Looking to replace an HID

So I've been rolling with 250W MH & HPS, I'm going to have to replace the two bulbs soon. Due to heat issues I'm sick of adjusting for, and someone wanting me to help them with a fluoro set up, I was think of giving it a go. I was thinking of T5's.

I only go with one girl most of the time and two tops. 3x3x6. carbon filter and very adequate fan already in place, would be nice to have fluoros to also run a fan controller to save wattage as well.

Any recommendations for a like wattage swapout? I usually pull almost 2 everytime right now, wouldn't want to dip below a full one with any light loss.

The best fluorescent lights for growing are PL-L's (Power Compact Fluorescent or Biax T5's), there brighter than T5's and cheaper, this is the cheapest price Ive found on a PL-L fixture, its 4 x 55W bulbs (220W total) and its called the "Quad Cuttings & Propagation light 220W", its $112 (70 Euro), (15th item from the top ) (-->CLICK HERE<--) If you have the money to spend and want the brightest PL-L on the market then I would suggest you get a piece of plywood and mount as many of these 96W PL-L fixtures as you need for your grow: (-->CLICK HERE<--) As I said, these are the brightest PL-L's you can get, in the aquarium world they have the nick names, "The Migraine Maker", "The Retina Burner" & "The Beast", with the reflector installed its like looking into a camera flash, there that bright, I imagine about 6 of them mounted to a piece of plywood would be a plant growing machine, especially if you put some on the walls for side lighting.

Unbelievable...over 2 years and this about all the conversation I can find over a BIAX light...a (4 pin level base bulb). I know that they produce a lot of heat but with all the over hype over the over priced LEDs you would figure that the grow community would not lag that far behind the reef tank types. Then again if your into building a full coral reef in a 100+ gallon aquarium you have money to burn. I just bought a track light off ebay that has 2 40W BIAX bulbs (they have mercury so they are more like a long unwound CFL than a T5) that crank out 5500-6000 lumens in a 18x5" fixture that is solid cast aluminum. The aluminum case hopefully will act as a heatsink.
