When are LEDs (Solid State Lighting) going to be a reasonable purchase?

          A reasonable purchase is defined by the intent of the owner or his/her agent(s). For them to be able to make valued judgements, it is the responsibility of the lighting designer to present a full analysis of the benefits and detriments of LEDs for each particular application. Accent, spot, cove and wall washing make excellent choices.

          aeonlighting.com_office.jpgAttention must be given to atriums, outdoor facades, walkways, gardens and parking lots as being particularly desirable for a lighting upgrade. White light can be provided where see-ability is prime. This would include roadway approaches and new construction.

          On the left is the Aeon office reception area designed with white-spectrum lighting, plus blue accent lighting on the desk and counter. Selected LED colors are 'cool' as in cool-white (but cooler). Different from other designs, this modern office is enhanced by choosing cooler-whites. The enhacement enables brighter illumination at lower wattages and makes for efficient work production as well as improved readability.

           Cree, who claims to be a leader of the LED Lighting Revolution finds that many of you are in the dark when it comes to energy efficient LED lighting. As designers, we bring your "Perception to Light".

          Cree suggests ''you may have to change your mind set about about lighting and LEDs in general." Also, they feel that for a long time you said LEDs were not a viable source for general lighting. As an engineer I agree, but realize that the pleasure of the client prevails after the facts for his/her decisions are clear. This is most adequately demonstrated  by clients with identical applications who are close to 50/50% when it comes to their perception of color. About half choose toward the orange end of the visible spectrum and half choose toward the blue-white end. This disregards those whose preference is toward the middle of the spectrum.

          Some choices are without regard to color schemes and preferred highlighting. The clients perception is reviewed at this point to assure the desired color coordination. Because of the vibrance of LEDs, appropriate color enhancement or de-emphasis becomes a nice ambiance choice.

          For those desiring earlier information, request our article "LED Lighting 101" to follow where LED lighting has already been successfull. More recently, LEDs have been the backlighting for televison sets, monitors and cell phones - plus illumination of automobile directionals, tail lights and interiors.

          We also agree with Cree that LEDs require up to 85% less electricity than incandecents and up to 50% less, than some fluorescemts. More than that, as Cree claims, "LEDs are capable of producing beautiful light". That beautiful light is now all-over. Most clients want something LED. We often are told, "I want to try some". Indoor and outdoor (in-ground and or cement) LED step/walkway lighting is a present leader, the motivators being safety and low electrical consumption.

          We are lighting designers who replicate perception. If you have not finalized an up-to-date energy-saving-efficiency design your wire may not be installed in the approriate places, nor will you be able to save wire, circuits and installation costs. Remember, most of our clients do not usually put those installation savings in their pocket, but request energy-saving controls and schemes, the electricity savings from which will line their pockets even more handsomely.

          Our key to quality fixtures and light-bulbs is DOE (U.S. Dept. of Energy) testing. Particularly, LM79 and LM80.
