Actually 40W tubes are legal at the moment, but only in the premium
phosphors, not the old halophosphate stuff (CW, WW, etc) though far less
efficient incandescent stuff has regulations at all thanks to the usual
beaurocratic nonsense that makes up our largely useless energy laws. The
thing is, few "40W" ballasts run the lamps at anywhere near full power, so a
pair of 32W T8's on an electronic ballast are actually considerably brighter
than a pair of 40W T12's, plus you get no flicker. You can even get ballasts
that overdrive the lamps if you need more light, but it's easier to just use
more lamps and cheap T8 ballasts you can get at a hardware store to run up
to 4 lamps each. Personally I like F32T8/850's, 86 CRI 5000K, nice bright
clean white light.
