LightingWill LED Driver 400 Watts Waterproof IP67 Power Supply Transformer, 90-140V AC to 12V DC Low Voltage Output, Adapter with 3-Prong Plug 3.3 Feet Cable for Outdoor Use, Computer Project

I have purchased this power supply a couple of times for under the cabinet LED light projects. Works great, no problems.

Works great, very happy with it. There are several variants, I have the smallest, the 30 watt. It is set up to run a low voltage light on my flag independent of the rest of the landscape lights. It is small, I was able to put it inside the lightkiwi low voltage box, no problem. In the picture it's tucked in on the left side. Read several reviews that it got too hot and people asking in the questions if it could power things that a low voltage power supply just isn't meant to do.. Let's be real people, it's a low voltage power source, meant for low voltage items. The negative reviews were most likely from people misusing it. If you overload it, yeah it will get hot, yeah it will stop working. I didn't and mine doesn't get hot at at all, crazy right. Use it what it's designed for and you will be happy with it.

Good

Works well. Easy setup.I don't know if this is a design issue but when you turn off the lights it holds an electrical charge that causes the lights to blink at least once after they have been turned off. I know this occurs with other LED strip lighting but it is certainly not universal.

Used 4 of these to replace batteries for my Bali electric blinds. They work perfectly , amp draw for all 4 transformers at rest is only 1 ( one ) watt , pulling up with all four on ..60 watts. One transformer can easily operate two motors. I used four to power 7 motors, with twin tubes of batteries ( 8 each ) .. replaced over 100 batteries that were driving me nuts trying to keep batteries fresh . Very happy with product .. thank you.

Working on a cheaper way to light our house

Since all new landscape bulbs are LED (e.g. low wattage), this unit is great! It would easily power 20 5W lights, for example! Just plug it into a timer and you have a low-cost lighting transformer. If you're replacing an old big black transformer box, just take out those contents and use the box for this... holds this and a timer! Cheers!

If you have other equipment that is sensitive to RFI (radio frequency interference), this power supply will completely disrupt its operation. It's well known that poorly made switching mode power supplies do this, and this one is as cheap as they get, even through its metal case. Unfortunately this power supply renders other sensitive equipment I have, unusable.I have no choice but to donate this to the garbage. Upon looking for a UL Listed or FCC compliance label, I see there is neither and for good reason.
