I'm currently building up some LED lights, and have a couple of questions:
I'm using LED specific optics (clear plastic), however I note people using metallized reflectors here. Is there some efficiency advantage to the reflectors, or are they simply what fits the flashlights you have?
I'm thinking of putting a front perpex flat sheet on my light - at least partially to protect my optics, as it's cheaper and easier to replace this if it gets scratched. Will I suffer from a significant efficiency loss due to the two additional air/perspex interfaces?
