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.
