My contribution to the September issue of ELECTRICAL CONTRACTOR covered lamp- and retrofit kit-based conversions of HID luminaires from HID to LED. With up to 50 percent energy cost savings and potential maintenance savings, LED replacement lamps and retrofit kits offer an increasingly viable retrofit option for HID luminaires. However, products must be carefully matched [...]

I recently had the pleasure of interviewing Alfred LaSpina, LED product group marketing manager, LEDVANCE. The topic: options for upgrading fluorescent troffers to LED.

LEDucation 2018 planning is in full swing and you are invited to share your knowledge and expertise on subjects related to and about LED Lighting. Speaking proposals are due November 19, 2017.

The energy savings potential of networked lighting controls has attracted interest from utilities, prompting the DesignLights Consortium (DLC) to develop a market transformation program that may prove a game changer in the industry.

Espen Technology’s 2X2 and 2X4 VersaKIT LED Flat Panel Retrofit Kits offer DLC listing, even light distribution and a five-year warranty. Featuring Espen drivers and modules, the flat panel retrofit comes completely assembled, utilizes the existing troffer housing to reduce labor time & expense, and can be installed from below the ceiling.

The Illuminating Engineering Society recently announced a new webinar program designed to give members, educators and the general public access to information about quality lighting. The video recordings in the series can be used for IES Section Meetings, as an instructional supplement for introductory lighting courses in post-secondary settings, and for those who are interested in knowing more about lighting.

Solemma is working with sleep scientists at the Alertness CRC in Australian to develop circadian lighting design software geared to architects and lighting professionals. Called ALFA, the software will be demonstrated as a prototype at DIVA Day 2017 on October 27 at the University of California – Berkeley.

With all geographic regions and building project sectors showing positive conditions, there continues to be a heightened level of demand for design services signaled in the latest Architecture Billings Index (ABI). The American Institute of Architects (AIA) reported the August ABI score was 53.7, up from a score of 51.9 in the previous month.

Flicker is an old lighting issue diminished by the mass adoption of fluorescent electronic ballasts and returned with the advent of LED sources. Photometric flicker is the modulation of light source intensity or output over time. Here’s an update on industry efforts to tackle the challenge, with a focus on the recently published NEMA standard.
