The DesignLightsConsortium, a collaboration of utility companies and energy efficiency
organizations, is a leading resource
for energy efficient commercial lighting performance
information. The DLC publishes a listing of LED luminaires that meet strict energy efficiency and
performance criteria This listing is called the DLC QPL. LED lighting manufacturers
listed on the DLC QPL meet the preliminary requirement for utility incentive
eligibility from DLC member firms.
The
DesignLights Consortium recently announced their final technical requirements
for LED lighting manufacturers to qualify their LED lighting products on the
DLC Qualified Product List. The updated requirements insure that the QPL listing will continue to
be a valuable resource for companies searching for high performance LED
lighting.
LED Tube Lights Qualify for Energy Efficient Lighting Rebates
One change under the new requirements is a revised policy for
Four-foot LED Linear Replacement Lamps, LED Tube lights that replace T8
fluorescent lamps. These products will all be categorized under the Four-foot
Linear Replacement Lamp classification.The technical requirements are intended to evaluate the
performance of the lamp itself and in a reference 2x4 troffer. One of the most
important technical requirements for bulb performance is for System Light
Efficacy. The DLC requirement for bulb performance is ≥ 100 LPW and in situ
performance-≥ 85 LPW.
RedBird LED, an Atlanta based LED Tube light
manufacturer, has the highest commercially available lighting efficacy for this
category on the DLC QPL list. Their Cardinal LED Linear products have Installed
efficacies (the ratio of light-output to power consumed) up to 110 lumens/watt,
making them some of the most energy efficient LED lighting products available
today.
