GREEN CREATIVE offers a complete lineup of LED products that adhere to current national quality compliance standards including ENERGY STAR®, Design Lights Consortium (DLC®), and various California specific specifications (Title 20, Title 24, JA8, etc).
ENERGY STAR®
ENERGY STAR® is a US Environmental Protection Agency (EPA) sponsored program to promote environmental protection through energy efficient products and practices. Products that have been qualified by ENERGY STAR® have passed strict technical requirements and can be considered energy efficient and reliable.
The DesignLights Consortium (DLC®)
The DesignLights Consortium® is a non-profit group funded by a variety of utilities and other industry groups with the goal of accelerating widespread adoption of energy efficient commercial lighting. DLC® develops technical requirements for various LED luminaires and other lighting technologies primarily in commercial applications not covered by ENERGY STAR®.
To be eligible products must meet the current DLC Technical requirements V5.1. There are specific requirements for Luminaires, Retrofit Kits, lamps, as well as networked controls. Although different than ENERGY STAR® requirements, the specifications focus on similar criteria such as efficacy, CCT, color rendering, and warranty. DLC® requirements are also unique for very specific product use categories.
DLC® Premium is a higher tier designation that requires more stringent technical requirements (outlined in DLC V5.1 link above).
