Like The Light BULB :P
A fluorescent bulb
A light bulb that uses a filament is also known as an incandescent light bulb.
When the bulb is lit it uses energy. When there is no bulb, no energy is used even if it is switched on.
The quantity of power consumed by a light bulb is dependant on the wattage of the bulb.
A light bulb uses energy. It uses electricity.
That depends on the type of bulb AND on it's power usage. An old incandescent bulb of 100 watts uses about an amp, a 60 watt uses about a half amp. But a florescent bulb putting out the same light would consume about half the current, and a LED bulb would use less than half that.
My ML320 (2002) uses an standard H7 bulb.
To provide illumination
Light+Heat
When you compare a CFL (Compact Fluorescent Lamp) bulb to an LED bulb, the CFL bulb has a shorter lifespan. The CFL bulb also uses more electricity for the same brightness Also a CFL lasts longer and uses less electricity (for the same brightness) than an incandescent bulb.
The Aygo uses a H4 type of bulb
The bulb uses 5 watts of power.
