Incandescent light bulb characteristics
Incandescent lamps are nearly pure resistive loads with a power factor of 1. Unlike discharge lamps or LED lamps, the power consumed is equal to the apparent power in the circuit. Incandescent light bulbs are usually marketed according to the electrical power consumed. This depends mainly on the operating resistance of the filament. For two bulbs of the same voltage, and type, the higher-powered bulb gives more light. WebThe first incandescent lamps had 2 disadvantages, short lifetime and low efficiency. The evaporation and oxidation of the incandescent carbon can be avoided by a structure made of carbon nanotubes that works in argon. The claimed lifetime (based on accelerated aging tests) is as good as for LEDs.
