They don't have any replacement drivers to sell you?
Hi mates, hoping there is some electrical savvy peoples in here who could help me with changing me led driver
One on the far left is the problem, came up to check and only half the board was lit but if leave it to cool down they come back on but go off again after about 10mins
tried looking for replacement online but nothing comes up matching what is on the driver.
Driver box on far left INPUT 80-130v 695mA
box on the right has INPUT 45-65 695mA
Any advice be great
No emailed them no reply, but im thinking surely there must be something out there that would be able to replace the dodgy driver, just working out the spec to get the right one thats why i was hoping someone on here would be clued up on that
thanks for reply
IDK if they sell just one driver, but you may get lucky or they may know who else to ask. Have you tried Alibaba? Good Luck
Any driver with correct output current and a max voltage that is higher than what you are using will work, post a closeup of the label or the specs to know the amperage and we can help you find a suitable driver. Main concern will be that it fits neatly in the case, or you could go crazy and take the opportunity to remote (move outside of the panel) one or both of your drivers. This will bring temps down of course.
edit: didnt see your text at bottom with some of the details, but what we need is the OUTPUT voltage and current. also, looks like the fans are running off a buck driver, is that correct? like, that box that looks like a mini driver, its connected to one of the big drivers?
Only info on the boxes it what i put at the top, probably the reason why im struggling for anything to come up in google
the pic at the top,
bottom of that line the lights stay on which are being powered by the smaller driver - INPUT 45-65 695mA (powering 20 leds )
top of the line which is being powered by the faulty driver which cuts off after being on for about 10mins - INPUT 80-130v 695mA (powering 40 leds)
and yes the box in the middle just powers the fans and is not connected to anything else
all the leds are 3w and when the box is working total draw power is 123watts
so i was thinking can i work out what the output would need to be ? also the input part might not be related to the numbers just displaying which side the input wires are ?
thank you for help so far much appreciated
i will post more detailed pics of the drivers soon

Something tells me the input is really the output and a Chinese interpreter got it wrong. The input should be 110-220 Volts AC, otherwise it would need some kind of converter in there, right ? The question to me is, is the driver at fault or can it be one of those Zeners or even one of the LEDs messing up the circuit? Personally I wouldn't swap out the driver till I tested the circuits. Got a multimeter? If it blacks out and the driver is supplying power it's probably the circuit.
Reason i think it has to do with this driver is because if leave the led for a couple of hours all the lights come back on but after about 10mins or so all but 20 leds go out, if it was the curcuit i would think they wouldnt come back on at all, and i dont think the info is wrong on them.
Even though there looks nothing wrong with this driver im thinking there has to be there has to be.
got a multimeter going to do some googling on multimetering the board see if can find anything wrong with it.
thank you for the input
looks like a cheap part there must be something out there to replace it
That is better info on the problem. I have seen that issue many times and it isn't a driver issue. Initially you said 1/2 the LEDs wouldn't light up, which made me think there were 2 drivers for the LEDs. After you opened it up it appears to be only 1 driver for the LEDs, so with the problem you have and only having 1 driver, that tells me it is a circuit problem.
I am thinking the issue is a weak solder connection in the circuit, and once the light heats up enough it breaks the circuit, and then when it cools down it comes back on. With a multimeter you should be able to locate and fix the issue with a soldering iron and a little flux. Good part, you shouldn't need to have to order a new power supply and can fix it in a few minutes yourself, bad part is it takes a little more work than swapping a driver. I would run the light until it turns off and then quickly run a continuity test between LEDs to see where the break is. That seems like the most simple way to locate the problem if it is an open circuit issue.
That last post it close up of the box on the far left, the box on the far right is exactly the same just different spec and smaller. is this not a driver also ?
