Dave, I'm going to put two 150's over my 58. The socket is adjustable from 150 to 250w. they'll work with both.

that's very true, my only queation is that it's for a frag tank and was wondering if the spread would be a factor being that the frag tank is only 15" wide and 20"long and 15" highyou won't get as good a spread as the luminarc.

Shows you the spread differences between the PFO's and the lumenarcs.
according to the analasys, your getting a more even spread of the light with the lumenarc than the PFO.
