Do you leave the driver on the lights?

I picked up some used mars sp 250 lights.Do you just leave the driver on?Any issues with it getting too hot in the spot where they live?
Cheers.
 
Yup persinal preference, if you need the extra heat it gots it. If you remove to lower heat only lowers temps a degree or 2.
 
Air gapping just means you put a rubber ring around the screws between light and driver. I'd defo do it if mars didn't do it, those lights aren't known for being well sinked or reliable, every little thing helps. Hotter driver and hotter diodes makes the "fail-ier"

Nothing like an insulator on top of the board to cool those diodes! :wall:

I guess it will keep the housing from burning your hands. :roll:

I leave the drivers on the back but my boards all have heavy finned aluminum heatsinks. Also have sufficient head space.

What thickness of spacer do you recommend?
 
Likely the first thing to fail will be the driver. Keeping it cool by removing it from the LED and maybe even going as far as putting a fan to it could make the light last longer.

A couple of links to show the advertised lifespan of an LED is meaningless.

Drivers aren't cheap either. I would guess that the ones they use on the lower end LED lights like Mars and Spider Farmer will fail even quicker if they are using lower quality equipment.
