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…

How to Read Outdoor Fixture Light Distribution Classification Systems

light distribution from street lights

Fixtures can be categorized by application, mounting, light source, construction and light distribution. In this post, the focus will be on light distribution. For lighting specifiers and contractors, it’s important, particularly for outdoor fixtures, to know the light distribution pattern and characteristics of the distribution. The shape (as well as brightness) of the area that…

Key Concepts to Consider When Upgrading Lighting for Warehouse Rack Storage Areas

    Warehouses using rack storage systems present unique lighting design challenges particularly for retrofits intended to improve the lighting scheme. The layout of most product storage warehouses comprises a shipping and receiving area (may be the same or separate areas), a low, open storage area for bulky items and a high rack storage area,…

LED Upgrades Often Make Sense for Small Retail
