I have read numerous recent posts that discuss lumen losses in real world applications. And it seems that many feel that 35% is a good figure when it comes to losses due to a flashlght's reflector.
Recently I read an article discussing indoor light fixture efficiency and design. The article claimed that newer reflective surfaces in modern light fixtures can reflect up to 96% of the light hitting them. The article mentioned that this allows for many more placement options for interior lighting designers.
The reflective surfaces mentioned were all gloss white, not mirrored.
What I want to know is this:
Are we losing 35% of our lights raw output because of the quality of reflective surface? Should we be experimenting with non-mirrored refectors? Should we try some of these new white reflective surfaces? Are we stuck in old paradigms here?
Or does it have to do with the design of flashlight reflectors themselves (i.e., their shape.)
It sure seems to me that 35% lumen loss is unacceptable for a product that depends on batteries and other off-line power sources.
Can someone explain this all to me? What am I missing here? :shrug:
