These LEDs were advertised as "cool to the touch", but I left them on for about 3 hrs on shore power and they got pretty hot, but you could still touch the metal fixture so I don't think they are a fire hazard.
Wopachop I get what you are saying about higher voltage shortening the service life, but appreciate the use case: This is a truck camper that is used 95% off the grid at battery voltage, not plugged into a CG pedestal. The Honda gen and the solar only charge the batteries during the day, when the lights will be off. I also figured these would be cheap LEDs buying off of Amazon, where do you recommend buying LEDs from?
Schomer, rather than a dimmer you could double the # of LEDs and add a hi/low switch to the fixture, so that you can turn on half or all of the LEDs.
My fluorescents had an SPST rocker swicth on the end:
Replace it with an SPDT:
A lot easier than a dimmer.
