SoLux™ Daylight Lamp Cost Justification

Estimated Savings Using SoLux Instead of PAR lamps

Based on a installation of only 100 lamps, SoLux can save you per year over $7,000 in maintenance and electricity costs.  This calculation compares lamps with the same beam spreads for accuracy. This analysis clearly demonstrates the immediate cost savings realized by substituting outdated PAR lamps with energy efficient, long life, SoLux daylight lamps.
