Can I use 120ac/12ac transformer for this product? Many other LED pucks seems okay with either dc or ac.

I only tested the puck with DC, but it didn't seem to care about which wire went to which pole. Presumably, if you step 120vAC down to 12vAC, it will function.

Nope, you will need a 120ac/12vdc power supply for these lights. These are light emitting DIODES, so you must observe the proper polarity when you are hooking them up.

There should be no problem.The led is a diode an will rectify the A.C. As long as the voltage stays the same!

If you are using this outdoor, you should absolutely leverage your landscape lights if you have them. Its way easier and cheaper than to use your standard 120V transformer. Your landscape transformer outputs 12V AC. You need 12V DC for the LED. I recommend you get one of these to get the conversion done: 72W Outdoor Waterproof Low Voltage Landscape LED Power Supply Converter/Rectifier, Input 12V AC to Output 12V DCThere's also a YouTube video on how to use it, although it's fairly self-explanatory: https://www.youtube.com/watch?v=OJzarYlOnPc If you are using this outdoor, you should absolutely leverage your landscape lights if you have them.

As long as it physically fits in your fixture, I don't see why not? As mentioned in other responses you will have to deal with our yankee plugs. The response saying that the "ampage" [sic] is too low, seems to have little basis: what you need to worry about is that you stay within the power rating of the transformer. If you are looking at this transformer, I assume your "picture lights" have 12 volt bulbs with a rating less than 75 watts. The fixtures I replaced transformers in have 3 20W 12V bulbs....

This is not an outdoor safe transformer & most LED needs a driver not a transformer, this transformer is for 12v halogen, not LED. Beware of Topstar brand transformers, they are not the best of quality & I bought quite a few from them, most have been replaced with WAC brand lighting transformers.

Probably not a good idea. The transformer that controls the LED's requires a steady voltage input to work correctly. If you reduce it with a dimmer you most likely cause it to work outside its designed parameters. I'm not an electrician so this is just my speculation. Unless it says safe to use with a dimmer in the instructions I wouldn't.

I only used the transformer for initial testing of the light to make sure they worked prior to installing them in my boat. Since the boat is 12 volt I did not need the transformer. I did notice the AC cord did not make a very good connection to the transformer box. I had to wiggle it around and press hard to get the green light to come on. I would check the AC cord is in tight, but most likely the transformer blew.

I would not use this in a home because of 12V. I would purchase a regular home unit made for 110AC.

This is a 120 volt system. You'd need a step down transformer as well as a bulb adapter. If you want LED, buy something designed for it.

These lights are 12 volt DC powered. Your home is wired for 110 AC. You could use a transformer but probably not the best solution for your needs. These lights are hard wired and not plug in. All of the above aside, I am happy with the product and installed 6 of them on my boat.

Ok, just have the original one under my eyes.brand is EVER GLOW.CLASS 2 TRANSFORMERMODEL NO: DCU130060INPUT: 120VAC 60Hz 15WOUTPUT: 13VDC 600mAPS: I used it in France, forgot it could not support 220/230 volts, and it just burnt, so I have to buy another one, but it works perfectly fine in North America.

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 !

You can certainly try, the voltage should work with the light, but you will likely get a 60 Hz flicker that may bother some people because the LEDs will cut off half of the 60 Hz sine wave from the transformer. If you already have the transformer, try it with one bulb; if you're just looking for a way to use 120 VAC, get a AC-DC converter that just puts a rectifier on the output of the transformer: (http://www.amazon.com/Wagan-Amp-12V-Power-Adapter/dp/B000P7O5DG/ref=sr_1_3?ie=UTF8&qid;=1386119232&sr;=8-3&keywords;=120v+ac+to+12v+dc+converter)

I must reconsider my answer after looking at this a little closer. The lights do require 12vDC and not AC. There is such an adapter sold elsewhere on Amazon that can power this string. I would have to say that you probably cannot use this transformer.

I don't care who makes a light bulb. You cannot depend on any hours rating. And this LED bulb is inexpensive and is made by someone who has no name to protect. So even if they rated it for x number of hours, you couldn't trust it. Furthermore, it's an LED bulb...and so the chances are that the transformer will wear out (burn-out) long before the LED fails. You're talking about something that has to be small and yet drop 120 volts down to 4.5 and be able to handle 2-10+ amps in the process. These things runs VERY HOT, which is why the bulbs are heavy relative to size. It's the large metal heat sink meant to keep the transformers from melting. It's the same as for the early CFL bulbs. They were rated for many thousands of hours, but it was generally the step-up transformers that failed long before that.

I wanted the same thing, thinking however I'd switch the halogens out for LED. Didn't like the look and the transformer for some reason would make the lights flash after it got warm. Not entirely sure since I had 10 lights at 4 watts each, for a total of 40 and the transformer is designed for 100 watts. You can "build your own" with other transformers and lights, but that makes it very pricey $$$$ fast. The simple answer is no, you can't go beyond whatever your transformer is rated. It becomes a fire hazard.

they won't work because your transformer has to have some minimal load to work properly, when you installed ONLY led bulbs load of those led bulbs is probably to small so the transformer doesn't work.I Suggest to install 3 of incadescent and 3 of led and then it should work. you can also try 2 of incadescent and 4 led etc.
