Frequently Asked Questions

LEDs are typically for 50,000 hours of life, with some external driver options lasting as long as 80,000 hours. Incandescent and halogen lights often have a 2,000 hour lifetime, with fluorescent and high pressure sodium lights lasting potentially as long as 15,000 hours. The increased lifetime of LED technology allows users to enjoy reproduced maintenance and replacement costs that would normally be endured by constantly replacing traditional lighting.

LED stands for Light Emitting Diode, a technology that has been around since the 1950’s and has long been known as an extremely efficient light source. Recent developments in LEDs now allow them to be used in environmental and task lighting. LEDs have many advantages over incandescent light sources including lower energy consumption, longer lifetime, improved physical robustness, smaller size, and faster switching. LEDs contain no mercury and are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness.

The energy reduction will vary depending on the existing lighting in place, but most often clean energy LEDs will reduce lighting cost by 50-90%. Many LED upgrades yield ROIs within three years of installation, making them one of the most financially substantial green investments available.

The layers of phosphor on the LED dictate the color temperature, therefore an enormous range of colors can be produced. The most commonly used color temperatures are measured in Kelvin and consist of 3000K (Warm), 4100K (Neutral), and 5000K (Cool). Conventional LEDs are made from a variety of inorganic semiconductor materials and vary with wavelength range, voltage drop and material. Colors range from Infrared to White (and include Red, Green, Purple, Pink, plus others).
