Is there someone out there who can provide a firm answer to >the question? During the winter, I don't bother to turn my lights out unless the actual light is bothering me ... my house is electrically heated ... the electric power "wasted" by the lights simply helps to heat my house ... same price as what goes into the furnace. Also helps reduce wear & tear on switches, ballasts, etc. During the hot summer months, you pay significantly more than twice as much for that waste heat, at least if you have air conditioning. Then, the "wasted" electric power heats my home and requires additional electricity to remove the heat. I think the answer is pretty dependent on the type of building, geographic location and time of year, etc. -- |---------------------------------------------------------------| | // Wayne D.
