(continued):
then increasing its power.
There's an added benefit to this design: it eliminates the

Part 6. Flashtubes:
Today many strobe manufacturers incorporate a feature that I find
especially useful into their product: the circular flashtube.

distributes light very evenly. It also almost eliminates the need
for a wide angle diffuser, since the light is so widely dispersed.
Many manufacturers also back the flashtube with a dimpled or
coated reflector that softens the
quality of light.
