I have two 26-watt versions in a 20" incandescent hood. No modification
needed, except to improve the reflectivity of the black plastic. I went with
aluminum foil. The color is pretty yellow, but the plants in the 10-gallon
tank put off a stream of bubbles at the rate of about two fine bubbles per
second, without CO2 injection. I don't know if this constitutes pearling,
but the plants are doing good.
