you're missing the fact that that is the key point. the heat that is generated is not pointed at the person in front of the light. in photo/video, this is huge. talent/models don't sweat from standing in front of the lights. food products don't melt/wilt under the heat either. nobody really cares about the heat pointed away from the subjects.

For photography I agree. But if you're trying to create a "sun at home" because you don't have enough light/no chance to get sunlight, to feel the warm of the light can be nice...
