LEDs – the Power to Save Energy!

ImageMore and more home owners and business are turning to energy efficient ideas. LEDs are one of the few technologies today that allow us to have a direct, positive impact on the global environment.

This article “Why LED?” does a good job of explaining how solid state lighting bulbs accomplish these goals - being energy efficient, safe and long-lasting.

  • Facility level payback: eliminates the need for large inventories, reduces the labor associated with lighting maintenance, eliminates the direct cost of labor associated with recycling, saving money on materials and reducing labor associated with installation
  • Safety: no hazardous waste, cool to the touch, no ultra-violet emissions, low voltage power sources or batteries, eliminating the risk of shock
  • Environment: directionality of the light (not into the sky), less carbon dioxide emission into the atmosphere, saving power plants.

  • LEDs hold a "bright" promise, but we are not there yet. I priced a LED wallpack, it was $800, while a similar luminaire in induction was $400. With LEDs, the key is to minimize junction temperature for long life. The life of an LED luminaire is called L70, the point at which the output is 70% of initial. I believe the biggest advantage of LEDs are: Precise control of the light pattern Easy to control No hazardous materials Remember the I-35 bridge in Minneapolis that collapsed? It was rebuilt in less than a year and has Beta LED roadway luminaires. The light levels are comparable to HPS.
