Time to change my bulbs...Giesemann Megachrome?

[JRod]

I am in the process of changing up my lighting system, removing the VHO's and adding in ATI Aquablue T5 and new 250W SE halides.

Have always run the XM from day 1 so I decided it is time for a change. The bulbs have done me good but when the actinics are off, they look a little yellow to me, want the white and the tint of blue.

So, I have seen the Giesemann Megachrome 14.5K in action and they are crisp white, but I am concerned about the growth I will get off of them. I know PAR is not everything, but looking for some feedback from anyone using them.

Also looking maybe 12K Reeflux.

Running these on 2 IC ballasts and 1 CV ballast.

Decisions, decisions, decisions............

Thanks.

The T5's for supplimentation? you should be getting more than enough light from the 250 MH's.
