would this be o.k. for dimming incandescent DC lights on my model train setup? transformer output for accessories is 20volts DC, 8 amps

Well when you dim an incandescent bulb, you decrease the voltage applied to the bulb. A linear Taper Potentiometer will do the job. Dimming an LED is a whole other ball game. With a PWM LED dimmer, the dimmer will actually turn the LED on an off at around 200 hz (faster than the eye can see it flashing). The length of time the LED is off versus when it is on determines how (bright) the LED appears to us to be. Doing this with an incandescent set up may not actually dim the bulb. Incandescent bulbs work by feeding electricity through a small wire that gets hot and glows (which is the light we see). Simply turning that current on and off so many times a second would not dim the glowing wire in the way you wish it would, I suspect.

Yes. I have been looking for the same item and found Leviton 6628 dual slide dimmers which will work on either incandescent or magnetic transformers for LED strip lighting. If you are looking to dim an LED bulb you have installed in an incandescent can light, my experience is that all my incandescent dimmers installed ten years ago, before the advent of LED bulbs for can lights, are working just fine with no ghosting or flicker.

My son's response is that he thinks the transformer changes the current from AC to DC and drops the voltage down. With DC, it will only power a certain number of bulbs before all will start to be dimmer. He thinks that 12 on one transformer would be dim or not work at all. Hope that helps!

The lights state they are DC voltage. This transformer is is AC. They will not work.

I have an electrical engineering degree but have changed career years ago. Unfortunately, technological knowledge has slipped. However, I gave some thought concerning any potential issue if I were to use a low voltage transformer (AC of course) to power these lights. I suppose powering them with with an AC transformer may cause more degradation and shorten the life of the bulbs but other than that, I could not come up with any reason on why they won't work. So, I bought eight to put into my two lamp posts and they seem to work fine with the transformer as a power source. I'm not sure if running the lights with a DC source would produce more lumens but with my transformer, four bulbs in one lamp post still seem dark, definitely not the claimed 75W equivalent (someone already claimed that he measured the power consumed to be less than 5W instead of 9W). However, for my purpose with the lamp posts being decorative, the lumens produced seem adequate as I do have other light sources, if needed. Concerning your question of will they last, I don't expect the degradation to cut the life of the bulb by half but have no data to back up my claim.

Yes the output is 12v dc, I use it for my landscape lighting. I also used another for my ikea halogen lighting. Note they are indoor use only. I had them outside in the cold weather and I got flickering when I dimmed them. When I put them inside the flickering stopped. Great product if you need it to dim lighting at 12 volts dc. Worked for me, hope it works for you. Good luck!

I don't know... what ever you do, you have to make sure you are feeding DC current to the strip of LED's. Since this dimmer is made for AC and not DC curernt, it may not work.

Assuming your lights are 12 VDC and maximum number of fixtures(lights) do not exceed transformer wattage rating, should work fine.

This transformer is 12v AC output. You need DC output for your LED application.

The transformar give you the dirección how to conected, just make sure the power source for the input is 110-120VAC(volt, Alter Current) the out put for this item should be getting 12VDC( volts, Direct Current) if you are connecting an LED make sure your negative and positive are connecting right to make them work other wise just flip the connections.

I did not install it because it is an AC transformer and not suitable for LED lights (which need a DC transformer.) There were no instructions with mine.

Hi ! Before you buy it check the " actual transformer for LED ". Check the voltage and the POWER required . Normally LED strings/strips are working at 12VDC . as I do not know your "LED arrangement" I cannot say if this transformer can be used for your application !

I used a 12 volt 1 amp or greater DC transformer from the Goodwill store ($1.99); works well. LEDs are polarized so you have to get the + and - side correct or it won't work.9 Volts will also work; must be DC.

This transformer just makes 12 volts direct current output. Anything (lights, toys, etc.) that needs 12V DC would work fine on this, although I think this power supply can only deliver 150 watts of power--don't try to draw more than that.

I used: Ledwholesellers inline pwm 12v 2amp dimmer for led strips with DC jack. it works fine for what I need but the connections were a tiny bit looser than I would have liked but otherwise a good product for the price

Hi Nicholas, I can't speak for the switch model you mention, but we are using the Lutron CL Dimmer (Toggler CL) rated at 150 watts for CFL and LED lights (600 watts for incandescent/halogen). Specific model is TGCL-153PH-WH (white). We are using it on the 120v/ac side of the transformer, with 12v Xenon and/or LED lights on the other side, and it works fine. Switch also works well with dimmable 120v LED lights. OOPS - realized this IS NOT an "occupancy" switch - sorry. 'Hope this helps. - Paul

This switch most certainly DOES work for incandescent bulbs. I know this, because it is currently (get it?) working in my incandescent lamp. If your original dimmer was 500W 120V 60H this will work. I'm not an electrical engineer, but I can't think of a single way the switch would know what type of bulb it is outputting power to, which is why I used it, and I couldn't be happier.
