Chanzon LED Driver 900mA (Constant Current Output) 6V-10V (Input 100-240V AC-DC) (2-3)x3 9W 10W Power Supply 900 mA Lighting Transformer Drivers for 10 W High Power COB Light Lamp Bulb (Plastic Case)

Worked as expected

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.

I was a little concerned about the high voltage (43.5V) open circuit as some others have mentioned so I hooked it up to a voltage/current regulator so that it wouldn't blow out my LED. I set the parameters to be a little higher than what the LED is supposed to handle (36V and 1.2A in the 1st image) ...the LED driver is supposed to deliver constant 900mA so I wanted to see if it would max out at 900mA. Sure enough, the current was hovering around 900mA and the voltage dropped to just under 34V which is about the max voltage the LED is rated at. If you have used a variable power supply you know that if you set a fixed current then the voltage would drop once it max out on the current (V=IR).I decided to play around with the different voltage by lowering it to something like 32V ...thinking it would dim the LED but it started blinking. Same thing when I lowered the amp below the 900mA ...LED started blinking. The lower the setting the faster it blinked. I don't think this has anything to do with the LED because when I hooked it up to another variable power supply and lowered the voltage the same LED would slowly dim all the way down to around 22V before going out completely without any blinking. My guess is that if your LED/load does not draw the current that the driver can deliver (900mA in my case) that the driver does something to pulse the output. Usually you can use higher amperage power supply and the device would draw whatever it needed but in this case, buying something with extra mA is not a good thing (like using a 1500mAh for a LED that only draw 900mAh at 34V).In summary, determine how much current your LED needs and buy the matching unit otherwise you might run into issues.

Your LED has to fit the driver parameters. So far it’s working great. The ad description was accurate and the driver arrived in just a few days.

Sticker on front says Brown + blue neutral input but the unit has + stamped on the blue side ? it's the same with the output sticker says Red+ and yellow- but yellow side stamped + I ordered the exact voltage and amp ( current) rating and it was over powering my LED light and made it just blink. So I checked voltage and it was over the listed spec. I hate wasting my time in products that don't work.

I don't know why or razon it's happening. I bought two of those units, but one of them is giving a lot of current and has already blown a couple of LED lights. the other is still fine...Now I got a new replacement and I'll install it today thank you costumer support!!

I like it !

Since the price was just right, I purchased it to replaced my old driver a month ago and it was easy to install.

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.

Perfect replacement transformer for a lamp bought at the Range. Easy to fit and nice and compact. Bought a 12v led driver first and it was not compatible. This transformer has a higher voltage output

Arrived quickly. Good value. The light up quickly. Used in the kitchen, so used all the time. I have used this make of driver for about 6 months and so far they have lasted and performed.

Fast delivery does what its supposed to do

Bought to replace a driver for a high bay light rendered inoperable after flooding. Works fine so far after 1 month. Delivery was a bit tardy but price was good so no complaint
