They look pretty good for smaller size tanks. They are still too close to a 1:1 blue to white ratio. And with that ratio there is little or no need for red or green leds. If the ratio were 3:1 then the red and green could be useful. Other than that, they look well made, good looking and they are using good leds. I really like the way the leds are not behind a glass plate and are spread out over the surface of the fixture. There are a few others like that out there.
My questions are:
How big is the tank you are going to use these over and how many fixtures do you plan to use?
How much do they cost? If the Pro is more than $300, it's too much. There are $320 fixtures out there with 2.0 to 2.5 times as many leds and good built-in controllers. They may not have Cree leds, but you can't run them at 100%, so who really cares?
