tests done by grim reefer on different bulbs. as you can see the output is horriable. I am just stating on personal experience as well. after finding his tests results it really made sense to me why i was getting slow growth. they aren't the worst but when you have the oppertunity to get something better, why waste your money on them

but i do agree, aquascience are amazing bulbs. i haven't had the oppertunity to try out ati's but personally my favorites are KZ and aquascience

I have 6 ATI Blue+, 3 ATI AquaBlue, 2 ATI ProColor and 1 GE6500K.

1 or 2 of the GE will def bring the result closer to white. The bulb is BRIGHT tho I guess it is more yellow. To my eyes it looks very white.

I think 2 Blue+, 2 AquaBlue, 1 GE 6500K and 1 ProColor would kick butt. 5 of those bulbs I believe test very high for PAR.

This is the par grime listed for Giesemanns bulbs that are of interest.
Midday 325
Aquablue 324

If you look at my configuration that I listed and the first that I suggested for J, you will see i only suggested the G aquablue which has a very high par that matches most other bulbs with a similar K rating. I think the aquablue bulb is by far their best bulb and i was only saying that I had great results with it and don't see any reason not to use it for crisp white color.
