Al B Posted January 25, 2017 Report Share Posted January 25, 2017 (edited) I'm about to replace two flourescent lights in my kitchen with Soft White LED fixtures. While doing this, I plan to replace the ON/OFF switch with a dimmer switch. My question is, Can a dimmer switch designed for incadescent lighting be used for LED lighting ? My LED's are dimmable.

Stick486 Posted January 25, 2017 Report Share Posted January 25, 2017 (edited) this came up before... saved the link... http://www.ledsmagazine.com/articles/print/volume-9/issue-6/features/understand-triac-dimmer-issues-to-ensure-compatibility-magazine.html With old incandescents you are just reducing the voltage across the element but with LEDs you are lowering the voltage to the electronics which fire the LED. It's like low voltage to your TV or stereo is not good. AIUI.... Edited January 25, 2017 by Stick486 lew 1 Quote Link to comment Share on other sites More sharing options...
Al B Posted January 26, 2017 Author Report Share Posted January 26, 2017 After reading the link, I guess my next question has to be, Has a satisfactory dimmer switch been developed to accomodate the LED's since 2012? Since the LED units indicate they are dimable it would seem that dimmers have been developed. Quote Link to comment Share on other sites More sharing options...
Chips N Dust Posted January 26, 2017 Report Share Posted January 26, 2017 I just did a google search for dimmer switches for LED's and it appears that they do make them. Home Depot was the only site that I look at that. I am sure others places have them too. HARO50 1 Quote Link to comment Share on other sites More sharing options...
Stick486 Posted January 26, 2017 Report Share Posted January 26, 2017 so it's been a while since this topic came up... and yes there are dimmer switches... avoid the BB made in china ... HARO50 1 Quote Link to comment Share on other sites More sharing options...

Plus the fact that a seperate 14-2 wire has to be run to the lighting fixtures from the switch. According to some of the reviews by those who have installed this dimmer, certain other types dimmers will work .

I replaced a couple of dimmers to match my LED's that I put in and I bought a couple at Menards for like $15 each. The key to an LED dimmer is that they have an adjustment screw on the side to tweak to take the flicker out of the light. If you use a regular dimmer the flicker and it will drive you insane.

Fred W. Hargis Jr Posted January 26, 2017 Report Share Posted January 26, 2017 It's really a PITA to figure this stuff out. Our house is loaded with dimmer switches, and I've already replaced quite a few with snap switches. I've found some lamps will work with the existing dimmers (the newer models, like Sylvania "Ultra" series) where the older style lamps would not. the technology is evolving rapidly. That said, I love the LED lights....but it is like being on the "bleeding edge" at the moment. DuckSoup, HARO50 and Cal 3 Quote Link to comment Share on other sites More sharing options...

Anyhow, where are you using the LED's? Do you have any in the ceiliing? Cal Quote Link to comment Share on other sites More sharing options...
DuckSoup Posted January 26, 2017 Report Share Posted January 26, 2017 Al, try looking at an electrical supply house near you, maybe Roberts is nearby They might be able to match something up at a reasonable price. A lot of the new dimmers for LEDs require a second pair of wires for control. New construction requires a neutral at the switch box now, motion sensors need it. Manufacturers now make an MC cable that contains a hot, neutral, ground & a pair of low voltage wires for dimmer control within one jacket, not sure of pricing but if you have to fish a wire down the wall this might be a solution.

Fred W. Hargis Jr Posted January 26, 2017 Report Share Posted January 26, 2017 (edited) Cal, some others have a problem sending me messages as well. I thought John was looking into why (he was one who couldn't send me a message) but it appears to be a system problem, I have some messages I've received so I know they are turned on. Anyway, We have a ton of canned lights in this house and so far I've converted the most used ones to LEDs...these are the interior flood lights (BR 30). I've also converted one exterior floodlight to LED (man, those are really expensive). In our table lamps I've switched them all from CFLs to LEDs. For my shop I bought the tube type LED fixtures after I compared the light from them to some very expensive T5flourescent fixtures. In all cases it appears to my eyes there is more light, though the lumens calculation doesn't say so. In the case of the canned and table lights, the dimmers work as long as I buy the premium bulbs. Our basement had just plain old 100 watt incandescents screwed into those porcelain sockets fixtures. For those I bought the cheapest LED bulbs I could find (about $1 each at Blowes). The replacements were 60 watt equivalent and it still seems like there is more light. At our ;last house I had converted the dining chandelier to all LED (those decorative flame tip candelabra base things) and the dimmer didn't work with them, I switched it a snap switch....I hope to do the same thing in this house once those bulbs become cheaper. Edit in: I just tried to re check the PM settings and now I can't fond them...where is that switch? Edited January 26, 2017 by Fred W.

Popular Post Gene Howe Posted January 26, 2017 Popular Post Report Share Posted January 26, 2017 We swithed to LEDs primarily for their brightness. At our age, mood lighting is wasted on us.

Al B Posted January 26, 2017 Author Report Share Posted January 26, 2017 Thanks everyone for your responses. For starters, I'll install the LED's. I'll check with an electrical supply concerning the dimmer. The HD clerks seem to know less than I do about lighting. p_toad, Fred W.

ChuckJ Posted February 21, 2017 Report Share Posted February 21, 2017 LED dimmers at Home Depot cost $13.50 and up. They wire in just like any regular on/off switch. No extra wires required. You have 1 hot wire coming in and 1 hot wire going out plus ground. I built my house in 2005 with dimmers on almost every light. Canned lights throughout every room. I switched to dimmable CFL's when they came out. Paid a fortune for the new bulbs and they never dimmed very well. Then they came out with LED's and dimmers made just for CFL's and LED's. As I've replaced CFL's with LED's, I've been replacing the dimmers also. The ones I've bought cost $24 and can be used as a single or 3 way switch, since many of my switches are 3 way and I want all the switches to match whether they are 3 way or single pole. In a 3 way situation you only use 1 dimmer and 1 regular switch. p_toad, Al B, HARO50 and 1 other 4 Quote Link to comment Share on other sites More sharing options...
Al B Posted March 3, 2017 Author Report Share Posted March 3, 2017 (edited) I've installed LED lighting in my bedrooms, den, living room, kitchen overhead lights and installed a new chandelier in my dining area. The den is on a conventional dimmer which works fine. I guess I can safely assume the dimmers will work on the new chandelier and all other lighting with the possible exception of the kitchen lights. Since these don't use conventional LED bulbs, I'm not sure what would happen with a dimmer. Since we are accustomed to the incadescent lighting I opted for the soft white bulbs and fixtures to maintain the same color light. To me, the daylight color is brighter but has a cold look.

Cliff Posted April 20, 2017 Report Share Posted April 20, 2017 Fuhgetaboutit The led technology is not standardized. The dimmer technology is not made for led lighting it requires a real load. So if you want to dim a series of LEDs using say a Leutron Dimmer you gotta have at least one incandescent bulb in the circuit. What happens with LEDs is that they don't draw enough voltage to communicate effectively with the dimmer. The result is that they flicker and won't actually shut off. There are lists you can consult where people have matched dimmers and LED bulb manufacturers but it all seems a goose chase to me. So if you want variable LED lighting use an old school Rheostat ( aka Fire Hazard) or install multiple LEDs each series with it's own on / off switch to change the lighting amount. I've learned that LEDs are lousy for any photography and they are lousy for medically necessary tissue examinations. HARO50 1 Quote Link to comment Share on other sites More sharing options...
