5 watt vs 3 Watt

Hey guys, comparing equal watts does a 5 watt generator lot more heat than a 3 Watt? I know that a 5 watt has more penetration. my question if I take a 3 Watt and a 5 watt light with the same wattage will the five watt produce a lot more heat? And if so approximately how much more of a percentage would it be?

5 watts is approximately 17 BTUs per hour, and 3 watts is approximately 10 BTUs per hour.

A 3 watt light has about 60% of the energy that a 5 watt light has.
