I'm thinking about converting a section in my sump to a frag grow out. How do u think this would do as the sole grow out light on a 17" by 17" ? Wanting to grow sps and zoas. I could set the frag rack at whatever depth I wanted. Which color do you think would produce the best results for growth?

Recent PAR for the 10K on a 29 gallon biocube
The LED is 4" from the water, and maxed out the meter at 2888.
Surface was about =2000
Mid tank, 8" from surface =400-500
bottom 15" =80-90
The flashing this thing gave made it hard to settle on a number.
Par readings for the 10K were not on the first page. Frick just posted them on this page, thanks Frick.
Im just north of Denver.
I wonder if the 10k would work in a frag tank to grow out frags faster than under a 400w 20k in the DT?
So good PAR directly under the LED, but not much penetration. Sort of expected I guess for the wide optics and low power. How quick does the PAR drop off to the sides though? Assuming it maintains decent PAR to the sides, looks like it should be a good nano or frag tank light.

I doubt it. The A350 (when released) might have a good chance to compete with a 400w halide.
Yes, there was a bit of drop off on the sides. It is a pretty narrow angled lens. The fixture was really designed for nano tanks in mind.

They are nice. I have been playing with the Ocean Blue (15K) and a Sky Blue (10K). All you have to know is it is the very first LED chip made for aquariums. Everything else was originally designed to do something else and rigged in to an aquarium fixture. The parent company DiCon is very large and makes similair chips for fiber-optic devices. They own the company, the manufacturing, marketing, etc.
This is also the first LED with a glass lense over the 21 diodes, allowing a majority of the usuable UV to get through. The shimmer is like no other LED or aquarium light for that fact. Once you see one in real life you will be hooked.
Took some PAR readings on a 29 Biocube. The 10k topped out at 2888 two inches from the diode. at surface and 6" away it was around 2000. Below the surface about halfway down the tank i got 400, in the sand it was a little over 100. Not bad. The company does not claim to be equivalent to a 150watt halide PAR.
The down side. Yeh... the release date it getting a little drawn out. I was told the end of July.There is only one attachment (the gooseneck) available sold separately and I am not sure if that will be ready the same time as the fixture. It can be hung by eye-hooks tho.
They are not dimmable either. But there is talk of the 350 model being so.

The 15k over my 28 Nano. Looks more blue than it actually is.
It sure WAS posted on the first page.

If it is a 40 breeder then one would be fine but You will get a better spread with two. If it is a 40 long then two for sure.
