CHANZONLED Driver 600mA (Constant Current Output) 18V-34V (In: 100-240V AC-DC) (6-10)x3W 18W 20W 21W 24W 27W 30W Power Supply 600 mA Lighting Transformer for High Power 20 W COB Chips (Plastic Case)

I used this to repair an older led pole light. I think they are still being sold here under the name Torchstar.It has a good cast aluminum case that kept water out fine, so I'd like to keep it around. The original driver stopped working, and there were a few individual chips burnt out. Took me a lot of probing and checking to determine the way the leds were in the circuit. No information on the original driver. For this light, it was 75 leds, three parallel branches of 25 leds each. So around 75v drop and 450ma driving the three branches seemed about right. After replacing about four chips last night I hooked it up to the driver and it came on fine and all chips were on. Today I wired everything back into the lamp, cleaned off the old heat transfer paste, put new paste on, and put the repaired panel back into the lamp. I put power back on it, and it came on great again. Then it shut off after a few seconds. Then it came back on for a couple seconds. Then back off. Strobing. Great. I didn't have it on much last night and kicked myself for not just plugging it in for 10 min today to check it before I put it together with the heat transfer paste that is incredibly messy. I thought the new driver was not handling all the leds; and cutting out and back on. Miffed, and wondering about a return or if it was worth checking the voltage on it, I was about ready to chuck the whole thing into scrap metal. I then had another thought. Couldn't be that simple. I held my hand over the light sensor and plugged it back in. The board came on. And stayed on for 5 min. I took my hand off the sensor, a couple seconds later the light shut off. Then a couple seconds after that it came back on again. So DIY'ers, remember that dusk to dawn sensor that you cleaned up and checked weeks ago and made sure it worked? Well as luck would have it, it still works when you wire it back into the circuit. The light was coming on, bouncing around the white walls of my office, and then tripping the light sensor. Then the room, still lit but not bright enough apparently, would be dark enough to turn it back on and start the cycle all over. The driver works fine; fits good in that lamp I mentioned. No idea what kind of longevity it will have. I will probably keep this as a spare. Happy now.

Le produit est tel que j'espérais.Merci très bon produit

Needed one of these to replace a failed unit in a fairly expensive light fitting and it did the job perfectly to the great pleasure of my son's family. Good product, very good price and great delivery. Thanks.

I bought the chandelier and in a few days original led driver burned out. I purchased this LED Driver from Amazon and this device is working great.

I recovered a LED ceiling light fixture. I ordered the driver with the same spec as the original piece. After replacing the broken one. The light fixture is working as a new one.
