According to Steve Cunningham from GE Lighting, receiving the Energy Star label requires a lot of work and dedication to meet a strict set of standards.
Cunningham says the label was established to reduce greenhouse gas emissions and other pollutants caused by the inefficient use of energy. It's also designed to help consumers identify quality light bulbs and other items.
One of the stipulations for LED bulbs is that it must have omni-directional light. The testing process also involves finding out how durable a light bulb actually is.
Cunningham says CFL spiral bulbs go through rigorous testing, where experts will turn the light off and on several thousand times to make sure it will last as long as it's supposed to.
So now that you're more aware of the process, be sure to look for the Energy Star label on eco-friendly products. It's basically a guarantee that you're purchasing a quality item that will also save you money in the long run.
