Superior Lighting Control
With 10 individual set-points, the built-in controller produces much more realistic dawn-dusk and daylight simulations than non-dimmable fixtures.
Plug & Play
With the built-in controller, there is nothing more to buy.
Superior design and high-end components produce 50% more light than most other equally-sized T5 fixtures. An active cooling system allows bulbs to run at a more optimal temperature, improving both bulb output and bulb life.
Produces up to 50% more light than most other equally sized T5 fixtures, without using more energy.
Clean, Contemporary Design
The slim, silver colored body is lightweight, durable, rust-proof and just 2.1” high. All components including the controller and T5 ballasts are built into the fixture housing with the only item external to the fixture being a single power-cord.
Quiet, Cool Operation

Create your own Hybrid
Reef Brite XHO and Tech LED Strips can easily mount to ATI lighting fixtures letting you create your own custom hybrid lighting fixture. If you are looking for some extra shimmer, we suggest using the Daylight White or 50/50 XHO LED Strips but to bring out corals fluorescence and color we suggest adding an Actinic Blue XHO LED and you won't be disappointed.

Tuning Your New LED Light
Most LED lights will actually put out more light than your corals will actually need and without a PAR Meter to test the overall output, it is really hard to guess if the light is too dim or intense. We highly suggest using a PAR Meter to test the output of your lights at different points throughout your tank that you can use to tune the lights output or know where to put specific corals.
Bulbs are Expensive, but Fixture is Great By SV on 4/4/2020SV would recommend this product to a friendAnyone who chooses a T5 fixture over LED is probably looking for a simple, reliable way to light and provide growth for their reef. The sticker shock of a T5 fixture plus bulbs is less than purchasing 2 or 3 high powered LED fixtures. However, buying six $24 bulbs every year will really make the T5/LED price difference negligible over a 5 year span. Pay more now or later.
This ATI Dimmable Sunpower has worked well. Programming through the small control display is easy enough, although it is a bit clunky. There is no bluetooth, wifi, or anything else that allows the fixture to be programmed or communicate to any smart device or computer. Its pretty dumb - which I prefer. The control display with its small directional buttons is literally a standalone micro-controller that does nothing but dims the bulbs. The bulbs are not individually controllable. There are only two channels, one controls a group of 4 bulbs and the other 2 are on the second channel. This limitation allows for some nominal control over coloration and dawn/dusk intensity when programming while keeping the programming fairly simple. Lastly, the clock on the controller will drift slowly over time, and is not smart enough to know about daylight-savings, so annual or semi-annual clock adjustments may be necessary.
ATI recommends that the bulbs be "burned-in" at 100% power for 50 hours before dimming them using the fixture. I have read elsewhere that only one or two bulbs should be changed out on any T5 fixture every two weeks so as to not shock your corals. So here is the conundrum: How do I burn-in my bulbs at 100% and gradually change out bulbs with only a single fixture? The answer is - you don't. You either have to take the fixture "offline" for 50 hours to burn all six bulbs at 100%, then put the fixture back online with the old bulbs, and then gradually replace the bulbs - OR - you purchase a 2-bulb T5HO retrofit kit so you can burn in new T5 bulbs in your garage, then rotate them in 2 at a time. The retrofit kit was an added expense, but it seemed the simpler and least disruptive way to burn-in the bulbs.
The physical construction of the fixture is great. The fans are quiet. The stainless steel sheetmetal exterior is thin but rigid and makes most of the fixture easy to wipe off. Dust does accumulate in and around the two fans on the top, which is not as easy to clean. The clear acrylic shield that protects the bulbs slides off on the left end of the fixture. This is a bit awkward for my tank since my tank is in a corner with a wall 2 feet to the left. Fortunately I have the fixture hanging from two swinging arms (VESA mounts), so I can move it just enough to the right to remove the shield. Too bad ATI does not offer a right-handed fixture. Perhaps ATI should redesign the controller so it can be mounted on the front or back so the user can mount the fixture in either direction.
My favorite feature is that the fixture only has one power cord, which is sleek for the fixture and tidy in my aquarium cabinet. My old, standard Sunpower had three cords (one for each ballast, one for the fan), which was gangly. Since the dimmable Sunpower has a small controller built in, I recommend that owners plug it into a surge protector, or better yet, a small computer battery backup(UPS) to keep it from getting fried.
I have had the fixture for over two years. So far, so good. (knock on wood). No failed ballasts, fans or controllers. Other than yearly bulb changes, the fixture has been set and forget.
I traded my Hybrid Fixture for this? By 9StickNate on 10/26/20179StickNate would recommend this product to a friendIt sounds crazy right? I had a 36" Aurora that I wasn't totally happy with. I switched to the 6 bulb ATI dimmable sunpower. As soon as I turned it on I thought; (That's impressive! What a bright fixture!) it had a crisp blueness that lit up my whole tank. Then, about 30 seconds later, the other channel turned on (4 additional bulbs). Talk about bright! I was amazed! I get 100 PAR more on this fixture at 10" above the water line; than my Aurora at 100% and 5" from the water line.
I was initially concerned, that when sitting on my low couch; that I would be blinded because your staring at the bulbs. This is not the case. The reflectors surround the bulb and don't redirect the light into my face; unlike my old halide fixture.
This fixture is sweet. There's only 1 chord; which, operated 2 T5 channels and the fan. In regards to the dimming features... I don't use them at all.
There's a reason the SPS gurus like T5's; High PAR and excellent spread.
Go with a different brand By Joe on 6/28/2016Joe wouldn't recommend this product to a friendI have owned this light for just under one year. The light is easy to program and operate, however throughout the year I had several problems. For days at a time one of the channels would night come on (2 bulbs) and I would constantly have to reset the light. Finally, the other channel stopped working completely. Additionally, if you have the light plugged into a circuit with a GFCI breaker it will constantly trip the breaker. Not worth the money, I wish I would have forked out the extra few hundred and gone with an LED option.
Good lighting for Zeovit tank By James Tan on 12/23/2015James Tan would recommend this product to a friendHas been on my zeovit tank for less then 6 months now and i find that sps colored up nicely. gotta love the sleek design. I since stop zeovit and start a conventional mix reef and most of my soft corals like the yellow fiji toadstool did not colored up nicely. So im upgrading to a metal halide fixture soon. Customer service is very slow and painful to reach from the ATI side. That is why i give only 3 stars. Overall, still a good lighting for a zeovit tank(SPS).
