One can. The water keeps the temperature of the foam below its
melting point.

True. However, a gas water heater has to deal with stratification,
where the water is much hotter near the flame than near the tank
outlet. I couldn't determine how much of a temperature difference by
Googling. You're probably correct that it won't melt if it's decent
plastic, but I'm still suspicious. Unless secured to the steel tank,
it might soften, warp, bend, buckle, or otherwise provide an excuse
for water to get to the steel. From there, it's only the anode rod
that protects the steel tank from corrosion.


Yes, I've seen LED flood lights that were plenty bright.
