Chanzon LED Driver 300mA (Constant Current Output) 36V-66V (Input 100-240V AC-DC) (12-20) x1W 12W 15W 18W 20W Power Supply 300 mA Lighting Transformer Drivers for High Power COB Chips (PCB Board)

Purchased some lights from a company, and within 2 weeks the driver stopped working. So I matched the drivers specs with this one, soldered it in and now the lights work fine. I would have sent the lights back to the company but they offered to send me a whole new light without sending the original. Now I have 2 lights, but, I suspect the driver will go out in the new lights. When that happens, I'll be ordering another one of these. Easy to use, board indicates what wire is what, for easy solder.

Shop lamp needed a power supply with a lower minimum output voltage than this supply could handle.Vendor was extremely nice and the return was pleasant and easy via Amazon Prime.Vendor is highly reccommended!

The power supply board that drives my LED vanity mirror was overheated, causing the LED to flicker ON/OFF. So I replaced the bad board with the Chanzon LED Driver board, everything works, no flickering LED. Only minor issue is that the transformer on the board emitted a tiny buzzing sound when under load. Buzzing was very low so this didn't bother me at all.

This was meant to replace a failed power supply on My GVSL450HH grow light. I'm having to make an educated guess at what voltage and current is needed and then look for something that comes reasonably close.So I don't know if I've done the math wrong or what. However, this power supply could not even dimly light the LEDs. The LEDs are arranged in series, so I can vary the voltage required by attempting to drive fewer leds. I went from trying to Power something like 40 LEDs down to about 12 and they just barely started to flicker then. I'm not sure that the advertised voltage and current specs were true. But I also can't be certain that it matched the requirements of my LED strips anyway.I have tested the LEDs one at a time and I'm pretty confident that the LEDs are fine.

Connected to 12v 2w 2 led lights, after a few minutes, it sparked and burned.Temporary use regular 12v 1amp power supply for my lights.Still looking for another brand.

Works well in the bathfan fixture I've installed it into(I applied a waterproof coating). Be sure to inspect the wires at the board, as mine had some very minor fraying, and it felt as though even moderate movement would cause more breakage before long.Very happy for the price.

The LED power supply is reliable and a cost effective repair for an expensive light fixture.

Worked good , easy to set up
