Eighteen specific 3000K models, of the XSPW Version B Wall Mount Luminaire manufactured by Cree Lighting, are the first outdoor LED products published on the DLC’s LUNA QPL.
LUNA-qualified products are eligible for energy efficiency rebates and incentives designed for SSL V5.1 products. LUNA sets performance requirements for specific categories of outdoor LED fixtures, so that municipalities, energy efficiency programs, and other outdoor lighting decision-makers can better support their energy reduction goals and abide by dark sky policies and ordinances. LUNA also helps specifiers fulfill the light pollution and trespass requirements of LEED and WELL building programs, and helps projects follow application guidance in the joint International Dark Sky Association-Illuminating Engineering Society Model Lighting Ordinance.
In addition to meeting the DLC’s SSL V5.1 efficacy thresholds, LUNA-qualified products must comply with additional dimming, control, and shielding requirements to ensure efficient use of lighting energy. The LUNA program also introduces requirements for light distribution, correlated color temperature, and dimming controls to reduce light trespass and sky glow, while supporting light installations that both provide appropriate visibility for people and meet recommended methods and voluntary guidelines for dark-sky best practices. The LUNA QPL products work to mitigate the growing problems associated with light pollution.
The DLC notes that the technical requirements apply only to white-light LED outdoor products, which do not include some types of outdoor lighting. For example, non-white (amber) luminaires, which may be appropriate for settings such as environmentally sensitive areas, are excluded from LUNA. This is because of inconsistencies in terminology and performance due to the lack of standardized metrics, which are still in development for non-white light.
