The Wattage of the light is the amount of energy it takes to produce a certain amount of light. The higher the wattage, the brighter the light, but also the more power it uses. The efficiency of this system was introduced using incandescent lamps. For instance: 1. 40 Watt incandescent lamp produces only 380-460 lumens. .
A lumen is the amount of light a certain lamp gives off. If replacing a standard 150 Watt light bulb which gives off around 2600 Lumens, using a 42 Watt CFL or a 25 Watt LED is about the equivalent. This lowers the needed power. .
Solar lighting needs to take into consideration both the Lumens and the Wattage of a lamp. The wattage provides the needed power from the solar power and battery systemto.
