Reply to comment by bodhipooh in Do you think a $200 electric bill for a 2 bedroom is too much? by TechnologyPale329

Even if it were 0% efficiency 60W is 60W of heat. That’s negligible. A fresh cup of coffee on your desk is heating the room up more.

You are really missing the math on this one. It is 60 W spent to power the bulb, with about 95% of that radiated as heat. You combine that several times over for the amount of bulbs turned on at any given time, and then you have to remove that heat from the ambient temperature by using MORE energy to power the AC. In essence, it is x2 for whatever bulb wattage. In new construction luxury buildings, where recessed lighting are common, and multiples of those, you could be looking at 6 - 10 bulbs turned on at once.
