The power supply that came with my led bar lights wasn't dimmable. This power supply was a cheap way to make them dimmable. Easy to connect and worked great

For those that noted a buzzing sound, I didn’t have this problem when using it in conjunction with a high quality LED dimmer, which i suspect was the issue in others’ reviews. I used this to hardwire a 12v under mount lighting kit. The customer service is outstanding and they walked me through what I needed to ensure a successful installation. Bought 2 more for an additional project for my office!

Product arrived and was easy to install. It arrived with a standard USA 15A 120V domestic outlet plug and a 12V barrel outlet plug with an inline on/off switch as pictured which I didn't need, but they were easy to remove from the PCB terminal blocks and replace with my wiring. Dimming range with a standard LED/CFL compatible dimmer is great and much better than several other products (at significantly higher prices). So far very happy, these are driving 3 banks of LED under cabinet LED puck lights (16 W total load) with good performance.

UPDATE: Now that this has been operating flawlessly for a while, I'm happy to bump the rating to an enthusiastic 5 stars. Also, customer service is great. They contacted me to ask about my experience and why I thought a plug might be useful to some people. I believe they may now offer that as an option.Being the first person to review an item is new for me, since I usually rely on rating averages and numbers before I buy.I decided to take a gamble with this wall-dimmable LED driver, which cost only a third as much as comparable devices. Despite a couple of minor issues, I was overall pleasantly surprised! It work just as advertised with my Lutron CL dimmer to power my high density LED tape strip (warm-white). It provides a full range of dimmability. I replaced their AC power core with my own plug/cable by directly connecting to the dimmer’s AC supply terminals, although wasn’t expecting to have to push on the little tabs to remove the old wires and then release to grab the new wire securely. The blue cover provides a safe strain relief for the power cord.My only complaint is that there could be a bit more documentation (which is why I’m not providing a 5th star). I also suggest providing a standard US power plug, since a lot of potential US purchasers here might not feel comfortable wiring their own plug.
