I have just bought a new 55g tank kit that came with LED lights. I have had many planted tanks in the past and they all had florescent tubes so i just swapped them out with "grow lights". I have not dealt with LEDs as it has been a new thing since I had my last tank. I have the Marineland led lights that came with the tank set. I have two of them and the specs for each on are as follows.
- # and color of lights - 42white/3blue
- total watts per fixture - 4.62
- total LUX - 990
- total Lumens at 12" - 310
- Kelvin rating - 5500
