Photoelectric parameters
Incandescent bulb lamp can only operate at rated voltage to obtain various specified characteristics. The power and luminous flux of incandescent lamps increase with higher voltage and decrease with lower voltage.
Luminous Efficiency means lumen per watt. Incandescent bulb luminous efficiency is about 6-15 lm/W. For the same type of filament, the higher the power, the higher the luminous efficiency. The efficiency of double filament is higher than single filament at the same watt.
The Color temperature of Incamdescent bulb is 2300-2900K, CRI is 99-100. These two parameters cannot be altered artificially.
Incanescent bulb PF=1
All of incandescent bulbs are dimmable
Incandescent lamps are thermal radiation light sources, featuring a continuous spectral energy (power) distribution
