I'm doing my own lighting research. First I don't own any of these lights so what I'm saying is from research and reading user reviews. From this I believe the Marineland single bright are totally inadequate for plants. The double bright should be okay for low light plants. Of course the most expensive Marinland plant light would probably be the best of their selections, but it is quite pricey. On the Current satellite lights, double check your lengths in your price comparisons. The plus has more wattage and a programmable remote. You can find pictures and specs at Aquarium Lighting, LED Aquarium Lights, Complete Aquariums - Current USA
. I'm guessing the higher wattage would be better for plants, but the specs don't truly address that. They appear to be full spectrum and the plus version would allow you to adjust the color to your taste. The fluval performance has more led
wattage than the satellite plus, but again comes at a higher price and without the fun factor of the satellite. A lot depends on your budget and your needs. On the fluval be sure you get the freshwater plant version as opposed to the marine version. None of the lights seem to give the kind of technical information needed to give a true comparison. So it's still down to reading the specs, choosing your price point, analyzing your needs and hoping when all is said and done you haven't thrown a lot of money at a light that won't grow your plants. Because I only have easy and undemanding plants, and want to stay low tech on the aquaculture, I'm leaning towards the satellite plus. Then again next month someone else will come out with something even more appealing, or so it has been going on freshwater LEDs.
