The hidden killer consideration is in the last sentence. You can only
sensibly use these units in rooms where it's switched on first thing in the
morning and off last thing at nite (or left on 24/7/365.25). I had one in
the kitchen, where I do a lot of mooching and reading, and it lasted a long
time. I put another in the bathroom, where I ditto but in shorter and much
more frequent intervals, and the bastard died after a year or less. Okay,
it used less juice, but it cost about 10 to 20 times as much to purchase a
fluoro. Ferggeddit.

The LED idea might be a goer, though.
