MR16 Luminous Intensity: How Does LED Stack Up Against Halogen?

We’ve written here before about one of the toughest problems for manufacturers of LED replacement lamps: achieving light intensity comparable to halogen in the MR16 form factor – particularly for narrow beam distribution. The initial blog post was written in 2014, then updated in late 2016. The update concluded by stating that new breakthroughs in…

Lighting Reference: New Smart Phone & Tablet App from the IESNA

The Illuminating Engineering Society of North America (IESNA) has recently released a Lighting Ready Reference app for smart phones and tablets. Loaded with useful, concise lighting information, this app can be a handy look-up reference for specifiers, electrical contractors, facility managers and educators.   Information included in the app ranges from specification tables to lighting…

LED Fixture Efficacy vs Quality of Light: Recent Study Provides Insights

For several years, the mantra around LED lighting has been the significant rated life and efficacy (lumens/watt) advantage it has over most other light sources. Longer life means fewer bulb changes which translates into reduced maintenance costs for facilities. Better efficacy means lower energy costs. Both of these advantages are quantifiable and allow a straightforward…

Compare Your LED Upgrade Options: A Simple Decision Guide

The savings for commercial buildings and industrial facilities from LED lighting compared to fluorescent and HID are well established – lower energy and demand costs, two to five times longer life and reduced maintenance. However, when it comes to deciding on the best strategy for implementing an LED upgrade, it’s worth taking a close look…

New Study Provides Tools for Evaluating LED vs HID Horticulture Lighting Systems

A recent study by the Lighting Research Center (LRC) at Rensallear Polytechnic provides detailed guidelines for comparing LED and HID light sources for use in commercial greenhouse and other horticulture facilities. The report is also a cautionary advisory on transitioning to LED based only on the criteria of improved energy efficiency and longer lamp life…

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…
