I am a little confused here. I am going to get a 55watt Power Compact light for my 20gal Tank(perhaps 40 gal soon) I went to AquaticBotanic and read the article on lighting. The section on Kelvin caught my eye because of this... "Color Spectrum or kelvin
The term kelvin designates the color spectrum of the light bulb. A "full spectrum" bulb is anything between 5000k and 6500k. This has nothing to do with brightness, and bulbs that are very high in the color spectrum, (10,000k) have no value to plant growth. Standard fluorescent, VHOs, and MH all come in full spectrum."(Robert Paul H.)
Does this mean that a bulb with 10,000K won't give a plant the needed light, or does it mean that a buld with that much Kelvin is just over kill, but still covers the neccessary 5000k-6500k? I couldn't find a bulb that was high enough watts but down in the 5000k-6500k range.
