Mounting driver for LED panel

[oldkettle]

Hi

 

I installed 600x600 panel in the kitchen about 5 years ago, the panel, driver and mounting kit came from tlc. Can't recall whether I asked here or just decided myself, but I simply put the driver on top of the panel where it remained all this time - until a week or so ago the panel started flickering.

Quick Google says it's the driver, although I couldn't see any obvious signs of deterioration on capacitors. OK. Ordered a replacement one, the same 50w constant current for 40w panel. The concern is I can see the panel discoloured where the driver was, which makes me want to separate the two a little. Is putting a couple of wooden planks between them acceptable? Any other options? The lead connecting the driver to the panel is very short so moving the driver to the ceiling space is not easy. 

 

Thanks in advance.
