Great lights. I have had these for 6 months now and im easily growing SPS in a 30" deep tank with these. gorgeous colors all around and im not even at 100%.

When first looking at upgrading my lights i was skeptical on which brand i should get but getting the AI Sol was a good buy. Great lights and along with the controller perfect match.

Bought these for my 93 gallon cube. I opted for the Sol blue with black casing... very nice looking and high quality lights! I actually did a ton of research before deciding on these units... and it payed off!

First off... If anyone questions the validity of LED lighting for reef tanks, they are living in the past. These things crank out a TON of beautiful light with very low heat and energy usage.

Now... with a unit like this you get the added benefit of the controller that allows for a nice ramp that is constantly changing - much more natural and allows for many "moods" in the aquarium throughout the day and night. Also gives you a pretty much non-stop viewing cycle as the lower intensity settings won't cause algae problems but still leaves enough light to enjoy the view. Way better than the "All or nothing" settings you get with metal halides. These all create beautiful shimmer or "glitter lines"... really gorgeous light all around.

I would highly recommend the blues over the whites... gives you way more range and mood options in the lighting.

In short... fish love it, corals love it, I love it!

Little background, I've had reef tanks for 5 years now and have used PC's, T-5's, and MH's over the years in tanks ranging from 14 gallon nanos to a 150 gallon mixed reef. My main tank right now is a rimless 75 gallon mixed reef with 3 AI sol whites over it. The two lights on the side are kept perpendicular with the front glass and the middle one is parallel with the front glass, because the overflow is in the middle of the tank. The lights are kept about 14" above the water surface.
I really like these lights, because you can adjust the color to whatever you want, it doesn't cost as much to run them power wise, they are very quiet, you don't have to change light bulbs, and they gradually dim to go off instead of just turning on and off like other lighting does (seems more natural and doesn't scare the fish). The only downside is that you have to be very careful when you first start using them. The lights can easily bleach out your corals. It's a puzzle and you just have to find where different corals do best in your tank and adjust the lighting so all the corals can get used to it. I've had the lights over a mixed reef for about 4 months now and I still have to tinker with the lighting, but not as much as when I first installed them. Most of my corals have great color right now and many have improved dramatically from when I first added them to the tank (some were browned out and bleached before going into the tank).

I convinced my father to get these same lights for his 125 and unfortunately, he's not as good as controlling the lights, actually he really never learned how to, and his corals did suffer because of that. I have started adjusting his lighting for him and his corals are slowly getting their color back.
So as long as you are willing to carefully watch your tank the first few months after adding AI sol's and adjust the lighting based on how the corals look, you'll be very happy with these lights.

I visited a local store to buy some halide replacement bulbs... and curiously enough the AI sol blue was being demonstrated to a customer next to me.... I'm always proud to boast about my light system but this time, I quietly joined the demo, went home got online and snatched a pair from brs.... A 2mns demo is all that is required to convince anyone serious reefer to get this light...

I really like the design of this fixture, I just can't handle the price of LEDS. But compared to other LEDS is is a bargain.

I ordered one of these for my 40gal breeder with the intent of adding another later. Long story short I was surprised to discover that one is all I need.

They are great I have 2 of them on a 75g reef and my corals are loving it.

I've used MH, T5, Compacts and these are by far the best value for the money.
My corals are looking great. My power bill has gone down. I'm setting up another tank and I will have AI SOL Super Blue on it!

I have a 300 gallon sps tank with 12 units, I run these lights at 100% for 5 hours a day. Absolutely love them, sps colors amazing with good growth. I did start off with 9 units but went on to 12 units, most people with sps always warn you about the intensity of the light but if your tank is under 400w metal halide and you start running leds on 20 - 30% intensity I will guarantee your sps will start to take a hit(browning out) you should keep them on the same schedule as the metal halides and have 2-3 hours for ramp up and down(sun raise and sun set) but left them up 5-10 inches where the halide was for a while and slowly lower them down.

These things are perfect. Whoever previously said under these reviews that SPS don't do well under these has other issues than lighting. My SPS, LPS and Softies grow like crazy and have AMAZING color. I would NEVER buy anything else. No heat and amazing colors!!

It took 6 units before i could make 4 of them work properly, not a very good introduction to AI, but they have been working for a few months and My power bill dropped $55 per month every thing seems to be enjoying the new light, did some acro fragging and they skinned over in just a few days. still running less than 50 % .
