Giesemann bulbs have tested well in studies I have read. I can't say they are my favourite Bulb company but they are by no means crap. My only con towards them is the dead spots near the End pins other then that they have worked well for me. I have seen others tanks who have had success with them as well. I only suggested them because they are fairly cheap and easy to come by in canada. Ati and aquascience are probably better choices.

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.
