Lighting

With the cost and efficiency of lighting systems ranging widely depending on type and size, it is best to identify how much and what kind of light is really needed for an application and for how long.

 

 
 

Light Emitting Diodes (LEDs)

  • Vastly superior to CFLs in terms of efficiency, dimming, and lumen output
  • Uses 10–20% of the electricity needed for the equivalent light in incandescent
  • Last about 50 times longer than incandescent
  • LEDs dim beautifully, emit hardly any heat, and are cool to the touch

 

 

 

 

 

Compact Fluorescent (CFL) 
  • Typically use about a third or less of the energy that an incandescent uses—a 23-watt CFL can produce about 100 watts of light and runs much cooler while turned on
  • Bulbs also come in a variety of shapes and sizes, and some even come mercury-free

 

 

 

 

 

 

 

 

 

Organic Light Emitting Diodes
  • Made from flexible organic materials that can be placed in almost anything; however, this technology is still in the early stages of development
  • Currently more prevalent in technological applications, such as flexible screens and TVs
Natural Daylight
  • For obvious reasons, the greenest way to illuminate any space
  • Achieved through strategically placed windows and skylights
  • Not every space has the same direct access to the sun
  • Fiber optics can be used to redirect the natural sunlight into unlit spaces
  • Devices known as heliostats can redirect the sun’s rays from outside into your interior spaces
  • Won’t work after the sun goes down
