[Phys-L] Re: LED mini-flashlight price break

Next to the checkout stand at Walgreens they are selling
little LED flashlights for $1.00 apiece. Your choice of
-- red
-- green
-- blue
-- white


These are *not* lasers ... they are not collimated and
they are not monochromatic. But the colors look reasonably
intense.

Could they fool someone into thinking they are lasers? What is the
divergence of the beams? Are they fairly collimated?

Thanks,
Larry
