WE HAVE REPLACED OUR LED LIGHTS BUT THEY KEEP IN BURNING OUT AND FLASHING

GEORGE May 08, 2016 09:15PM MDT

we are having trouble with our led lights in our showroom

we replaced / re soldered new led lights into position but they don't seem to last they work for about 3 weeks then they start flashing and then burn out ... we are attaching the new led lights straight to the heat sink.. do we need some sort of insulation between them..????

This behaviour typically indicates that the LEDs are not being adequately cooled. You will find more details about cooling LEDs here:

Be sure that they are mounted to a suitable heatsink and that the double sided thermal tape is applied as demonstrated in this video:
