I myself like VHO
's. Everyone has their own opinion regarding VHO
I have VHO
's myself and couldnt be happier with them, not to mention bulbs are alot cheaper than PC
's. but then again they need to be replaced a little sooner than PC
24"=75watts, 36"=95watts and 48"=110watts.
as far as a ballast goes I have the IceCap 660 and you can run 2 or 4 bulbs at a time. You can also run VHO
's or T5's on this ballast depending on the endcaps you get. I have mine mounted with about 1 1/4" between bulbs.
From what I've heard, T5s last longer and are even cheaper than VHO
's. I'm thinking of trying them myself next bulb change around to see whats best for me.
What ever you choose its better than regular NO
