LEDs cost more than conventional lights, but they are more energy efficient and also have a longer operating life than most comparable conventional lights, thus saving on operating, maintenance, and replacement costs.  Many applications with LEDs have a fairly short payback period.  For example, Sunlite’s LED replacement for a T-12 fluorescent light typically pays back in two years.  Depending on the application and product type, some LEDs actually pay for themselves immediately.  Sunlite’s LED Can lights do not cost more than traditional can lights.
