Since we have had near 0 f weather here I can see why a regular or hid bulb would be used over a cf one. This cold weather makes the cf bulbs dim,very dim. No idea if they use more power when they are dimmer vs full brightness,but the mercury vapor one we have had no change in brightness.
I recently purchased a keroscene round heater to use to supplement our heat pump. As you may of may not know they start to slack off as the temps go below freezing of water. Its all electric at that point. Ive used the keroscene heater on its lowest setting af ew hour every evening and its very fuel efficient. Think a gallon is like 3,50 a gallon. Nice to have incase the power fails.
