What is BR30 for a light bulb?

A traditional incandescent BR30 is a simple device that heats up a filament to such a high temperature (2700 degrees Kelvin) that it emits light. Dimming such a bulb is fairly straightforward – simply limiting the amount of electricity flowing to the lamp allows the lamp’s filament to cool down, resulting in a lower amount of light output.
