T5 Light Spread

+1 to what Steve suggests. Now that you're into LED, better off tweaking the ratio of colours on them for more blue spectrum rather than adding T5 fluorescent lamps, especially if you're wanting to control dimming. Flourescent lighting by it's inherent design was never a good candidate for dimming. Pretty sure there's a spectrum shift if they're not run at the designed voltage/current. Then there's the fact that the spectrum on them changes in a relatively short time regardless, requiring the periodic lamp changes associated with the special T5s made for our hobby. They'll be increasingly more difficult to source as well, since the technology shift to LED is making many manufacturers shift gears away from flourescents.
