, similar to CRI. However, it also gives a “Gamut” score with 100 being identical to the saturation of sunlight, the gamut score can go over or under 100 for this reason. Flicker Metrics: Waveforms, risk graphs and more can be found and the information for these is on the database page as well. I’ve also written a guide on this as well if you’d like to check that out. It contains all the links for the best lights, as well as ideas for implementing light setups of your own. How to Mimic Full Spectrum Sunlight Indoors: The Guide Here are some of my thoughts on the lights I tested: The Shanpu Z0850/55Pro and the GE Sun-Filled bulbs are the best on the market right now. Here’s a comparison of these lights compared with the spectrum of natural sunlight: https://preview.redd.it/pomzef9vzd591.png?width=884&format=png&auto=webp&s=85e5e7be796ef2136614a51fab38ddd7bef783b5 As you can see, the Shanpu Z085o/55Pro is a spectacularly realistic LED. However, it's kind of a pain to buy as 3rd party TaoBao agents aren't super user-friendly. They're also expensive and the lumens per watt is lower than most other LEDs, so you need more of them to achieve a better lux level, which of course just raises the cost more. *sigh* All in, you're looking at something like $600 to put out 10,000 lux from these. However, this is very high-quality light, with no noticeable flicker. If you like paying for the good things in life, this is it! To my knowledge, these are currently THEE LEDs to buy. The cheaper and more accessible alternative is the GE Sun Filled lights. At $8-10 a pop, with higher luminous output, and available on Amazon, they're a great option for someone looking to fill their home with more realistic light. A potential downside is that they do have an invisible flicker a bit in the 120Hz range, which could potentially cause sensitive people issues. I personally use these lights and haven't noticed any negative effects, but that doesn't mean they aren't there. NorbSmile also uses the SunLike diodes in their bulbs, but their offerings cost more than GE and flicker more as well, so I don't really see any reason to purchase their lights. I did email them about the clicker, and they said they'd be looking into it. I was initially very excited about the Sylvania Natural bulbs given the claims and price point, however, I encountered several issues. They’re outright lying about the SPD these give off. The 8w, 11w, and 13w 5000K A19 bulbs all have a generic blue pump phosphor blend SPD, as you can see below. I’ve emailed Sylvania asking for an explanation, and have yet to hear a response. https://preview.redd.it/60mne24a0e591.png?width=884&format=png&auto=webp&s=245b5fe5edb210246a6f3119070833d5b38bbd95 I also measured 16 of the 8w 5000K bulbs and found each one had a flicker rate of 12%. None of the other Sylvania bulbs had flicker, as advertised, so this was unexpected. This shows a pretty severe lack of quality control in my opinion, seeing as how one of the big advertising features of these lights is the low flicker rate and dimming capabilities. I tested several of the leading contenders for the low-blue light bulb market. I think dim, low-blue lights in the evening are important. However, I’m not a fan of red and orange lighting, I find them very unnatural and uncomfortable personally. All the warm low wattage LEDs I tested had insane amounts of flicker, so these were a no-go. The Bedtime Bulb is an interesting product, however, I think they’re too bright for nighttime use, even the lower wattage version, and the custom phosphor spectrum they accomplish isn’t really that special. In the end, the low-wattage incandescent bulbs are the best evening light option in my opinion. The 7w bulbs for example don't exceed 10 lux even at a distance of 2 feet, which is perfect for evening use. My Setup: Alright, I'll end this with my current office setup. I've built two large DIY chandeliers with six GE Sun-Filled bulbs and one 53w halogen each. Though I think I'd like to make another... This gives the room most of its lux. I also have a floor lamp with three halogen BR30s pointing toward me for more full-spectrum infrared exposure, it gives off a pleasant warmth at around two feet. And finally, I have a 48" UV reptile light mounted to the corner of my ceiling molding, spraying the room with a trace amount of UV light. Here's what I've ended up with: https://preview.redd.it/vui9206yzd591.jpg?width=800&format=pjpg&auto=webp&s=3bc3af433d5877e5d47df37fde166c03c6b5d9e7 And here are the spectral graphs from this setup: https://preview.redd.it/exzxycnzzd591.png?width=884&format=png&auto=webp&s=b3a801660bf54c1909645a1cf5b673715e909f1a Here's the info from the UV light output for those interested: 1 ft: 3.5 UVI 2 ft: 1.5 UVI 3 ft: 0.8 UVI 4 ft: 0.5 UVI 5 ft: 0.2 UVI Well, I think that's about it!
