Loren, are there any LED systems out there that are really white? I've seen
the cheapos that have a distinctly blue tint to them, and don't think I'd
like to read by that. Any websites you've come across that have decent
lighting assemblies ready to put in my 77 Westy to replace the incandescent
over my sink?
Thanks
Courtney
