Answer 2

Answer:

Incandescent and CFL bulbs get so hot because most of their energy is being released as heat, not light, making them much more ineffeicient. Proprietary tests show 100W incandescent lights burning at 335.4 F, CFL lights burning at 179.2 F and LED bulbs burning at 87.2 F.

cold sources of light are those that do not require heat in order to product light. example, LEDs, fluorescent lights, fireflies, some algae.
