overexaggerated sustainability1 80% of Architects, Designers Dubious About Sustainability...… Sustainability claims from manufacturers, that is.

A new research study indicates that although the number of environmentally-friendly projects for architects & interior designers is growing, professionals are questioning whether products that claim to be “green” actually live up to the name.

812 architects and designers took part in the survey, sponsored by home & building marketing agency IMRE in conjunction with the AIA (American Institute of Architects) and ASID (American Society of Interior Designers).

Architects, designers, and professionals reading: Weigh in. Is this consistent with your feelings about “sustainable” products from manufacturers? Do you think this is a problem in today’s remodeling and construction industries?

To speak for the lighting industry, this has become a real problem with LED lighting. The market is still maturing for LEDs, and there are a number of products out there that are poorly designed. Sure, they are energy efficient – but energy efficiency carries less weight when a product meant to replace an incandescent, xenon, halogen, or fluorescent light bulb is a fraction as bright as you are accustomed to.

Take caution when selecting LEDs. This issue is one of the reasons we are so careful about ensuring the quality of products we put on the Pegasus Lighting website!

Speed of light The Fastest Thing Known to Man186,000 miles per second.  Wrap your brain around that figure for a moment: Can you imagine traveling at 186,000 miles per second?

The speed of light is a fascinating phenomenon.  Not only is it the fastest thing we can encounter in nature, it’s also one of the most important “constants.”  Remember E=mc²?  “C” represents the speed of light, and that value never changes from 186,000.  Therefore, the speed of light helps determine exactly how much energy (E) is created from a certain amount of mass (m).

It takes about 8.3 minutes for light to travel from the sun to Earth, about 1.2 seconds to get from the moon to Earth and about 100 millionth of one second to get from your floor lamp to the other side of your room.

Waldo Wheres Waldo?  Using LEDs to Stop Oil Damage, Of CourseThe Natural Resources Defense Council and Oceana have launched the most recent plan of attack to protect the Florida Keys from oil plumes, and his name is Waldo.

“Waldo” is a 6-1/2 foot long underwater robot that can detect oil residue in the water and automatically send alerts to researchers, who will, in turn, perform tests and communicate with the local government.

So how does he do it?  As Waldo travels through the water, he sends out ultraviolet light with an LED.  If the water contains oil, it will absorb the LED light and re-emit it.  Any time Waldo detects light emission, he sends a signal to researchers.

Who knew LED lights could ever help with the oil spill?

Just to clarify, white LEDs do not emit infrared or ultraviolet light – that’s why they are useful for art galleries and museums, where this type of light can damage artwork.  However, Waldo does not use white LEDs, which is why he is able to use ultraviolet light to detect oil plumes.

BEAVER FALLS, PA, August 27 — With energy-efficiency gaining in popularity among consumers and businesses, Pegasus Associates Lighting has created a new section on its website dedicated to its energy-efficient lighting products. This new section makes it easier for visitors to find the energy-efficient LED light fixtures, fluorescent fixtures, metal halide light bulbs, and air tight recessed housings that the company offers.

A couple of months ago we posted an article to the Pegasus Associates Lighting website that listed the 10 things to know about LED lighting. Number nine on our list of 10 things to know was OLED.

9. OLED An OLED is an organic light emitting diode.  It is an LED that also contains carbon.  OLEDs are generally manufactured as flexible lightweight sheets.  Today, OLEDs operate at significantly lower efficiency than inorganic (crystalline) LEDs.  OLEDs typically generate less light per area than inorganic, solid state LEDs, which are usually designed for use as point-light sources.

Today I learned that scientists from the independent Stanford Research Institute (SRI) found an innovative design to increase light output and energy efficiency of OLEDs. The answer is cavities. The device that they produced is called, watch out for another acronym, COLED. Yes, the C stands for cavity.

Mercury No Toxic Mercury in LEDsLEDs do not contain any mercury, which makes them less toxic and, therefore, a safer light source to dispose of than 3 of the most ubiquitous light sources used in the world – fluorescent, metal halide, and high pressure sodium light bulbs.
