LED lighting is continuing to grow. Access Fixtures reports LED products sales are up 220% year over year compared to the first half of 2013.
While the price of LED lighting is decreasing, LEDs are simultaneously advancing in energy efficiency, light output, module life, and versatility. The rapid progression of LED lighting is known as Haitz’s Law. Every decade, the cost per lumen (lumens are the unit of useful light emitted) falls by a factor of ten while the amount of light generated per LED package increases by a factor of twenty. Therefore, LEDs are becoming a reasonable and cost-effective option when considering alternatives to incandescent, HID, and fluorescent light sources.
LED lighting provides a significant return on investment, but its biggest draw is arguably its energy efficiency. For example, today’s ten-watt LED bollard lights can outperform a seventy-watt, high-pressure sodium bollard light. LED wall packs can exceed the performance of 100-watt metal halide wall packs using less than half the energy.
