I had a debate with a friend. It was 90 degrees outside and we were in a building with no air conditioning. She wanted to keep the lights off to keep it cooler. I said that the fluorescent light bulbs produced negligible heat and that turning them on would not make the room hotter.

Fluorescent lamps are more efficient than incandescent lamps, meaning that a larger percentage of energy is released as light instead of as heat. However, they are still far from 100% efficient (the theoretical limit, and a practical impossibility). Incandescent lamps have an efficiency of at most about 5%, while fluorescent lamps may be up to 15% efficient. So fluorescent lights do release some heat, but less than incandescent light bulbs

The performance of a bulb is around 20%. So 80% comes off as warmth. Your 60W bulb is almost a 48W heater. From one advert on small heater: "The Presto Parabolic warmth Dish is a less costly decision for workshops or garages once you prefer to warmth in basic terms you and not the completed development. the comfortable Legs radiant warmth panel, with purely a hundred watts of warmth output is by using no potential an entire room heater, yet performs admirably while put in under a table or held on the wall to heat a fowl cage." From here we can see that the 60W bulb is a pair of million/2 the potential of this "own" heater. So definite in case you're close to the bulb, and not as lots in case you have a large room. you may desire to alter the bulb to a fluorescent gentle that's 5X greater valuable and you does not have this situation of warmth. additionally, your capability decrease fee expenditures ($$$) would be significant over the years and you additionally are helping the ambience.

Negligible is still heat. So she has a little bit of an argument.
But turning them off will not make it much cooler and could have made it hotter if you took the initiative and said, "Baby why don't we just go ly down in be with the fan on us and cool down. ... ... ..

Fluorescent lights make me crazy...they flicker like mad and then I get upset and start running around the room bumping into things and I do this until I collapse from exhaustion...so yes, they do make me feel hotter...

Try touching a fluorescent light bulb (CAREFULLY!!!), and you'll feel the heat.

on your subject "Do fluorescent light bulbs make you feel hotter?"
it doesn't make you feel hot, that's one purpose why Agapito Flores invented it. but fluorescent light bulbs emit heat but its very very minimal
