Is there any difference in the light emitted from an LED and light emitted from a light bulb?
In: Physics
It really depends on the lightbulb and led. Technically yes there is a difference.
The visible light for humans is between the wavelength of 380nm to 780nm (380nm ultraviolet, 780nm infrared). Everything between ranging from blue to red.
A normal household lightbulb doesn’t emit all the wavelengths equally, but with a focus towards one colour (see how the light indoors is mostly warm / orange)
An LED doesnt cover the exact same spectrum the normal lightbulb does. Maybe this graph can illustrate it better
