LED Lighting Voltage Range

So, I need to replace the stock LED pucks that came with my 2016 33IK - they just run too hot for my liking. Even saw one melt on a demo unit at the dealer!
There are more brands to pick from, but I can't find detailed specs on them. Most importantly, what is the operating voltage for the drivers? They all say 12 volts, but the converter will put out 14.2 volts or more to charge the house battery. Do the LED driver boards have voltage regulation on them? Should I consider putting in voltage regulators to protect the LED drivers? I'm guessing the cheap, non-heatsinked driver boards running with 14.2 volts might be causing the heat issue.
Ideas?

Particularly in the 2010 to 2015 era, many of the 12V drivers for LEDs did NOT a good job of handling 14V that are commonly put out by alternators and converters. The drivers would fry, and the LEDs failed (my 2014 A-frame had this problem).

Driver circuits have improved. Newer LEDs set up with drivers for marine/RV/automotive applications can handle the range of voltages pretty well. LEDs for computers with drivers for tightly regulated 12V power supplies DO NOT survive the voltage range outside of a computer. When buying from E-bay and Amazon you have to be careful which type of driver your LED comes with. Unless the package specifies for automotive use, or gives a voltage range of 11-14.5V or better, I won't buy it.

just my experiences
