Congress passed the National Energy Policy Act of 1992 (EPACT) which
besides calling for more energy labeling, it also calls for the phasing out
of all commercial use of 40w cool white bulbs. They're replacing the
40W CW T12 bulbs with 34 Watt T8 bulbs and energy saving electronic ballast.
As mentioned on this list several times, these bulbs and ballast produce
about the same amount of light with about half the total energy being
used.(bulbs + ballast) Eventually, this means to every day folks is
that 40W T12 bulbs are going to get harder and harder to find as the bulb
manufacture begin the phasing out production of this type of bulb.
I'm not sure what the Aquarium bulb/hood manufactures are going to do.
