60 degree optics goes a long way. Not much spread though look how fast the numbers drop as you move away from center vs the radion.

I'm actually feeling a little underwhelmed at the showing of the Radions. I know they're more even, but they do seem to get blown out of the water in terms of PAR by a whole bunch of other fixtures. For nearly 800 bucks a pop, "is it going to be enough to grow clams on the sand bed (or anything else that I want) in a 24-26" deep tank?" shouldn't even be a question that needs answering with a months long experiments in fish stores and on reef blogs, it should have been obvious from the very first test some reefer did with their at-home meter. I was set on getting 6 of them for my tank until I saw people posting PAR numbers in the low 200s at 12 inches deep. I know people keep saying that might not be as important for LEDs, but we have to evaluate new information within our existing framework until a new framework exists, and according to what we've all been learning for the past several decades, those numbers are really not impressive.

*sigh*, more waiting while other people are the guinea pigs I guess.

Maybe I should abandon my automatic dislike for the Radion (mostly due to it being flogged everywhere so heavily) and fall to my knees.

I'm sure Sanjay helped develop the thing so it must be the best. He was involved with the unbiased flow study paid for by Ecotech recently.

There's no doubt that Ecotech markets their stuff far better than anyone else. It's always being conscious of this that sorta drives me nuts. Ranting aside I do really want to see some actual reefs lit with them.

I hear ya Brett, I haven't seen a lot of tanks online with them, compared to the SOL, and the ones I have seen, didnt really impress me. lol

At least there do seem to be more people jumping on with them so there should be more anecdotal evidence from actual independent sources eventually.

The cost has come down a huge amount compared to the early generations of LED's, so this is a positive step, to me though I still see them as an uneconomical option for larger tanks. There's a way to go in this regard still.

Those new Cree XB economically produced LEDs that were recently announced will hopefully help.

I feel like I need a shower after posting a link to RB.

hehe, that blog is my guilty pleasure. They gave me my idea for the little pico I set up that's turning out to be the most successful small tank I've ever run!

Thanks for posting it Fishoholic!

No problem, I figured it was about time I post something informative and useful
