LED Lighting and Power Quality: The High Cost of Ignoring Power Quality Issues When Switching to LED

  The effects of power quality on LED lighting performance generally receive little attention prior to installation for most commercial applications. Power quality issues such as dips, harmonics, interruptions, transients and surges can result in expensive, early replacement of damaged or failed LED lighting equipment. While facility managers involved with smaller commercial projects may be…

DesignLights Consortium (DLC) Qualified Product List Benefits Buyers and Utility Incentive Programs

  Since 2010, the DesignLights Consortium (DLC) has been qualifying commercial sector LED lighting products and publishing a list – the Qualified Products List (QPL) – that meet specific performance requirements. These key performance metrics, updated to keep pace with both the evolution of LED technology and the needs of utility and industry stakeholders, are…

LED Troffers Offer Strong Case To Replace Fluorescent

Fluorescent troffers in North America account for nearly 50% of all fixtures installed in commercial buildings such as office, retail, education and medical facilities. Troffers normally are installed in T-bar grid drop ceilings with the 2 ft. x 4 ft. configuration being the most common. In 2018, LED troffer fixtures and troffer retrofit kits deliver…

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…
