I have used Superbrights in a couple of applications. Their Lights
are not really all that bright and the color is awful. However, they
sell an "anchor" light which I regularly use as a cockpit light
especially when grilling after dark. It is quite bright.

I have also used "sensibulb", LED replacement lights from Sailors'
Solutions. They are quite bright and the color is nearly identical to
incandescent. It is possible to read by the light of the Sensibulb.
They are a bit pricey at $39 per.
