Incandescent Lamp Obituary
By Dale Roethlisberger

The run of the incandescent lamp has lasted over a century. With the passage of the Energy Act of 2007, U.S. manufacturers of lamps for lighting fixtures will begin the process of phasing out incandescent lamps by the year 2012. The reasons for the demise of incandescents are strong. Technological obsolescence in the case of incandescents means vast energy savings in regular usage of compact fluorescent lamps or even better, light emitting diodes. The manufacturers of lamps are reluctant to admit the huge increase in lifetimes as well. Let’s face it, manufacturers of lamps have a vested interest in selling the public ever more lamps. Long lasting lamps might put a dent in recurring replacement sales. Read the rest of this entry »

“New Lamps for Old”, the Tale of Aladdin and His Magic Lamp (Revised for 2008)
By Dale Roethlisberger

Most of us know some version of the story of “Aladdin and His Magic Lamp”. The most important point in the story is that there is a ‘djinn’ (i.e. genie) living in his lamp. Today, we have genie’s living in some of our modern electric lamps. Arthur C. Clarke, author of “2001: A Space Odyssey”, once said, “any highly advanced technology is indistinguishable from magic”. Compact fluorescent lamp (CFL) and light emitting diode (LED) replacement lamps are that kind of “technological magic”. You don’t have to know how it works, but both the economics and the environmental benefits of switching to CFL’s and LED’s are the future until something even more advanced is developed.

For example, while it may cost you twice or more to initially purchase a compact fluorescent lamp, that CFL will generally last 7 to 8 times longer than an incandescent lamp, and will use 1/3 to 1/5 the electricity for each hour of operation. We’ll leave you to do the math. Read the rest of this entry »

Everything Seen or Done Has Photonic Elements
By Dale Roethlisberger

This web-site will ultimately be about environmentally sound lighting technology solutions for both commercial and residential applications. We must make some statements of principles before we proceed with our primary mission. The phenomina of ‘light’ in the science of physics is mostly referred to as photonics. In fact, almost everything on the planet Earth has been somehow modified by the derivative photonic effects of sunlight. All the energy used by mankind is derivative of either the sun’s direct input of photonic energy over billions of years (i.e. fossil fuels) or as a result of the immense gravity of the sun as the principle organizing force to the solar system. For example, the sun’s gravity well is the principle force behind the collection of all materials that comprise the Earth, including raw nuclear materials that can be used to generate nuclear power.

The Sun’s direct photonic input to the Earth has far reaching consequences to our daily lives. Our weather, the planet’s biosphere, the storing of fossil fuels energy over billions of years, and countless other examples are directly related to the daily flood of solar photonics. More importantly, without the Earth’s ability to moderate this energy flow in numerous mechanisms, we wouldn’t be here. Without our magnetosphere, it is unlikely that much of the biosphere would ever have developed. Read the rest of this entry »
