Thanks for your reply. Do you know where the best prices are for them?

Sylvania QTP 1x80T5HO/UNV PSN They only run one bulb each and cost about as much as a 2x54wattT5 ballast (if not more considering you can often find 2x54watters at a discount). Its a sad but true thing about T5 lamps in the US. Its what makes those 80watt Fauna-Marin units such a steal! Too good of a deal I suppose because they are having 'problems' now... and guess what with? Ballast suppliers. Hate to say it, but the IC660 is actually the economical choice when it comes to 80 watt bulbs.
According to Grim though, the performance boost due to the 20% overdrive isnt a full 20% though, so that kinda sucks, but it makes sense. If you look at the wattage per foot ratio of T5s, an 80 watt bulb should be 6' long, so in a way, 5' bulbs are already overdriven at stock, by about 19% (39 and 54 watt bulbs are about 13-13.5 watts per foot, and a 80 watter is 16 watts per foot!). So overdriving the bulbs stock is by 19% (considering at 13ish watts per foot the 5' bulbs should be running at 65watts, not 80), and then add to that the 20% overdrive that the Icecap660 gives... thats a larger boost than the 54watters get when they are running at 80watts! It would seem that the overdriving that the IC660 does in 5' bulbs is beyond the bulb's peak potential, and starting to waste some electricity.

Hey Grim I'm about to set up a 40x26x20H 90g (build thread coming soon) It will not have a canopy, I have a couple of options and keep in mind that i do not mind having a lower light area on the sides for lower light corals. this is a sps dominated tank (transferring current livestock) but i do have some favias and chalices and a tyree leather towards the bottom. I currently run a 250 watt coralvue 20k on a RO1 reflector and i don't really think that is enough. I can pretty much do any of these
6 lamp Tek light 36"
4 lamp ATI fixture 36" (Greg told me about mid march)
1 Lumenmax with a 250 watt or 400 watt MH
a 24" Maristar w/ 1 250 watt DE MH and 2 24" t5's
Those are my options without exceeding my budget which is 400-500.00
Thanks
in advance, by the way I've been following this thread for over a year and have read just about every page but when it comes down to it and it's time to pick your own lights it still a P.I.T.A

If the T5 72" Constellation came with 7 71" 105w bulbs instead of 14 36 watt bulbs that would probably make me go with a pure T5
system. That would be 735 watts vs 546 watts. I emailed an inquiry as to this but no response as of yet from Aquatinics.

Hey Grim, I know or I think I know that you posted PAR ratings for the T5 bulbs, is that in this thread or somewhere else? Thanks.
