Four New Technologies Offer Potential for Lighting

My contribution to the December 2013 issue of ELECTRICAL CONTRACTOR describes four interesting lighting technologies that offer a new potential for lighting. Field-induced polymer electroluminescent, quantum-dot LED, visible light spectrum communication, and bioluminescent illumination. Check it out here.

ELECTRICAL CONTRACTOR Publishes Article on LED Maintenance

My lighting column in the April 2013 issue of ELECTRICAL CONTRACTOR addresses LED product maintenance. Over the past months, I’ve had the opportunity to work with the IES Maintenance Committee on revising RP36, and conducted extensive interviews with manufacturers and others about maintaining LED products. As you might suspect, they’re not quite maintenance free. Click [...]

ELECTRICAL CONTRACTOR Publishes Article on Light Right Survey Tool

ELECTRICAL CONTRACTOR recently published a lighting column I authored on the topic of the Light Right Survey Tool, available here. Developed by the Pacific Northwest National Laboratory, it enables building owners/managers and lighting practitioners to inventory and evaluate lighting systems in office spaces. Available free, the Light Right Survey Tool can be used: • As a [...]

ELECTRICAL CONTRACTOR Publishes Article About Light and Color

Lighting choices can affect how we perceive spaces, even the colors of objects and surfaces. As a result, lamp color characteristics are a critical factor in a wide range of spaces, from high-end retail, where merchandise must be presented as vibrant and in its true colors, to offices, where good lighting renders faces naturally and [...]

Lighting Rebates Enjoying Upswing

Rebates and incentives offered by electric utilities and regional energy-efficiency organizations are currently enjoying a major upswing, providing a significant resource that can reduce the cost of investing in energy-efficient lighting. According to the Consortium for Energy Efficiency (CEE), energy-efficiency rebate and incentive programs reached $6.8 billion in 2011, up 26% from 2010 ($5.4 billion) [...]

ELECTRICAL CONTRACTOR Publishes Article on Bilevel Stairwell Lighting

Stairwell lighting is typically operated continuously at full output in nonresidential buildings even though these spaces are only intermittently used. In recent years, lighting manufacturers have begun offering a control solution that can reduce energy costs while providing satisfactory levels of illumination for emergency egress. These lighting fixtures automatically adjust light levels based on occupancy. [...]

Electrical Contractor Magazine Publishes Article About Model Lighting Ordinance

The Model Lighting Ordinance (MLO), produced jointly by the Illuminating Engineering Society (IES) and the International Dark-Sky Association (IDA), provides a template for municipalities seeking to develop standards for responsible outdoor lighting. Specifically, the MLO addresses skyglow (light emitted up into the sky that obscures nighttime viewing of stars), light trespass (light emitted onto neighboring [...]

ELECTRICAL CONTRACTOR Publishes Article About Electrodeless Lighting

Electrodeless lamps do not require wiring connections between the lamp and its ballast or driver. As most wear and tear on lamps occurs at the electrode, its absence in this technology can significantly extend lamp life. This article I wrote for ELECTRICAL CONTRACTOR breaks down the different types, from induction lamps to plasma lamps. Not [...]

The End of The T12 Era Approaches

By now, the electrical industry is well aware that national energy standards have eliminated the manufacture and import of fluorescent magnetic ballasts for 4- and 8-foot standard and energy-saving T12 lamps, with few exceptions. On July 14, 2012, Department of Energy (DOE) rules regulating general-service fluorescent lamps will go into effect, eliminating many popular models [...]

How to Evaluate Light Sources

Electrical Contractor recently published an article I wrote about a simple methodology for evaluating light sources based on a basic series of questions: • What is the distribution of the light? Distribution is measured in candelas (cd). • How long does the lamp last? Service life is measured in hours. • How much light does [...]
