LED ceiling lights melting lenses

I've had 3 ceiling lights that have the on/off button either fry the wiring up in the ceiling and pop a fuse or melt into the round lenses that snap off the base. The two that melted into the lenses had the circuit board come out of the detents in the base and lay directly on the lenses. The other one got so hot it melted the wire insulation creating a direct short above the light itself. All three instances involve the lights being on for less than an hour.I thought LED's are supposed to run cool and draw less energy?? Measured by a heat gun, mine run over 185 degrees at the circuit board. All Bright Line want's to do is replace the lights at no charge since they say they have a lifetime warranty. I'm kinda scared to leave any light in my fiver on for any length of time. Anyone else have this situation ... I can't believe I'm alone here?

I would think something is wrong with the wiring, I have all led's in camper and at home too and never had a problem. This is the third camper with led lights and no problem. LED lights save energy and most of all battery power

Start by checking your voltage to your lights.

I would doubt it's a wiring issue other than a bad circuit board or fixture. LED's do operate much cooler and save energy, however they are still a 12 volt appliance and if the circuit shorts out it will produce heat. I believe the best action would be to replace the entire fixture this way everything is new.

I 2nd checking the voltage to the fixture.

LEDs themselves operate much cooler than filament bulbs, however the associated drive electronics can run hotter. In addition several manufacturers have used cheap Chinese components that fail. There have been several threads on this and FR will replace them. If you are slightly mechanical, best solution is to have dealer send you replacements and do it yourself as it is an easy fix and avoids a long stay at the dealer.

In the photos you posted, the LED chips are the salmon colored devices. The drive circuits are the ones that show the burn marks.

Yep, (Lumen per Lumen)

LED's are constant current devices and when used in multiples they require driver circuits to equalize brightness and draw. When operated at the high end of their specs they can get warm. But, will most always destroy themselves before they would ever burn anything. I suspect the driver circuit you have is the real problem. AND given that it is getting hot enough in a few minutes to burn things, I highly doubt you are saving any power with that lamp fixture. IE. The LEDS aren't drawing much current but the driver circuit is drawing more than a regular incandescent lamp.... Warranty or not, I would dump those things, they are dangerous.

Jim ... there are over 2 dozen of these things in the ceiling from one end to the other in my 2016 Silverback ... stock installation straight from CC assembly line. They are 12V and nothing else running off 12V has issues. There is no particular run that has issues ... one was in the overhead above the sofa in the rear ... the other two were in the overhead above the bed. I agree about operating on the high end of their specs ... it make the light brighter but generates heat. I've had a lengthy conversation with CC about these and they do say others have had the same problems, but no cure as yet other than sending me new ones. I had replaced the standard 12V bulbs with LED's that fit right in the same light socket/fxture on my SOB's ... they never ran this hot, but didn't have the circuit board either.

ouch! Well as you have found, they have told you and I suspect. The issue IS the fixtures (LED driver circuit). Apparently poorly engineered. I know of no way to resolve easily than to replace the fixtures. I would certainly go after the coach manufacture. (You won't find the Chinese company.) In my non-legal expertise you have a good case. Fire in a coach is not pretty. Best of luck..

I replaced all of my Heligen light with LED's light and I can touch the LED's even after they have been on for hours. there must be something wrong with the manufacture of the LED's. The LED's look like they are bigger than the ones I have. I wonder what the wattage is on each LED in the on the board? If they are high wattage( 5 - 10 watts) they will get hotter and need a bigger heat sink,or they will get hot.
