The power consumption of different light sources varies based on technology:
Filament Bulb: Highest power consumption as it relies on heating a filament.
Tubelight: Moderate power consumption but higher than CFL and LED.
CFL (Compact Fluorescent Lamp): Lower power consumption compared to Tubelight and Filament Bulb.
LED (Light Emitting Diode): Lowest power consumption with high efficiency.
Order of power consumption (highest to lowest):
