Evaluating LED Luminaire Reliability

A brief article I wrote for tED Magazine. Reprinted with permission. While LED promises long service life as one of its primary advantages, accurately projecting lifetime remains a challenge. The Next Generation Industry Alliance’s (NGIL) LED System Reliability Consortium (LSRC) recently updated a key report, LED Luminaire Lifetime: Recommendations for Testing and Reporting, to shed [...]

ELECTRICAL CONTRACTOR on LED Lighting

Recently read an interesting article about LED lighting in ELECTRICAL CONTRACTOR. Early on, a quote from Kevin Willmorth: “LEDs bring a global rethink,” said Kevin Willmorth, owner of Lumenique LLC, a lighting product development and consultant firm in Germantown, Wis. “They introduce us to a new era of lighting as an appliance. But this new [...]

Another Novel Lighting Technology: Nanowires

BizLED recently published an interesting story about a solid-state lighting technology that could become efficient enough to take on the LED: nanowires. I’ve theorized that given LED’s efficiency and performance, it may well be the last major light source for the foreseeable future. There will continue to be a great deal of innovation for many [...]

HID Lamp Indexes Decline During First Quarter 2015

NEMA’s shipment indexes for high intensity discharge (HID) lamps continued to decline at the start of 2015. Sodium vapor lamp shipments fell 11.5% on a seasonally adjusted basis compared to the same period last year. Shipments of mercury vapor lamps retreated by 18.4% year-over-year (y/y). Although the index for metal halide lamps registered a modest [...]

NEMA Issues Position Paper on LED Flicker

Yesterday, LightNOW published a guest blog post by Jim Brodrick, DOE’s SSL Program Manager, on a new IEEE recommended practice on LED flicker. As metrics, IEEE uses % flicker, operating frequency and flicker index. A graphic is provided that plots % flicker relative to the light source’s operating frequency. Color shading reveals safe and low-risk [...]

Brodrick on New Recommended Practice for LED Flicker

Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, SSL Program Manager, U.S. Department of Energy The emergence of high-frequency electronic ballasts for use with fluorescent lighting did away with most general-illumination flicker concerns back in the 1990s. That is, until the advent of LEDs, which have put [...]
