Upgrading Fluorescent Luminaires to LED: What Happens to the UL Listing?
When a fluorescent luminaire is upgraded to LED, what happens to its electrical safety certification? It depends on whether the new lighting is an LED luminaire, LED retrofit kit or LED replacement lamp. DOE has some guidance here. UL has some guidance here. Paraphrasing the documents, in a nutshell: All new components should carry proper [...]

Sizing Up Induction Lighting
Below is an article about induction lighting I contributed to the July issue of TED Magazine. Reprinted with permission. Induction lighting offers a longer-lasting alternative to HID and a potentially more cost-effective alternative to LED for high-intensity applications such as street, area, high-bay, industrial and sports lighting. Induction lamps operate without electrodes, eliminating wiring connections [...]
Sizing Up The Potential of OLED
Below is a reprint of an article about OLED lighting I contributed to the June issue of TED Magazine: Organic light-emitting diode (OLED) is an exciting novel lighting technology. Popular for small-screen display applications such as cell phones, it’s now rapidly developing as a commercial light source. The OLED source consists of organic (carbon-based) thin [...]
A Look at OLED Lighting
Acuity Brands’ video promoting OLED lighting is an interesting take on the technology that transcends the technical and appreciates the light source as an effective tool for enriching spaces with light.
Jim Brodrick on LED PAR38 Lamps
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 PAR38 lamps put in long hours lighting up retail shelves, museum displays, lobbies, and other commercial settings across the country, which presents a prime opportunity to save energy. LED PAR38s, which have [...]
