Lighting Distribution Types Provide Key Information When Selecting Roadway Fixtures

Effective illumination of streets and roadways requires consideration of many factors. These include: sufficient light levels to allow easy identification of other vehicles, people and objects; control of light distribution to optimize for the target area and minimize stray light; uniformity of light; adequate contrast; and minimal glare. In addition, other factors such as efficacy…

Study Provides Key Insights on LED T8 Replacements for Strip, Wrap and Pendant Fixtures

LED T8 replacement lamps for existing fluorescent T8 linear tubes have emerged as a priority consideration for facility managers in office, school, warehouse, hospital/medical, restaurant, grocery and other applications. The promise of significant energy savings and lower maintenance costs, plus the relative simplicity of most LED replacement projects, has motivated this interest. In addition, on…

Planned Maintenance Integral to the Long Term Benefits of LED Lighting Systems

An easily overlooked factor to consider when making lighting decisions for commercial installations is maintenance. Most decisions focus on the lighting technology – T8 fluorescent vs T8 LED or occupancy sensors vs timer controls for example. Equally important is thinking through new maintenance protocols or staff training that may be called for when installing new…

Lighting Uniformity: Study Shows An Important Advantage of LED Fixtures for Parking Lots

One of the fastest growing segments of the LED commercial lighting market is site, area, street and parking lot lighting. Owners of commercial property and municipalities in particular are looking at LED solutions for new developments or to replace HID fixtures in existing applications. In this post we will look at occupant perceptions of safety,…

Evaluating an LED Retrofit of HID High Bay Fixtures in a Maintenance Facility

The Lighting Research Center (LRC) at Rensselaer Polytechnic Institute has conducted a field research project evaluating installation issues and performance of a high bay retrofit where the existing metal halide bulbs have been changed to LED. High bay fixtures that use metal halide lamps in warehouses, shops, sports facilities and big box retail offer an…

How to Make Sure Photocontrols Are Compatible With LED Lighting

Photocontrol devices use photocells to determine ON/OFF status of outdoor lighting based on the ambient light level. While generally understood as responding to visible light, some photosensors also respond to infrared (IR) and ultraviolet (UV) radiation. Normally used for roadway, area, parking, flood and security lighting, photocontrols automatically control the ON/OFF cycle to optimize the…
