12V 20W Power Supply Driver TRIAC Dimmable Transformer for LED Flexible Strip Light (Works with Standard Wall Dimmers)

UPDATE: After leaving my original review, I was extremely impressed that the president of the company reached out to me and offered to replace the item. He informed me that there had been some changes to the product and wanted to send me a new one in hopes of remedying my original complaint. Not only did the replacement arrive VERY quickly, it totally did the trick. Not only does the product work perfectly now, I would also been super confident purchasing anything from this company in the future. They really went above and beyond.I'm giving this 2 stars instead of 1 because I actually am able to dim my lights using this device. The buzzing noise was not noticeable at first because there was loud conversation in the room, but when things get quiet there is an insanely loud buzzing noise that will definitely drive you crazy.

I tried 4 other transformer brands - several digital drivers and some analog magnetic low voltage transformers, but they all flickered terribly at lower light levels and even at 50% intensity. This led driver truly surprised me! Zero flicker even at 5% dimmed level and a smooth and crisp transition from low to high. Also, it works with several smart dimmers I tested, including z-wave home automation dimmers such as linear WD500z-1. It seems to me that this company truly got the technology right; being able to transform the dirty/dimmed AC voltage from the dimmer to a clean variable 12v that works perfectly with my LED strips. It's worth noting that it does get pretty hot while operating -- hopefully that doesn't affect longevity.

So far, this power supply is working great and is powering an array of LEDs that I have in my set up. My only complaint is that I found it very difficult to remove the DC wire output wires with the tools that I had on hand. I wanted to insert my own wires into the power supply that I had previously setup but couldn't get the darn power supply screws to loosen to release the wires. You need a very thin screw driver to fit inside to reach the screws and I actually had 3 screw drivers available that fit down there just fine. But I couldn't get any of my screwdrivers to bite onto the screws to turn them. I didn't want to have to buy some specialty screw driver so just ended up cutting the preinstalled plug end off with some wire cutters and stripped them down to splice into my setup. Not the end of the world but just doesn't look as cool as if I could get the wires installed direct into the power supply. But other than that, working great. The dimmer feature works great too and lets the LEDs dim all the way down to a low glow and I'm not seeing any flicker. So working great!

The unit powers 6 under-cabinet lights for the kitchen (LE 10 Pack LED Under Cabinet Lighting). Unit is made in China, feels solid, enough aluminum panels to keep it cool. Easy to disconnect the provided cords, both AC and DC, if you need to hard-wire it as I did.45W/3.75A max: each LED draws 3W/0.25A, so with 6, that's 18W/1.5A, plenty of overhead margin. Probably why the humming is minimal with lights on - it's installed in the attic, I can only hear it when next to it in the attic.Just to mention the very small lag time between switching and lights actually turning on. To be expected with a transformer, I don't even notice it anymore anyway.No flickering nothing, just does its job well so far after 6 months, ~ 1h total daily average usage. Will buy again for my next LED lighting projects.

The ABI dimmable driver works as described, but runs very hot and has a slight buzz. If you're looking to dim with a TRIAC style dimmer, I suggest spending a little more money and getting a magnetic style dimmable driver (I replaced this ABI with model M100L24DCAR). The dimming on the ABI driver was very sensitive on the low end and much less so at the highest light output (imagine a logarithmic curve). With my new magnetic transformer, the dimming is linear and smooth. The ABI driver had a little bit of flicker at the lowest dimming settings (using a Lutron CL Dimmer), but the switch's fine tune adjustment was able to provide a flicker-free setting that was adequate. The ABI driver is good for the price point, but did not work for my kitchen under cabinet lights.

Bought and installed in October. December 23, product failed. Notified the company, any there response was exemplary. My customer is back up any running. I will order this product again.

Product works great with a lutron dimmer except for the buzzing. Seems to buzz more the lower you dim the lights. As others have stated when there is background noise you cant hear it, but in a quiet room it sounds just like a transformer buzzing on a street pole. Hopefully they find a fix for this. I would like to use these in future projects I have planned.

I have some LED cable lights in my office. After a few minutes the fan on the old power supply would come on. Definitely an annoyanceThe silence from this power supply is a delight.I will confirm that the the transformer works with my Insteon Dimmers.And I suggest that a 1 page instruction sheet. That would make accessing the terminals much easier.

Did not require the included jack and plug. Pretty fast start-up. Used to power LED strip light in an older light fixture.
