I've started a 65 gallon cube with one from Stray Light Optical. The lamp is manufactured by Luxim. Since the tank is new there's only rock, but the color looks great 50% or less. Which even at minimum it's plenty of light.
Here's a review by some professionals
Dear Robby,
Thank you for visiting the Aquarium and for writing us with your question regarding plasma lighting in our exhibits. I asked an aquarist here for the information you're looking for, and here's what he said:
"œWe are using plasma lighting over many exhibits now here at the Aquarium. The tanks range in all sizes and depths, and they are all custom built so I cannot give you a LxWxH without knowing exactly which tank you are talking about. What will probably be most helpful are some PAR numbers that we got from a side by side comparison with a 400W metal halide (Blueline E ballast and 6500K bulb). At 1.5" depth, the plasma puts out 660 µmol/(m*sec^2), the Blueline only put out 271 µmol/(m*sec^2) at the same exact depth. At 24" deep, the plasma put out 179 µmol/(m*sec^2) and the Blueline only 81 µmol/(m*sec^2). With the plasma dimmed to 25% it still beat the Blueline MH with 127 µmol/(m*sec^2) at 24" depth. Overall the plasma lights perform more like a 600W metal halide, suitable for almost any home aquarium. I would not recommend using the current plasma models over tanks with coral that are deeper than 36". They only use ~280 watts, are dimmable (we have had problems with units that constantly dim, though they are working on the firmware to better support dimming) and they have a useable life of ~8-10 years depending on how much output you want. The spectrum produced by the bulb is the closest to sunlight than any other known light source on the market, a true 96 CRI. You can buy fixtures from Straylight Optical and Sfiligoi."
Thanks again for writing, and I hope this answers your question. We are constantly striving to make the Aquarium the best it can be, and our visitors' thoughts and suggestions help us in reaching this goal.
