When considering lighting technologies it is extremely important to look at the true lifecycle cost of your lighting investment.  The plot below shows that LED technology (Blue lines) provides the most long term value as compared to metal halide (Red line), fluorescent (Orange line), or induction (Yellow line).  This data takes into consideration acquisition cost, labor, lamp cost, ballast cost, re-lamping, re-ballasting, inflation, technology cost factors over time, annual maintenance, and energy usage. 

Simply stated, LED lighting technology is the best long term financial choice because it lasts 4 to 5 times as long as metal halide, high pressure sodium, and fluorescent.  The LED advantage comes from the savings combination of the near elimination of maintenance costs, and the reduction of energy consumption by 65% to 85%. 

The LEDs we use in our products are rated at 100,000+ hours (dark blue line)  The typical light degradation of an LED by 30% occurs at 50,000 hours.  Most customers will not replace a perfectly good LED at 50,000 hrs if it is still putting out 70% of its light, but the data point has been plotted for reference (light blue).

In addition to providing the best long term value LED also is a superior technology in many non-cost related categories.
