Where I live, there is a DISPOSAL cost! One dollar per tube!

At USA average electricity cost of 10 cents per KWH, and assuming 45
watts of power consumption (including ballast losses) for a 4-footer, and
assuming you get only 6,000 hours life (they are rated much more, although
at 3 hours of runtime per start), over that 6,000 hours you save $33 in
electricity over a 100 watt incandescent. A 4-footer in a decent fixture
produces more light than a 100 watt incandescent. With 32 watt T8 bulbs
and electronic ballasts, power consumption per 4-foot bulb is more like 35
watts, maybe a little less.
$2-$3 to buy a fluorescent bulb and another dollar to get rid of it is
not so bad after all...
