Any idea why these lights don't work with the Light Tech LET151 transformer? I strung three sets of lights in parallel. They light up super dim.

These LED lights work on 12V DC. The Light Tech LED151 transformer takes 120V, 60Hz AC and converts it to 12V, 30KHz AC. The key is that the transformer converts AC to AC. The LED lights require DC. Look for a DC "Power Supply" that outputs 12V DC. Each strip will require about 2 amps, so if you want to run 3 strips in parallel, you'll need a power supply that can provide at least 6 amps. This supply might work for you: LE Power Adaptor, Transformers, Power Supply For 12V LED Strip Lights, 6A Max, 72W Max, US Plug

You need to check the amp draw of the light strings and the amp output of the transformer

Wiring 3 sets in parallel is good. However, they operate on 12V DC. The transformer referenced seems to be AC (as indicated by "30 kHz" on the secondary side).

My lighting designer told me that it would not work with low voltage transformers. They suggested the Lutron Diva for that purpose, which is what I am using. I used these everywhere else in my house, though, and they work well. They're a little strange to wire, especially in 3-way and 4-way applications, so you need to have the wiring instructions handy when you're installing them. We also did use these with LED bulbs, and the dimming works funky with dimmable Cree LEDs. One light fixture had two Cree dimmable LED bulbs in it, and the light would not come on when set to a dimming position, when when "turned up" it would flash one of the bulbs on, and then finally the other one. We did not experience this problem with TCP LED halogen replacements, only with Cree standard dimmable LEDs.

Find one with a higher wattage equivalent, they work but not as bright as i would like.I also need to keep one of the original bulbs in the circut. (7) LED & (1) regular filament bulb.If I didn't bulbs would constantly flash. Has to do with Malibu transformer voltage regulator.

You will have to figure out how many amps your lights will draw. Then match that to a transformer

You need to make sure the voltage on your transformer is large enough to handle the bulbs you put in. For example if you use 7 watt bulbs and you have 10 lights, that your transformer is set up for that much wattage total 70 watts.

Sounds like you're trying to use them in a motor home. The input/output specs aren't listed on the fixture so the transformer requirements you'd need are unknown. I've never seen an output this bright coming from a 12 volt source. Good luck.

I switched from the lamps to the LED units and used the old transformer from the initial installation. Obvious much larger than necessary since these LED's are rated at 2 watts. A smaller transformer of 40 watts will work fine with plenty of reserve to add more fixtures.

Well, I am using 4 UltraLED 14W bulbs in one single fixture, and I am using the existing dimmer that I was using before whe I had 4 regular incandescent 60W bulbs. Seems to work fine, except that I can only dim the lights about 40%, after which the bulbs begin to flicker and the go off. Wish I could dim them more. Maybe I should be using a more compatible dimmer.

Some LEDs are not dim-able. Some can be affected by heat such as might build up in a recessed location. Other than that I have no idea. OK, just checked the spec on the switch and this statement is there: "Compatible With 120V, 600 Watt Incandescent Fixture & Load Only (DOES NOT WORK LED LOAD / FIXTURE)". I think this may be your problem.

I put a set on a dimmer and have had no problems without a transformer. Had the lights for several months now.

If you connect the dimmer control between the power source and the splitter or a single light bar it should work just fine. Try both setups to see if the splitter is the problem. If you get only an on/off response or nothing at all with that connection I am sure Lightwiki will quickly replace your dimmer control. Just so you know, my entire system worked great right out of the box and is still working fine. Mike

I did actually did the very same to some degree. I connected only two light strips & it works fine. Can't see why only one strip won't work.The draw [amps] is well under the transformer's limit. If you think about it , if one section goes out. the remaining should still power up. Hope this helps, Edwood

First you have to ask the manufacturer if those are dimmable lights. If so you will have no problem the transformer.

We've been using these lights for about one year and they have been silent. You should check your power source and see the noise is coming from your transformer.

I am assuming you are running this into an Intermatic transformer, right? It works well for me but I Amazon won't let me upload a diagram. If you are following the same diagram I received with the switch and it isn't working I would double check everything and then contact Pentair. Check and see if your transformer powers your low voltage lights without the switch. If so you might have a bad switch. Just to be sure, you do have compatible LED lights, right? The switch does not generate the colors it just makes things easier to select patterns.

If your transformer truly outputs AC you may not want this light. It will try to run on only half of the power half the time because the rest of the time the electricity is going in the wrong direction for this DC device, that will either make it run poorly or not at all. It will also likely shorten it's lifespan. Double check your transformer for output markings if it is an AC transformer with a rectifier that outputs DC then these lights should work fine. Mine have worked well for about a year or so. **Note** They don't like water so if you do use them make sure your fixtures seal.

Mine work wonderfully in a regular light (with adaptor). I don't have and ideas to help, sorry.
