Renaissance Lighting’s architectural-grade 4- and7-in. RGB LED downlights utilize the company’s Rhapsody Color Management System, which enables the creation of intelligent color effects from these luminaires. Nora Lighting’s new LED recessed downlights, designed for light commercial and residential applications, include three 120V models: a 4-in. 11W luminaire and 5- and 6-in. 15W luminaires. All three [...]

The seventh annual DOE Solid-State Lighting R&D Workshop, held February 2-4 in Raleigh, NC, drew 350 attendees sharing updates, including stakeholders from industry, academia, research institutions and government. Both speakers and attendees offered insights on key issues inhibiting SSL technology and how to move past current limits of SSL efficacy and performance, which will inform [...]

The Star-Ledger recently reported the story of Herman Goldman, a 96-year-old who has worked for Capitol Lighting, one of New Jersey’s oldest family-owned lighting stores, for nearly 70 years. Four out of five days a week, he can be found rebuilding luminaires as Capitol Lighting’s clearance manager. Check out the story here.

This week, I helped lighting industry and LIGHTFAIR Innovation Awards veteran Mark Roush edit the manufacturer entries. I can’t say how many there were, but trust me when I say it was a lot. By the end of the process, my head was spinning. Manufacturers should take note, however, that while we’re happy to do [...]

To reduce peak demand with lighting, we can turn it off, turn it down or use it more efficiently. Since lighting is critical for productivity and safety in many indoor spaces, turning it down instead of off is usually more desirable. Dimmable lighting therefore has a strong potential role to play in demand response. But [...]

Today’s focus on saving energy is accelerating demand for luminaires designed to achieve a high level of energy efficiency. Luminaires can be evaluated based on luminaire center beam candlepower (candela), total input watts (W), efficiency (fraction of lamp lumens that exit the luminaire), efficacy rating (lumens/W), coefficient of utilization (CU) and comparative yearly energy cost [...]
