For anyone who my be interested....

The 'life-glo' T5 bulbs are triphospher full spectrum bulbs and my be the best overall bulbs made for growing.
T5's have a very poor selection of bulbs, only 3000K or 6000K not much else.

BTW: You can almost double the lumen output by turning your T5 HO into VHO with the substitution of an Ice ballast. (2' 24watt becomes 40watt.)

I'm waiting for a 2' T5 HO reptile bulb, if I could get a few of those I'd do a comparo.
