I brought 220v bulbs back from Europe in 74, they have lasted 10-15
years run apx 6 hrs a day, google 220v bulbs. With incandesant bulbs
they are truely "Heaters" out puting only apx 10% light and 90% heat.
But you still loose that 10%. why wouldnt one 40 watt pipe freeze wire
just hanging work, you will get very long safe life and 100% heat
output.

Actually you would not loose even that 10% in a typical pump house. The
light will fall on a wall, where it is absorbed and turned to heat. Both
kinds of bulbs are 100% efficient unless the light leaves the room as light.
