Got My Iwasaki 15k 175w MH, Time To Replace T5 Lamps, Anyone better Than Giesmann?

cham · 05/08/2007, 01:56 PM

I've been using URI VHO's because so many SPS reefers love the results of their actinics & I also am using two 11k Giesmann T5's on icecap reflectors for the last year without any complaints.

Does anyone have any links to studies or articles that shows some T5's that produce more or better light? Any personal recommendations?

I think this time since I changed my MH bulbs from 20k to a much whiter Iwasaki 15k I will need to make one of the T5 lamps an actinic.

Suggestions?

Hmmmm. After pluging in these Iwasaki 175w 15k lamps moments ago my plans might have changed a tad.

I am going to need blue, and lots of it. I have a ton of PAR with these MH bulbs, so I am looking at steering towards getting the bluest spectrum I can get my hands on for both VHO & T5.

Any ideas on the bluest of the blue?
