The only things I can think of that bother me, as they aren't discussed in detail (are below);
They don't explain the actual chip's blend of colors, or what's exactly used. This below statement from Kessil, is a lame description. and to say it's proprietary and spectral intelligence... blah!
"The A360 features Kessil's new proprietary Kessil Logic™, a unique form of spectral intelligence developed for precise color blending and optimal coral growth"
They do show a graph on their page, but this statement tells me it's not an actual graph of the light. Just a representation. "*Color temperature for reference only, and is not a direct measurement of CCT"
The cooling apparatus of the light isn't discussed in detail.
They don't explain the cooling, nor do they talk about what kind of temps it can handle. For example, mounting it in a canopy... and if temps get too hot, does it shut down like the other models? If so, what's that temp range?
$449 is pretty steep, but in the range of some of the similar wattage lights.
The lights I use for example (are just about a $100 more), are 120W and use 3 color LEDs. However, they are much bigger and aren't able to be "controlled" with a controller.
