- 48" Stellar T5 4x54W Hybrid Retrofit Light Fixture - Giesemann
VHO T5 Ballasts | Dual Channel Control | Individual Reflectors
Giesemann Stellar Hybrid T5 Light Fixtures are made to accept many different types of LED lights available on the market today. The simple universal LED mounting bracket lets you incorporate LED lighting technology with the success of T5 lights. If you want to use modular lights like Ecotech Radions, or even strip lights like the Reef Brite LED lights, you can add that shimmer and custom color control to an already proven lighting system. Each Stellar Hybrid light is made of high-quality aluminum with polished individual reflectors for the T5 lights.
- Accepts many different LED modules or strips
- Can add LEDs at any point
- Dual Channel T5 Power Control
- VHO ballasts produce greater PAR and color
One of the biggest challenges with lighting a reef tank can be having enough light available throughout the entire tank, and not just in a few spots throughout the tank. Since traditional LED modules are considered a single point light source they will create spots with super high PAR but when coral starts to grow, shadows will start to appear quickly and can cause your coral's undergrowth to suffer. Using a strip style light like a T5 fluorescent lets you blanket the area with light, ensuring that all of the undergrowth gets proper light to grow while providing the color rendition you like to see with the LEDs and all the other technological benefits.
LED Mounting Brackets
Each light comes with LED Mounting Brackets that can be used to affix almost any LED module or strip. The brackets use an ingenious slotting system that lets you easily adjust the position of the light and double-sided tape to affix the light to the brackets. In some cases drilling holes in the bracket to mount your particular light may be necessary, but we find the double-sided tape to be a pretty good solution that doesn't require any modification.
Mounting the Gisemann Steller can be done in a few ways, but the easiest is to use the Gisemann Stellar Tank Mount or Hanging Kit that are available. Tank mounting can make for a sleek look, but we have found hanging light fixtures gives the most benefit. Being able to change the height for maintenance, or even to tune the light intensity and spread, it is hard to beat a quality hanging kit. If you have tall ceilings the Giesemann Wall Mounting Brackets make a great solution to that problem.

Could have done better, but still ok By Peter on 4/15/2019Peter would recommend this product to a friendI had been waiting on a "better" hybrid retrofit after seeing pretty bad reviews of the Aquatic Life fixture. I bit on this one knowing Giesemann has a pretty solid reputation and owning the Aurora fixture (although not having used it yet). I have a couple heads up for anyone considering: 1- For some reason the US version doesn't come with splash guard over the T5 bulbs. Even thought the instruction sheet clearly shows them, and unboxing vids in Europe show them, BRS says the US version doens't have them. At about a $200 premium over the competition I had expected to have a couple pieces of acrylic thrown in. BRS suggested I have some fabricated. uhm. 2- No active cooling, so no fans to cool the bulbs which will reduce PAR somewhat when hot 3- I'm using AI Hydra 26's LED's and the brackets for holding them (and pretty much any other fixture) rely on 3M sticky tape to keep them from plunging into the tank. It does hold pretty well, but if I keep this fixture I'll be drilling some holes to use the AI mounting screws. 4- This sucker is wide, over 23" front to back so my 18" deep tank is missing some of the best light. The gap for LED in the middle is over 10" (only need half that for AI's). Maybe I'll learn not to bump my head when feeding.
Positives: Fixture definitely is nice and well built. Fit and finish are good, cords come out the same side, and T5 fixtures themselves seem very solid. Was pretty easy to put together.
