Chanzon LED Driver 600mA (Constant Current Output) 30V-57V (In: 100-240V AC-DC) (10-18)x3W 20W 30W 36W 45W 54W Power Supply 600 mA Lighting Transformer Drivers for High Power 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.

We have a track-style light bar with 6 directional LED lights in our kitchen. It started not working well (it would turn on bright, then go dim within minutes) a few months ago. Finally, we ordered this and swapped out the faulty similar unit in the light set and now it works fine. The only weird thing is that after we flip the wall switch on, it takes a second for it to come on. But then it works perfectly.

Order to replace a LED driver board. found it was within specs and this one worked fantastic

Our Costco (brand unknown) light fixture for our dining room went out after about 8 years of service. I figured it might just be the LED driver, so I ordered a couple that had similar specs to the one it had and tried them out. One didn't work, but this one did. Perfect operation for over a year now, at a fraction of the cost of a new fixture.

Received 50W 850nm LED and mounted it to a 50W sink using TG-7 heat sink compound and used a Noctua NF-A8 fan on a separate feed. Tested this with an adjustable switching regulated power supply set to a max voltage of 18V and max current of 1500mA. LED worked fine (verified with near IR camera). Purchased this supply to assure compatibility with the LED for normal use. On first use, it "killed" the LED which cost nearly double the price of the supply. LED now tests "open" and voltage at the terminals is at 53V!! So much for brand compatibility. I' have several high power visible Chanzon LEDs still working with homemade supplies.

This works well as a replacement for the faulty factory driver, that only lasted a little more than a year. However, it is nearly too large and too tall, so I had to carefully position it and use hot-melt glue (applied similar to a bead of caulk) to secure it to the housing. I also spliced in the circuit board connector making certain that polarity was correct. Then tested performance prior to wiring and mounting it back to it's original position.This is a good value - saved me paying 2-3 times the cost for a new light and satisfaction of recycling rather than adding material to the landfill. The original non-working driver will go to the local e-waste collection site. Hopefully, this replacment will last much longer than the original! I'll report back here if it doesn't last!See photos for specs on the old driver compared to the new driver.

Installed it as a direct replacement, but it didn’t work. Refused was very quick though. Wouldn’t hesitate to order in the future. Cheap Chinese electronics can be hit or miss, I guess mine was just a “miss”.

I bought 3 full spectrum 225 LED grow light panels from Banggood for what I thought was a great deal. It turns out the panels were fine, you can find them here on Amazon. The supplied drivers were junk though. I'm a natural skeptic so I checked over my bargain lights and noticed the supplied drivers were snap together, not a single screw. So I plug them in and get my non contact thermometer. Within 2 minutes they exceeded 180*F. I place the drivers in ceramic pots, as to avoid a fire, and ran them. Inside of 2 weeks all had failed. These Chanzon drivers are great! I matched the specs to my panel and these have been flawless. I took them apart and the construction is very robust. Thick circuit board, large high temp capacitors, very pleased. I haven't measured temps since they barely feel warm to the touch. 3 drivers running 16 hours a day for a few months and flawless performance. As a side note people can't follow instructions. You can only measure operating voltage of a LOADED circuit with a constant current driver.

Replaced in our light….Saved a lot of money instead of replacing light!

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.

My 2nd purchase to replace a LED driver rated 30-43VDC 600ma.My 1st purchase is still working since installed in 2019.It will be nice if the output wires are connected by cable connectors instead of being soldered. This will facilitate replacing the output wires with DC connectors used by the original light fixture.

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

Perfect replacement for a Robus wall light over 20 years old and no longer available. Back working perfect again.
