Power Consumption

Power consumption is often referred to as lamp power or wattage (the latter term comes from English). It describes the electrical power drawn from the power supply by a ballast or a lamp, measured in watts (abbreviated as W). Simply put, power consumption indicates how much electricity a light fixture must draw in order to illuminate. If you want to know the total system power or system power consumption, this is very easy to determine or calculate for both low-pressure and high-pressure discharge lamps using the power consumption. You simply need to add the power and the power consumption of the ballast, and you’ll know the system power (consumption).
