I am looking to whip up a cheap heater to cover a smaller enclosed area
where some pipes are. What i thought of doing was using two 100 watt
lights and maybe a surplus muffin fan or such. Now, my thought was to
connect the two 100 watt bulbs in series. My theory on this (fact or
not) is that normally the incandescent bulbs are good for 1000/1500
hours or so. putting them in series should increase the life hours
due to derating and burning the tungsten less bright. I don't care about
the light output, just that they generate some heat. ANy thoughts?

This will work nicely, especially if you have a maze of pipes
rendering heat-tape impractical, or you cannot afford the initial cost
of the heat tape. But, be SURE to put some sort of external indicator
such that you will have a visible cue if there is a lamp or fuse
failure. You might find that critters are drawn to the heat and might
chew something they shouldn't.
You may not need a fan if the area is tight enough - and it adds
another failure point in any case. It also serves well to insulate the
pipes in addition to providing the heat, again if you can.
