Unless I'm mistaken, this style of bulb is rated like a normal
incandescent bulb, i.e., an 85-watt PC bulb puts out as much light as an
85-watt incandescent bulb.  The light output of incandescent bulbs is
about 1/4 of the light output of fluorescent bulbs per watt.

You might want to check the lumen rating to see how they compare. For
reference, a 55-watt PC bulb from AH Supply produces 4600 lumens.

This will greatly affect your "watts/gallon" calculation and may inidcate
that these bulbs are not very cost-effective.

Unless I'm mistaken, of course.
