hot lamp / lamp

“Hot lamp” is simply using 2 energies at once.
We know that a lamp turned on is hot. Do you know how does the lamp operate?
When electronic energy changes to light energy, actually, the heat energy more appears than the light energy. Additionally, the percentage of the heat energy is 80%.
Light energy is just 20%. Therefore, I try to use both energies at the same time.
it looks like shelf. So, we can put it on something and something to be hit up. For example; on winter, when you study or something you turn on the lamp and sometime put a warm blanket, and you heat the blanket up on the hot lamp and you can make the blanket warmer.
