Giesemann has been known for making high-quality light fixtures that use the highest quality parts available, with a durable powder coat finish. Most people will actually call their light fixtures a piece of furniture with how they look. We have run multiple Giesemann lights for years and have been very happy with them. Between Giesemann fixtures and the many other light fixtures out there, just simply the quality of parts and thickness of material make the Giesemann light fixtures our first choice for almost any tank where the light will be mounted externally and be visible.

T5 Lighting has been a proven method of lighting a reef tank that works. For a simple light fixture that is easy to install with either the mounting legs or hanging kit the Matrixx II T5 fixture is an amazing well-built light.
Depending on the number of lamps in the units, the power cords will be able to control different groups of lamps independently. That allows you to set multiple timers or a controller to "ramp" the light up in the morning and down at night. The Matrixx II gives off a beautiful even light with 99.8% reflective reflectors that keep hot spots and shadows from forming and blending all the lamps into one cohesive color illumination.
With active and passive cooling technologies keeping your T5 lamps at the proper temperature for maximum par output and bulb life is taken care of by the Matrixx II fixtures. With a glass panel that seals off the top of the fixture acting as a giant heatsink, while keeping a beautiful aesthetic appeal. The Matrixx II units have a robust heavy duty extruded and formed aluminum alloy for the outer with hand assembly putting them all together. All parts are pre-painted before assembly to keep corrosion from forming and protect your investment.
Giesemann uses high-quality ballasts as they do understand for a slight bit more in ballast cost, the light output is much greater than the standard ballasts the industry uses.

Product Questions
That should be plenty of light for an SPS dominated tank provided you aren't trying to grow super demanding Acros across the entire length as there will be some dimmer areas on the end of the tank.
Based on our tests with the ATI fixture we suggest mounting the light around 6 above the water for minimal light spillage. Due to the fact this light would be a bit shorter than the tank you may want to hang it a bit higher for better coverage.
Hope this helps!
When it comes to T5 fixtures and what lamps to put in them, a lot of it will come down to what do you like to see and what are you trying to grow. For almost all fixtures we do a mix of 2x ATI Blue Plus, 2x ATI Aquablue Specials, 1x ATI Coral Plus, and 1x ATI True Actinic lamps. We find that mixture produces a nice spectrum around 16-18k and allows for good growth of most corals.
Giesemann does have mounting legs available for the Matrixx fixtures. I have included a link below! Feel free to let us know if you have any further questions!
