The lumen’s limits: why old measures of light output don’t always work for LEDs, and what to do about it

When replacing one light source with another, you need a medium of exchange, and lumens exist to serve as that medium. However, LEDs may be the end for the old faithful lumen. In practice we’ve found it to be a significantly inaccurate indicator of brightness where LEDs are concerned.

On the “rebound effect” in energy efficient lighting or why LEDs aren't like other energy efficiency

On the “rebound effect” in energy efficient lighting or why LEDs aren't like other energy efficiency

Will LEDs, a technology that creates more light per unit of electricity than any commercial technology before it, increase demand for electricity? Will an efficiency technology increase overall consumption?

From floor plan to lights on—LEDs in new construction

From floor plan to lights on—LEDs in new construction

As LED products evolve, building efficiency codes tighten, and the mental hurdle created by having to change something already in place is removed, owners and general contractors working in new construction are raring to go with LED lighting.

Lights out—the practical life expectancy of LEDs

Lights out—the practical life expectancy of LEDs

How long will a good LED bulb last in a commercial environment? There are so many products and variables, and many possible answers, so let’s lead with our professional opinion: 2-3 years.

Acknowledging that this is a complex and on some level impossible question to answer, here we will explain how we approach life expectancy in our LED fleet.
