Hi. I've just joined this forum to ask about a problem with my garage lighting.
My sister gave me an unused JCC ToughLED, JC71504, like this:

I installed the lamp in the roof of my garage and it was lovely and bright.

After a couple of weeks, it stopped working. I've put my meter on the output connectors of the two LED drivers; they both have no voltage.
I had wired the lamp into the same place that the outgoing fluorescent lamp was; that is, teed into the supply to a row of LED spots with a few Halogen spots that I have not yet changed to LED's.
The feed to the garage is common to all my garage equipment and tools, including a 240v air compressor.
I've contacted JCC. They were really of no help and are not able to supply replacement driver units.
1) Is there a problem with the way I've connected the lamp that may have damaged the drivers?
2) If I can get hold of suitable new drivers, are they likely to fail again?

Thanks to anyone who replies to this post.

Have you checked the input voltage to see is it present?

I would also ask what is the input voltage printed on the drivers? Some lights are made to be used on construction sites and as such require a 110v supply, not 240v supply, you may have one of these?
If the drivers have failed I see no reason why you can not buy suitable replacement drivers from elsewhere and change them.

Hi. Thanks for replying.
Yes, I checked that the drivers were getting mains to them, 240v.
This is what is printed on the drivers:
Model LD56W
Input: 200-240v, 50/60Hz, 270mA
Output:1.17A, 40-50v
Lamp power 56W
Non-dimmable

I've not been able to find an exactly specced driver online. Are you able to advise where I might be able to get these?

I'm worried that even if I can get some new drivers they may suffer the same fate as the originals. Have they both failed because of something I've done: maybe having Halogen spots on the same spur, ( I will change them anyway) or even surges from my compressor?

If you are sure it says 40-50V on the power supply, I suggest you try looking for a 48v power supply, I have seen them for less than £20

I'm going to take a punt on these: https://goo.gl/wZ7bCU
