vho lamps

How many VHO lamps can you fit over a 24" wide tank? How wide are the lamps? How wide is the base of the endcap?

Thanks,
Angie

VHO's are T10's so the tube is 10/8" (aka 1.25"). The number following the T tells how many 1/8's of an inch wide they are.

Not sure about the endcaps though.

i have 3 VHO and 24 PC lights on my 55gal/with custom canopy. so i would say you could probably get away with 6 or 8, and that is A LOT of light. my icecap endcaps mounting brackets are 2 1/2" and the bulbs are 1 1/2" wide. i have the URI bulbs, but am getting a coralife VHO 10000k tomarrow. then i will be running 1 10,000k, 1 white actinic, and 1 super blue actinic on the VHO's and 2 50/50 PC's.

I had 4 bulbs on a 65 gallon that was 36x24x18

OK, I guess I " could " get 12 - 72" VHO's (165w each) on a 210G tank. That's 1980w of VHO over that tank. 9.42 watts per gallon ;) a little too much I be thinkin !! (considering I don't want sps or clams) Somehow I don't think that would be better on my electric bill than the 3 - 250w MH's and 2- 60" vho's (110w each) I had on the 125G ..... probably not much cooler temp wise either.

If I ever get this tank going, I don't want the heat issues I had with the MH's. I could always buy a chiller....just don't tell my hubby what a chiller for a 210G tank costs and I may live to tell about it, but I doubt it :)


Thanks for the info.
