I guess I had mine high, near 80% over a 40b, some sps where bleached, I am trying radiate @ 65%

i went from 8 400 watt MH and T5 VHO supplemental actinics to 8 radion pros and my thoughts were 100% cranked! softies, clams, zoes did fine and even a 2 chalices did great but anything else i put in either bleached or browns. after reading this post im dialing down to 75% and see what happens with my corals and with any new corals that are introduced. the radions pack a hell of a punch and they will burn like a laser beam if you keep them too low. my depth is 36 inches and still i think now after reading this it needs to be ramped down and raised to 18 inches. my real issue is that i like a bright tank but i guess its all getting used too. I tried to have VHO T5's with radions just to brighten the tank but the ballasts interfere with the electronics of the radions. T5's and radions for me would be the perfect mix. ill keep you all posted as the tank turns. hmm sounds like a soap opera.

What was the interference causing the Radion to do? I was on the phone with Ecotech and they mentioned that if you disable the programming buttons on the light this fixes the interference issue. I am adding 4 T5s to my gen 1 fixture and I am hoping this wont be a problem.

I still can't get over that 50 people run at 60% or less

Good idea setting up this poll however, it would have been more beneficial to set up 3 or 4 polls for the diff generation/modifications possible with the Radion. The problem is there is a big difference in intensity between what you can run a gen 1 Radion w/no TIR lenses at compared to a pro. Alot of people are running their Pros at 25-30% over SPS tanks which I doubt would render the same results for those people still using Gen 1s. If I upgraded my Gen 1 w/TIR lenses to a pro I would probably cut my intensity in half and go up or down depending on the coral response.
 
Well it's been a week or two after dropping my photo period and my spectrum from 12k max to more like 22k max for only about 3-4hrs. All has been a positive change and the most noticeable change that was nearly instant was the zoas and palys. They exploded since the change. I may turn the Radions max intensity down even more since the sps at the top are still light and my new sps frags on the sand bed are growing well.
 
I'm running 8 Gen 1 radions over a 6'x3'x27" deep tank. Tank is 95% SPS. Lights hit max intensity of 75% with all channels at 100% for a few hours in the middle of the day. I tried bumping it up to 80% in the spring and it took months to recover from the bleaching that took place in some of my SPS, so I have to figure this program is the max light they can handle. I simply cannot grow chalices with this program, they cook to death in a matter of days, and I have huge issues with bleaching on fleshier LPS like open brains. However, my SPS seem to love it. I'm sure there is likely a point where I could make all corals sort of happy, but I don't want to mess with the magic sauce to make the 2 bleached out brains I have happy if it will compromise the many thousands of dollars in SPS that I have less happy.

Here's the program:

Stunning tank can you share with me your file I would like see what it looks like on my tank?

I have two gen 2 units approx 9" above my rimless 120gal. I originally had them at a max intensity of 100%. This resulted in bleaching of most of my sps frags. This is a newer setup as I had relocated all my previous inhabitants and decided to start over with only sps. I now have my radions set to 45% on radiant color. I have it performing a 4 week acclimation to 60%. Hopefully I won't bleach anything else.

Wow 41 votes for less then 50% that's insane. I would have never thought that and to be honest I am very surprised.

Yep, these lights are powerful! I am running Gen1 w/TIR and had to raise them 14" above the water just to get them to 40%. I am considering the new Wide TIR lenses to see what they do.
 
Strangely, mh is bright but wouldnt hurt the sps, but led if u tune the intensity down, it would turn dim. Am I right?
If so, is there a particular light spectrum that cause this?
