The ENERGY STAR is awarded to select fixture types that meet strict efficiency, quality, and lifetime criteria.
Because LEDs lights are relatively new, there are not many that are Energy Star approved yet.
However LED lighting is an intrinsically efficient lighting technology that is rapidly evolving and improving. LEDs produce light in a new way and many LED lights are already rated higher for quality and efficiency compared with existing lighting technologies, such as fluorescent and incandescent lights.
ENERGY STAR Qualified LED Lighting:
- Reduces energy costs — uses at least 75% less energy than incandescent lighting, saving on operating expenses.
- Reduces maintenance costs — an LED lamp lasts 35 to 50 times longer than incandescent lighting and between 2 to 5 times longer than fluorescent lighting.
- LED lamps reduce cooling costs because they produce very little heat.
- Comes with a minimum three-year warranty — far beyond the prevailing industry standard.
Overall Energy Star qualified products are becoming the standard on which a number of energy efficient “Green” standards are built. Energy Star qualified lighting is required for inclusion in Energy Star Homes and to meet National Green Building Standards.
These standards continue to mature and will continue to increase the demand for Energy Star qualified lighting, especially as energy costs continue to increase.
What Does Energy Star Qualified Mean On A LED (Solid State Lighting) Fixture?
The Energy Star logo is one of the most recognizable symbols of quality and performance. Energy Star qualification of LED lighting means the following key features and measurements
General Requirements
To qualify for ENERGY STAR, LED lighting products must pass a variety of tests to prove that the products will display the following characteristics:
- Brightness is equal to or greater than existing lighting technologies i.e. incandescent or fluorescent and the light is well distributed over the area lighted by the fixture.
- Light output remains constant over time, only decreasing towards the end of the rated lifetime (at least 25,000 hours for residential indoor and 35,000 hours for commercial lighting or 12 years based on use of 8 hours per day).
- Excellent color quality. The shade of white light appears clear and consistent over time.
- Efficiency is as good as or better than fluorescent lighting.
- Light comes on instantly when turned on.
- No flicker when dimmed.
- No off-state power draw. The fixture does not use power when it is turned off, with the exception of external controls, whose power should not exceed 0.5 watts in the off state.
- In addition to the tolerance, maximum temperature variances over its lifespan and viewing angle are defined.
- Color Rendering Index – (CRI) shall be a minimum of 75.

Save Power With Lunar Outdoor LightingA new outdoor lighting technology called “lunar-resonant streetlights” is coming that will enable streetlights to respond to ambient moonlight which dims and brightens each month in line with the moon’s phases? The beauty of this technology is that on clear nights when the moon is full, streetlights could turn off completely. This approach could save as much as 80–90 percent of the energy used for streetlighting. Equally, the technology could be used for domestic outdoor lighting applications to bring back the experience of natural moonlight and a star lit sky to residential areas. The concept is a small and simple intervention but it
Environment Friendly Outdoor LightingThe International Dark-Sky Association (IDA) is an excellent resource for finding manufacturers of environmentally friendly lighting. The IDA's mission is to preserve and protect the nighttime environment and our heritage of dark skies through quality outdoor lighting.
