DLC’s LUNA QPL Identifies Environmentally Responsible Lighting

Skyglow, light trespass, glare and color remain issues in outdoor lighting design. For the first time, the DesignLights Consortium (DLC) addressed them in technical requirements released December 2021, resulting in recent publication of a new Qualified Products List (QPL) as a subset of its QPL for solid-state lighting. LUNA version 1.0 identifies outdoor LED luminaires that save energy and promote responsible outdoor lighting.

“Ban the Bulb” is Back

My contribution to the June issue of ELECTRICAL CONTRACTOR describes two major Department of Energy rulings related to incandescent lamps–one that revises definitions to eliminate previous exemptions, and anohter that interprets the 2007 energy law’s backstop provision, which will eliminate a majority of lamps that previously complied.

Field-Adjustable Lighting

Field-adjustable (aka field-selectable) lighting is staple LED light fixtures and lamps that allow field selection of preset operating parameters such as light output and correlated color temperature (CCT). For the electrical distributor, they offer a means to consolidate inventory and more flexibly satisfy local demand for lighting products.

National Building Stock Study Reveals Ongoing Lighting Upgrade Opportunity

Commercial buildings in the United States are trending larger and more commonly feature LED lighting and occupancy sensors. While traditional light sources have declined in use, they remain prevalent in the nation’s estimated 5.9 million buildings, spelling a significant continuing upgrade opportunity, particularly in older buildings that have not been upgraded.
