i had 4 x 250w ushio 20k in de lumenarc mini reflectors. switched to 2 x 400w radium 20k in the large lumenarcs thinking it'd be about the same output with only 2 bulbs covering the whole spread of the tank. boy was i wrong...

IMO The reflector makes the bulb. Is this a hamilton hood or a canopy you're talking about.
Looks great to me! You should be able to squeeze some lumenmax elites or lumenbright mini wides in there.

Well, I've got 11 inches between my Actinics...
Here's another shot that shows both. The hood is 1 foot tall. Would you cut two holes in the top to place the refectors and lights?
Whoops. Didn't get the pic on.

It's a corner tank w/ 3 feet along both back walls and three feet along the front. Then on both sides of the front it bends and goes 10 inches to the back walls. Does that explain it well? I added the other pic of the lights above.
Lumenmax 2 SE pendants would be great if you can squeeze them in??? They are 15" L x 11.5" W x 5" H.
I used one of these over my 36x18x25 LPS softy tank with great success.

wampuscat,
Sorry we took over your thread. If you want I'll split off the help I've been giving puntific into a new thread. Just LMK.

I have 3 250w radiums two on a bluewave 7 and one on a icecap. The icecap seems more crisp and a little less blue. I like both and it would probably come down price if I got anymore. I do run a fan on the bluewave ballast as it to warm with one.

OK.... so why stick with Moguls? How about Galaxy Dual 250 DE with Lumen Max Elite reflectors and XM 20k Bulbs. One answer is that you can't have Radiums with the DE... How do the XMs compare? The shape of the reflector would be a big plus in my hood.

ps. Thanks wampuscat for letting me tag along in your thread. It seemed like a very related issue.

I like IceCap. Doesn't make those 20,000K Radiums look s'dang blue. I had a 20,000K DE Ushio on my old 26, running off an IceCap ballast, and it didn't look nearly as blue as the Radium. At the shop where I worked, it was the standard lighting, with no actinics to try to fake-squeeze-out-colors. ...Except in the display, where there was supplemental actinic VHO (four 4' bulbs), that awful purple fakey actinic, and it looked AWFUL.

all about the diy!!!!!
in this link you can find the proper ballast for the proper bulb.....althou a variety of bulbs will work with different ballast these are straight from ansi and the electrical code on which ballast for which bulb....
