does the vessel where the light bulb is placed affect the heat
0. A light bulb no matter what kind is a hardware problem.
mostly light and heat (infrared)
This is a matter of opinion, but the light bulb gets my vote for increased safety and productivity.
It doesn't matter where the bulb is in respect to the battery, as long as the circuit is complete, the bulb will light up.
The heat given off by a light bulb is thermal energy. The light itself is electromagnetic energy. All chemical energy is potential or stored energy.
This light bulb does not produce heat and that is why it is given that name
it is a closed system. no matter or energy flows across the boundary
