Just looking to see if anyone has access to this research as I begin.

Which one has the best PAR rating or best rating for growth?

1.CoralVue 14k
2.COralVue 20k
3.Hamilton 14k
4.Phoenix 14k
5.Reeflux 12k
6.Ushio 14k
7.Ushio 20k

from memory it goes like this,

1. ushio 14k
2 pheonix 14k
3 Radium 20k
4 coralvue 14k
8 aquamedic 20k
9 ushio 20k
10 CV 20k

out of all the bulbs mentioned id narrow down to the
Radium, Pheonix, and ushio 20k,

the pheonix is the most blue the ushio 20k the least of those 3, i think the Radium is the best blend, for color and growth..

true but also the ballast you run has alot to do with the color the bulb produces and how much you get outa the bulbs

i just assumed same ballast for all of them, the correct ballast is M-81
