Most (most) LEDs are Dimmable with the correct dimmer switch. Dimming of LEDs and CFLs are based on the electrical cicles used. In other applications, a "CL" Dimmer swithc is used to dim LEDs and CFLs. If one is not used the light can be jumpy and you may have some humming noise.

LED's can be dimmed, and these should be able to be dimmed... but in my application they are either full power or off.

these LEDs are dimmable for most applications. lowest voltage is around 9v assuming these are 1.8v LEDs. a current limiting resistor is soldered onto the boards. the dash light dimmer works for the LEDs and they are much much brighter than the old incandescents. however blue lights are hard on the eyes when using them as a flashlight. use white leds as they don't distort the color of what your looking at.

Hello my friend Walter,Thanks for taking your great interest in our PAR20 light.Yes, this bulb is dimmable. But my friend, no dimmer included. The additional dimmer should be ordered separately.As you know, a incandescent bulb dimmer cannot work for all the LED light while LED light dimer can work for both LED light and incandescent bulbs.If you want, here is the LED dimmer we sell for your reference:Lemonbest® 150W LED Dimmer Switch Brightness Control for Dimmable LED Lights Bulbs, 150W 110VAny question, pls kindly contact Lemonbest freely. We're always here for help.Nice day.Lemonbest Hello my friend Walter,Thanks for taking your great interest in our PAR20 light.Yes, this bulb is dimmable. But my friend, no dimmer included.

dear adam...we use them in the kitchen on a dimmer...the package does not say one way or the other...we have no problems with dimming them....the only drawback is they do burn hot and they burn out rather quickly...paying more for the led bulbs might be more cost effective in the long run....they last a long time and do not burn hot...hope this helps

I think when they are dimmed, yes. Try and return if they don't work for the application. They are MUCH warmer when dimmed than our other LED bulbs. Very pretty.

I am using LED bulbs and am dimming them with the switch. So far, no problems and is working fine...make sure the bulbs state they are, in fact, dimmable.

I am using these with LEDs. Did you hook up neutral and are the lights known to be dimmable? Not all LEDs are...

Dean,These light boards have voltage regulators built in to them so they are designed to be dimmed. The dimming will not harm the LEDs.Thank you for your purchase,Joe Brignolo, Owner, Cabin Bright

NO, mine are in a juno track with juno GU 10 fixtures and have tested using an older incandescent and newer LED dimmer switch; no problems

Not an expert, but I'd say yes and no. They're changing the led light bulbs to work with dimmers, not the other way around. But I do use these dimmers with dimmable Leds, and have had no issues.

Yes, the dimmer switch on my freightliner works the same as always. These are some really bright bulbs, so if you have any incandescent bulbs left in your dash, they will be completely dark before you get to a reasonable low output level for the LED lights.

They can be both, it all depends on your vehicle. In the Dodge Grand Caravan, the lamp housing takes 2 H11s, one is for the low beam, the other for high beam. They are not like H4s, where it has 2 settings within the bulb. The H11s have only 1 filament and is up to one lamp housing to project low & the other project high. Hope this clears it up.

Michael M. I don't know what you are doing but I have several of these and never have an issue. Granted they are not the best quality but no reason for dimmer not to work with them. Do make sure the LED bulbs are dimmable, if they are not you will get a strobe light effect.

It does not work well. They do dim, but not as low as an incandescent. They do flicker if you use only LED bulbs. I had to do the same thing you wrote. I use one incandescent with the LEDs to keep them from flickering. Grrr!

I think you have to use the 31mm size led for that application, (dome light) with out a resistor might mess with your car alarm. Other lights need use a 168/192 wedge bulbs for the map lights. You will have to do more research.

I use these for my map lights. I think I said dome lights in my review, but yes, they work perfect for my map lights. Dome lights are typically a longer horizontal bulb with two archs.

I first tried it with the old dimmer but it flickered a lot when starting up. Also, there wasn't quite as big a range of illumination. I had a new install as well with a LED dimmer and that has a much wider range of illumination--all the way down to barely visible. Using Lutron dimmers that state that they are for LEDs. Good luck, and welcome to the future!

I don't have a dimmer on these bulbs as they are used for landscaping lighting. However, I have a dimmer on some inside LED's and when I bought the dimmer, I noticed that some dimmers said "not" for LED's and some said they were for LED's. I think the digital dimmers are for LED's. It's been awhile since I bought the dimmer, but seems like the ones for LED's were also for dimmable florescent bulbs.
