Chanzon LED Driver 300mA (Constant Current Output) 60V-120V Power Supply

I have a LED panel module that requires >74V to reach the 300mA necessary to get to full brightness (yes, I did check this using a power supply). If a power module cannot reach that (or max out its voltage), it will blink the light. This works fine as I plug it in. It is a little bulkier than I expected, but it fits into the space I have for it. It is impossible to predict its lifespan. Only time will tell (oh well, maybe the LED panel will go first).

Bought for an LED floor lamp with a bad power driver. Works well and easy to connect.

If you don't know what you are doing and you just slap one of these bad boys in place of a broken power supply without knowing what voltage peramiters or current draw you need, it may make your led blink, kill your led, just plain not working, or work for a couple seconds then poop out. If you notice a lot of the one star reviews have a lot of these problems or they are someone actually measuring the output and being mad it's plus or minus 5 or 10 percent(which is common industry standards). It's a very well priced constant current power supply just do the research, take your measurements and make sure you are buying the appropriate size. I have bought six of these transformers and each is working perfectly fine.

This was used to replace a failed LED driver in a LED/ Bluetooth speaker combo overhead light. Worked flawlessly for 2 weeks then died. Awaiting a replacement part~ maybe it was a bad unit. I will update if new unit has longevity.

Before gifting my reliable 2012 Toyota Camry Hybrid XLE to my daughter, I used this LED power supply to augment my 176 VDC power supply to top off the high voltage Hybrid battery on my Camry. The pack was removed and inspected to determine which 7.2 VDC modules were not producing 6500 mAh of charge capacity. Two modules could not be revived to meet that capacity requirement and were replaced. The revived battery pack then produced 104% of its original capacity based on the Prius App.

The description is spot on. I have 120 AC in and I needed 80 VDC out, it powered up my LEDs no problem.

Just flashed the Led lights...

I've been using Chanzon chips, drivers, heat sink mounting pieces for about 3 years now to make my own custom fish tank lighting. I love these! Having the freedom to create my own lighting systems (for about 1/4 the cost) for my tanks has been great. The chips seem to last a long time and I have yet to have a drover give out. Highly recommended!
