How many photons does a light bulb emit

Web6 apr. 2024 · Incoherent light is emitted by many common sources, such as an old-fashioned incandescent lightbulb or an LED bulb. This light is called incoherent since the photons are emitted with different wavelengths and in a random fashion. A beam of light from a laser, however, does not spread and diffuse because the photons have the … Web7 dec. 2024 · $\begingroup$ A 50 W light bulb does not emit 50 J/s of light. Most of the 50 W is wasted as heat. Heat is not light. Most heat is not even considered IR. An IR or UV bulb might emit some light, but IR and UV are not considered "light". In normal language, light means visible light. Your question is quite silly, unless you has some purpose for it.
