If you mix these bulbs in this combination you will have a very hot 11 to 14 K it's a great mix for coral's , coralline's and clam's . Thats what I do for a living is grow corals as fast and healthy as I can thats why we use M/H but we try other things and with T-5 that by the way I think suck to be blunt and VHO do a far better job the only redeeming quality about a T-5 is one can cram more bulbs into a given space.
I really don't like them They are just a smaller bulb with higher pressure gas and that makes them glow a bit brighter to some . I myself would rather run VHO's But Since URI put these bulbs out then to me thats is all that makes a T 5 worth plugging in.. And I ran them side by side with other bulbs . Thats why we have many of the other bulbs still setting up on the racks . Last Nov I was told by our Rep. at Ultra Violet that they where or had a line of P/C bulbs coming out soon .
With any Tube type fluorescent bulbs its all about the Phosphors and they quality of them and the earth metals and the amount of these that make one better then the other.. Its not so much about brightness. _________ Some of the world's greatest feats were accomplished by people not smart enough to know they were impossible (Doug Larson) |
