Cost over lighting system life:
Cost per 1,000 hours:
Cost per year:
Cost per million lumen hours:
Savings with Lighting System 2:	/year

*If you are comparing lighting systems with significantly different light output, the cost per year may have a greater difference. To get a more accurate representation of the cost of light, look at the cost per million lumen hours.
