I bought one of these on a lark to try it out.

It really works great and it is bright. It will fog paper when put in direct light at several feet, but bounced off of the ceiling it causes no problems, and makes the darkroom liveable. It is bright enough that I can judge prints by without turning on the light. Cheap too.
