Hi,

The first is a link for a bulb, not a fixture.

Yes. I may have not been so clear..hahahaha I meant is this wattage bulb too much for a 20 gallon long cause i want to grow low/medium light plants.

jpappy789 · Jul 3, 2009

The site doesn't specify the wattage of the bulbs...only the K rating.

K's (Kelvins) are the "color" of the bulb and have nothing to do with the wattage.

Paintballer, you seem a bit confused about aquarium lighting. Here's a great article you should read over. http://www.americanaquariumproducts.com/Aquarium_Lighting.html

Yes, kelvin (K) is an expression of temperature, wattage (W) is power or energy conversion.

oh ok, thanks for clearing that up.
