Finding replacement LED driver

naylorpd · Aug 14, 2019

I have in LED light which has stopped working. It's well-travelled, made in China, bought in Azerbaijan and installed in the UK.

I assume the problem is with the LED driver, picture included. Made by Guo Xin, model GX-F36x1W for which an internet search reveals...nothing!

So how do I find a replacement for this to avoid trashing the (quite expensive) light fitting?
The input voltage is 185-265Vac and output 24-100Vdc at 260mA. The stated load is 8-36W which doesn't quite stack up with the output voltage x current!

Thanks

It’s a constant CURRENT driver. That’s why your calculations don’t work.
You need to find a replacement 260mA constant current LED driver.

Google is your friend. Here’s one

constant current led driver 260ma 6w dc 12 24v

constant current led driver 260ma 6w dc12 24v

as above, but the voltage range of the driver is critical. the replacement must be capable of outputting 24V - 100V. anything less than 100V and the LEDs will probably not work. had exactly same problem , only in my case it was 90V top end. a 60V driver just got a brief flicker from the LEDs.

Hi - as above

. And try eBay as well, as often the transformer OEM will sell direct quite cheaply from China .

It is a waste of time and money to replace something that turns out to not be faulty. Why don't you do some tests with a multimeter to establish where the fault is?
