YES YES YES! My initial reaction when I saw them at our auction this year
was "naw, they're just the 'old' T-8's in diameter only," becuase they
donated 36" tubes. But someone (the guy who bought them all!) said
otherwise, so I actually CALLED Zoo-Med to get the scooop. Yes, they're
meant to be run with an electronic T-8 ballast. I think the deal with
running them with a T-12 ballast is that they "sorta" work, but not as
well. I gather the main difference between the ballasts is the current
pumped through the tubes.
> You can get an electronic ballast for around 20 bucks?
Yes. See my other postings, and Ivo's. Go to Home Depot if you can't do
anything else. Go to a commercial place otherwise. But go get one! By
the way, I've found it's only a buck or two different if you get the
four-lamp ballast, so take this into consideration.

They work just as well, if not better, than the IceCap ballasts. They
have something ridiculous like 95% efficiency in the ballast. The
difference, I gather, with the Icecap ballasts is that they can drive all
sorts of lights and combinations, wheras a T-8 ballast is meant to drive
T-8's only. Most of them allow you to use 2-foot, 3-foot or 4-foot lamps,
but check the ballast to be sure.

That's another cool thing about the Zoo-Med bulbs... they have something
like 6 different spectra out there to choose from. Three of them seem
appropriate for planted tanks, and three seem more reef-oriented. They
have the kelvin rating on the box (and probably in the literature).
No, I don't work for Zoo-Med. Didn't even win any of their bulbs
in last club auction OR at the ACA. Just happy to finally start to see
T-8's finally go mainstream and join the ranks of such household
items as SAE's and CO2 injection. :)
