ENERGY STAR is a government agency set up to promote environmental protection through energy efficient products and practices. Products that have been qualified by ENERGY STAR have passed strict requirements and can be considered energy efficient and reliable.
The ENERGY STAR program requirement for integral LED lamps (retrofit sources) was drafted in 2009 and has been updated to the new Final Specification V1.1. ENERGY STAR Lamps Specification Version 2.0 is under development now but will go into effect on January 2, 2017. Information on the lamps specification revision process can be found on the Lamps Specification V2.0 page.
In order to qualify for ENERGY STAR, LED lamps must comply with the following requirements (summarized)
– Min. efficacy 55-65lm / W for omnidirectional lamps
– Min. efficacy 40-50lm / W for directional lamps
– Min. efficacy 45-60lm/ W for decorative lamps
– Omnidirectional lamps must have a reported min. light output (in lumens) ≥ 10 to 17 times the incandescent lamp’s rated wattage (depending on the incandescent lamp’s rated wattage)
– Decorative lamps must have a reported min. light output (in lumens) ≥ 6 to 17 times the incandescent lamp’s rated wattage (depending on the incandescent lamp’s rated wattage)
– Equivalence for non-directional lamps is based on the ENERGY STAR lumen output equivalence table
– BR directional lamps must have a reported min. light output (in lumens) ≥ 10.5 to 15 times the incandescent lamp’s rated wattage
– MR and PAR directional lamp center beam intensity shall be ≥ the center beam intensity value calculated by the ENERGY STAR Lamp Center Beam Intensity Benchmark Tool for the referenced incandescent lamp
– Color temperature with strict tolerance
– Color maintenance (stability) measured over 6000 hrs
– CRI of Min. 80 (77 on average)
– Power factor ≥ 0.7 if power > 5W
– UL + FCC certification
– Lamp life claims ≤ 25,000 hrs, but ≥ 15,000 hrs, lamp shall maintain 86.7% to 91.8% of 0-hour light output after a min of 6,000 hrs testing
– Lamp life claims > 25,000 hrs, lamp shall maintain ≥ 91.5% of 0-hour light output after a min of 7,500 hrs testing
– Directional lamps must have at least 80% light output within an angle of 120°
– Omnidirectional lamps must have an even luminous intensity distribution within 0° to 180° and at least 5% of total flux in the 135° to 180° zone
– Decorative lamps must have an even luminous intensity distribution within 0° to 180° and at least 5% of total flux in the 110° to 180° zone
– Rapid cycle stress: lamp, cycled at 2 minutes on, 2 minutes off, or 5 minutes on, 5 minutes off, shall survive the lesser number of cycles; one cycle per hour of rated life or 15,000 cycles
– Manufacturer must participate in the Department of Energy’s Quality Advocates program and use the Lighting Facts label
– All testing reports submitted for application must be issued by a DOE CALIPER recognized or NVLAP LM-79-08 accredited laboratory
– 2 year min. warranty for lamps with life rating < 15,000 hrs
– 3 year min. warranty for lamps with life rating ≥ 15,000 hrs
Many LED suppliers around the world make false claims about their products. Additionally, because of engineering and quality problems, many more LED light sources have disappointed buyers who were originally excited about this new technology. Generally, when purchasing an ENERGY STAR qualified LED lamp, the risk of product failure is significantly lowered.
GREEN CREATIVE is proud to be an ENERGY STAR partner.
