Good morning Jeff...
The bulb is the right color. The 6500 K
is recommended for growing aquatic plants because it best mimics natural daylight, 5500 K
The wattage is considerable, but I don't see how it will work in a standard aquarium strip. The bulb appears very short, so you'd likely need more than one to light the length of your tank.
Using this type of lighting seems to me to be more work and less payback. Using more conventional lighting would be less effort and probably require less money.
Just one reporter's opinion.
