In this article published in LEDs Magazine, Mark Rea, Director of the Lighting Research Center, and Jean Paul Freyssinier, Senior Research Scientist for the LRC, propose a new definition for the lumen. This lumen should be used in product regulations instead of CRI, as CRI arguably does not align to consumer preferences for color rendering. [...]

Lumileds has introduced an online calculator that luminaire manufacturers can use to more quickly optimize the design of their grow lights. The calculator allows the user to input various LED combinations and operating conditions to generate the spectral power distribution, photosynthetic photon flux (PPF), and power usage of a fixture using Lumileds LUXEON SunPlus Series [...]

The Northwest Lighting Network recently published a short list of best practices for lighting retrofits provided by senior lighting specialist Jeff Anderson. He says to be comprehensive about the retrofit. Instead of focusing on the most visible opportunities, look at everything from exit signs to portable lighting. Consider all options for upgrade, noting that different [...]

New LED lights that are being installed in milk display cases across the country do more than just reduce energy bills — they also help milk taste better, Virginia Tech researchers have found. The exposure to certain light changes the flavor profile of milk. Milk fresh from the dairy should taste sweet and rich but [...]
