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…

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…

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…
