Dear Reader: The buyer of a new LED lighting system engaged in her/his due diligence can be faced with a dizzying array of considerations, and in the interest of time, it’s important to – very early on – separate the noise from the key performance indicators inherent to each device, fixture or system. The operative […]
Lumen Maintenance: How Well a Fixture Holds Its Output Read More »
Dear Reader: Humans spend 90% of their time indoors, a big portion of which under electric lighting. This subjects us to the prospect of physical imbalances, which in turn can make us not only less happy, but less productive. Now, hold that thought. Fact: the sleep aid market has grown an average of 29% annually

Dear Reader: Those fluorescent lamps you’re considering replacing with new LED are a toxic bomb, so we suggest you think carefully about their handling and disposition as you plan out your retrofit project. They’ve got to be handled properly, because improper handling puts your employees and their families – particularly young children – at risk.

Dear Reader: There are a myriad of reasons why our industrial lighting contracting company does what it does, including the altruistic purposes for which we ply our craft. The projects in which we engage inevitably result in energy reductions, which in turn has a positive impact on both human beings and the environment. The Nitric

Dear Reader: The more granular you can make the zoning, the more money your firm will save given reduced energy waste. Cutting the lighting system of a plant into zones can be challenging, but with a few ‘rules-of-thumb’ the task can be made to be much easier. It doesn’t matter how efficient – or inefficient
Group Fixtures Under a Single Control Behavior with Zoning Read More »
Dear Reader: LED fixtures are tested vigorously before being released to the market (see Cameron Miller’s PowerPoint from the National Institute of Standards & Technology), with the object being to measure not only initial lumen output, but to project what that output will be over the course of its useful life. The end of life
Dial the Output Down When Possible with Trimming Read More »
Dear Reader: One of the benefits to be derived from a networked lighting control system lies in its ability to provide for more than one scheduling regime, and that’s important if a Facilities Manager is intent on squeezing every bit of electricity waste out of his/or system. Let’s say Schedule A is your “1st Shift
Schedule Off Times When Production is Down Read More »
Dear Reader: An important feature on many lighting controls systems is the ability to gradually ramp up the amount of lumen output of a fixture when a person enters a work space area, rather than a hard, harsh jump to ‘On’. Conversely, the use of this as a strategy might be deployed on the back
Eliminate Harsh On and Offs with Ramping and Fading Read More »
Dear Reader: Virtually all Facilities and Energy Managers are aware of the value of occupancy sensors used in conjunction with LED luminaires, but some might benefit from an enhanced understanding of how to adjust the settings to optimize their lighting system’s ability to lower energy consumption without compromising the illuminating qualities of each fixture within
Use Occupancy Sensors to Detect People Read More »
Dear Reader: On/off, stepped switching, stepped dimming, or continuous dimming .. which approach does the Facilities Manager select? The answer depends on what type of area is being illuminated, and how the Manager wants the fixtures to behave over various, changing operating conditions. Reference PNNL’s Dimming LEDs with Phase-Cut Dimmers for help in this regard.
