Nope, but I use 575W of MH's and 280W of CF's with excellent results. Have I found a need for 10 tubes? No, but again I don't use them. But if I was to duplicate my setup using T5s, I would need 10-12 tubes. But all this depends upon the size and depth of the growing rack. I illuminate 8 sq/ft at 24" from the light source. Would you say that 2 T5 tubes would be adequate for such a setup? Would 2 tubes even be adequate for a 6 sq/ft at 12" depth that is typical of normal grow racks? If you did, that would certainly blow me away.
This is why I said "you may need." Again, it all depends upon what his setup is as to what he will need. Yet, it appears that the tendency among adopters of T5s is to underscale not overscale their setups. You know, it would be very helpful if you carefully read my posts before commenting, Professor.
-Hermes.
Hermes, you said for a
typical rack... and in the other thread of swords you came back and said that you were talking about a 400 watt
Input fixture when they dont exist or if they do they are not
typical either
I dont know of anyone who uses 10 tubes, much less 12... none
read your post carefully? LOL
How about you stop making wild statements based upon something you've read on the Internet Especially, when you dont have any actual experience with the item in question, Student
Im glad you use MH, nice lights. Ive personally grown plants using T12, T8, T5, MH and LEDs at one time or another, and I have 3 spectrometers that I use to "personally" measure their spectral preformance

Here is 8 sq. ft at 24" + distance
Typical rack, with 6 5000k 85CRI bulbs
Top shelf performance
(last image was taken outside to show the colors were indeed true)
You see Student, I know I'm no expert on lighting but my T5 comments are not based upon something that Ive read online or heard second hand. However, they
are from actual experience and experimentation with the different lighting formats.
