O.K. let's cut to the chase. Yes, the ultra brite D'lite (speaking about "white" specifically) is a
huge improvement over previous lites. Certainly bright enough to use outdoors in the daytime, but
why? Just wait to do the trick another time. However, indoors, anytime/anywhere... they are a "go"!
I've had these lites for years and people love this effect. It takes very little skill to use
these things, and since the reactions are always really good, I seem to have a pair in my
pocket...never leave home without them. 8^)
