Cant wait to see the results. Im old school t5 and now that I have the look color wise where I want im super happy. 

I wish I had a T5 unit, and I could have added it to the mix.

I do not have halides,but do have led. My frag tanks are set up with t5. Anyone know how far above the tank i should have the t5's? Tanks are 8 inches deep. 

If you wish to become a supporting member you could borrow the clubs par meter.  The waiting list is only 1 deep right now so it could be to you in a little over a week.  That would be the best way to tell, but I would guess you will be somewhere about a foot above the water.

Found this on Reef2Reef and found it informative on wavelength and intensity of the Hamilton 20k bulb (which I am using) vs the Radium 20k bulb (which I have thought about using). Guess I will stick with the Hamilton. Slightly cheaper, and almost exact wavelength as the more expensive and coveted Radium bulbs.

Can you use a PAR meter to adjust the intensity and placement so the PAR is identical for both LED and MH? Also adjust color on LED so the light is indistinguishable between the MH and LED?

Good idea, I will jump in line for the PAR meter and make the needed adjustments. I think I have matched the color as best as I can tell between the MH and LED... at least to my eye, I will double check with the wife though. She always tells me i'm blind, so I might have to correct it a little. lol

Crimsonvise, what is the timeframe on the above pics? Is this since November 10th? Im getting curious of your par readings myself. On sps i get no change in growth under led, softies are exploding, t5 i get great coloration on all coral but very slow growth across the board. Cant wait to see the settings and par readings.

Correct, this is the growth since November 10th. So about 3 weeks.
