Incandescent light bulbs are very useful.
They are a high dissipation resistor with a lot of uses.
I have one in series with a bathroom ceiling fan, just kept plugging
smaller watt values in
until the fan was quiet enough but still fully functional.
I have one in series with a micro drill press, runs with full revs
but stops when the drill jams.
It will be a pity to see them turn to unobtainium.
cheers,

I now have my house converted over completely to LED bulbs... over
300 of them (mostly PAR16/PAR20/PAR30/PAR38 bulbs)! At retail the
cost would have been over $15,000 dollars!!! Totally insane... I
have a large closet totally dedicated to light bulbs. When
incandecents/halogens are no longer made I'll sell all the ones
that I have removed and become stinkin' rich.
Then I found an Ebay seller that was selling "used" bulbs for dirt
cheap (like <$5 for a PAR20 and $10 for a PAR30... actually less
than the halogens cost). They are apparently store/utility company
returns (Bubba buys a replacement bulb and can't figure out how to
install it so returns it to the store). I was replacing a couple
incandecent bulbs every week (many times they killed a $35 dimmer
when they blew). Only one of the LED bulbs has failed in the last
year.
I did have to build 32 custom fixtures to replace the 900 lumen/50
watt/12V halogen MR-16 bulbs. The brightest MR-16 LED bulb
available is around 300 lumens.
If you use PAR20 bulbs in your house check out: http://

These are some of the best PAR20 bulbs out there and the lots of 10
usually go for less than $60. The exact same bulbs sell for $40
each a Lowes.
