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?
