For incandescent applications, one HSL unit displaces 8,000 kWh per year. - At $0.10 per kWh, can save $8,000 over 10 years - Operation and maintenance savings could add another $2,500 - For floor-spaces of 100,000 to 200,000 sq.<br><br> ft., this translates into $1.1M to $2.1M of energy cost savings IncandescentFluorescentHSL Typical Energy Eff.
