My experience with LEDs (warning: long, but lots of info)

Folks who use shore power much of the time will also be interested in how the LEDs work when the voltage is up around 13.5. The 48 LED panels I use draw much more current as the voltage rises - and they get hot! Some say more expensive LED lights have built in voltage regulators to eliminate that problem. It would be nice if writeups on specific LEDs could say what the current draw is at 12 V and also at 13.5 V.
