In a recent issue of LEDs Magazine, Dr. Nadarajah Narendran, Director of Research at the Lighting Research Center, discussed LRC research focused on LED system reliability that revealed that some LED products available on the commercial market can fail much sooner in some applications than manufacturers’ lamp life specifications would suggest. The studies found that [...]

My contribution to the July issue of ELECTRICAL CONTRACTOR talks about dimming curves and why they’re important. As dimming becomes more important, electrical contractors may benefit by becoming familiar with dimming curves. The dimming curve defines how dimmers set voltage output in response to control signal input, such as a slider position. Intuitively, it would [...]

O’Boyle (Philips Lighting) discussed power over Ethernet (PoE) systems at the National Lighting Bureau’s Annual Lighting Forum during a session called “Illuminating the Future, Part One”. Randy Reid (EdisonReport) moderated. According to Isaacson and O’Boyle, PoE differs from conventional DC networks in that the cabling used can carry [...]

Norma Frank, CLMC recently contributed a maintenance column to LD+A that talks about LED streetlighting maintenance. Traditionally, HID luminaires are cleaned when they are relamped, limiting light loss imposed by luminaire dirt depreciation (LDD). As stated above, LED luminaires promise much longer service life. They may present a different failure mode based on output rather [...]
