Advice on LED lighting wanted

You guys that are running LED's for daylight (no other lighting types) how do your corals look? Was there a big light shock when you swapped over?

I'd love to go LED but I am not convinced they are any good for daylight. Seems alot of people are burning their corals on RC.

I have heard of it too, But the thing with these LEDs is that a lot of them are equivalent, or brighter then Halides, from what I have read anyways, and I think it all comes down to Light acclimation, I am getting the AI sol super blue, and I plan on running it dimmed for a long long while haha, Cause I'm on t5s and leds now, but its a big change for the corals to get so much light all the sudden! Thats what I think anyways, but I could be wrong

There are several other relatively new players in the LED game worth a look. From what I've read so far the two I've provided links to below, have done extensive research & offer design innovations specific to our hobby rather than simply going with the cool white/blue colour combos offered in first generation fixtures.

Orphek claims to have developed their own very own LED based on several years of research

Kessil is more of a spotlight design, using a high power LED array, rather than the commonly used Cree, Bridgelux etc

I have no personal experience with the Kessil but did some checking & it doesn't appear to be dimmable out of the box. So that would be a con if you're looking for such a feature. The power supply for the light is 24VDC & plugs into a normal wall outlet. If you had a way of providing variable DC power from 24 VDC down, I don't see why it wouldn't dim but not everyone will be willing to give that a try when other units offer dimming feature right out of the box. A handy DIYer could make it happen fairly easily though.
