I just installed 4 new T8 48" 32W actinic bulbs made by Zoo-Med. Never used these bulbs before but got a great deal at Big Al's. Less than $12 ea. and only $6.95 shipping! I'm using these on a T12 electronic ballast. They are BRIGHT. I can almost light the tank (75g) with just these. They are being used to supplement 2 175W 6500K MH
. Very bright white.
Just thought I'd pass on my first impression of this brand of bulb. I would buy 'em again.
