You can’t heat a chicken coop with a fluorescent bulb.

Or the pumphouse, either.

First line of defense is a 60W bulb, which is often enough to keep the heat tapes on the pipes from kicking in.

That’s right or under the kitchen sink on those sub-zero nights. REAL Americans know the value of an incandescent bulb! ;^)
