Quantum parameters of light bulbs
WebSep 1, 2012 · Fluorescent lights convert more than 20% of the electrical energy to light, which is 10 times more efficient than incandescent light bulbs. Furthermore, they generate only about one-third of the heat that an incandescent light bulb generates, significantly reducing the heat production for the same amount of light production. Webquantum, in physics, discrete natural unit, or packet, of energy, charge, angular momentum, or other physical property. Light, for example, appearing in some respects as a continuous …
