[rec.aquaria] Ballast technology news

BRIDGE@rcgl1.eng.ohio-state.edu (JOHN BRIDGE) (01/16/90)

As with a lot of TV stuff, high frequency ballasts for flourescent
lights is nothing new. 400 hz ballasts have been around for years
(like 25 years at least). Other frequencies have been in vogue
from time to time. Don't bet on any big breakthrough in this area
however.     John
