We see more and more light sources that have a reported/indicated colour temperature that when compared to another light source actually appear different to human eye. So, how and why does this happen? When discussing colour temperature (CT), people are usually referring to correlated color temperature (CCT). There is a key difference between these two...

An interesting concept to be sure, having not yet seen this in actual use, I cannot comment on how robust the mechanism is, nor on how long the battery will last. Lighted Door Handle Concept
Light-emitting diodes, or LEDs, once were the stuff of electronics geeks rifling through circuit board component drawers at Radio Shack. They were the blinking lights on computers and stereo systems signifying that the power was on, and the soft red glow of a calculator display back when President Jimmy Carter was putting solar panels on...

Castle Howard Case Study: Planetsaver 2013 Although this is a British case, the basic elements of the retrofit story are the same for the North American and particularly Canadian market. Re-lamping (changing out old technology bulbs such as incandescent, halogen or fluorescent) your light fixtures with LEDs is the simplest, quickest and easiest way to...
Here’s a link to an interesting article on residential retrofits and how to properly incent homeowners/consumers. It is written for the British, but applies equally here in North America. http://www.theguardian.com/sustainable-business/light-bulbs-incentives-energy-efficient Things we consider when we move a client from a traditional lamp/bulb to LED: an LED need only provide 1/7th the output (in watts) of...

A very interesting article on the immediate impact of retrofitting to LED. Although the discussion starts at the public policy level with a mention of POTUS Obama’s state of the union speech, it quickly drills down to the nuts and bolts of large multi-location commercial retrofit. Long story, short: this can be done today, it...
Yesterday I wrote briefly about financing for retrofit projects, presenting one point of access for capital, an innovative municipal government program. Today I will present a second option, which is a lease program offered by a private company on a for-profit basis. This concept is relatively unique, as leasing of lighting has rarely been done...
