The Wattage of the Led 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.
When you buy any lighting fixture, check the maximum wattage it will take. A bulb with too high a wattage can produce excess heat that can create a fire hazard or damage the fixture. Remember, wattage is the indication of how much power a bulb consumes, not the amount of light it generates. New U.S. packaging rules will make it easier to choose the light bulb that’s most efficient.
Efficiency ratings for bulbs
The U.S. Federal Trade Commission is requiring manufacturers of incandescent, compact fluorescent, and LED light bulbs to use new labeling on consumer packaging by mid-2011 to help consumers choose the most efficient bulbs for their needs.
40 Watt incandescent lamp produces only 380-460 lumens and uses 40 Watts of energy per hour.
100 Watt incandescent lamp produces 1700 – 1800 lumens and uses 100 Watts of energy per hour.
Direct sunlight is around 100k lumens and uses no amount of energy per hour.
This was an inefficient way of lighting and there have been many advances, such as the introduction of fluorescent and compact fluorescent lighting as well as metal halide, low pressure sodium and high pressure sodium. Fluorescent and compact fluorescent produce better lighting with lower wattage; however, have some environmental factors to take into consideration. Metal halide, LPS and HPS produce better lighting than standard incandescent; however, they are typically much higher in wattage and use much more power than their CFL or LED counterparts.
Switching to CFL or LED can provide the same or better lighting while using a fraction of the original power. For example, I use 7 Watt LED bulbs in my kitchen can lights and it is very bright. This was switching out from 32 Watt CFL lamps. Outside there were three 150 Watt incandescent bulbs for around a 150 sq ft area and have since been replaced with 13 Watt CFL lamps. Now the areas are lit with much better lighting while only costing a small percentage of the original power requirement.
