I put up my Radion Pros and was able to Par them out. Here is my updated Par chart.

Is there any way I can get par readings on my leds ?
That's a LOT of light there. Get your corals some sunscreen![]()
Those are some pretty impressive numbers. How many watts is each fixture putting out at 100% ?
Tis is truly amazing I think halides are going to be a thing of the past. I just purchased a brand new G1 and will be installing the TIR lens on it. I could not afford the pro but after looking at your par readings its going to be more then I would need. A 210 par reading at the bottom of a 29" tank is unbelievable. I don't think I come even close right now with my 400 watt radium with 150 vho and my tank is 30 inches deep. I can't wait to get my fixture this week.....I am so ready to get the colors from my sps that I have been looking for. Thanks for taking the time to post the results and keep the picture res rolling.
Don't go crazy blasting with Par. I found that a 20k 20-100% cycle during the day is my sweet spot for SPS growth and color.
Thanks for the advice , I really need to learn the acclimation of these lights. Do you know of any thread that gets into detail with this?
