Case Study - Warehouse
Before the upgrade ...
Making commercial properties more beautiful and safer, one client at a time.
Before Upgrade:400-watt Metal Halide lamps, drawing 480 watts each, with a 2-year useful life
After Upgrade:200-watt Induction Lighting lamps, drawing 212 watts each, with a 22.8 year useful life. The warehouse is more evenly lit with much less apparent glare to the eye.
| Client: | Warehouse facility in Tampa, Florida | |||
| Problem: | This warehouse was using 400w metal halide fixtures that were running at nine hours per day. | |||
| Action: | The warehouse was looking to reduce their energy consumption and provide a better lighting environment for their employees. | |||
| Solution: | Conduct an Energy Savings Assessment showing the owner how he could save as much as 50% every month in energy costs, which would pay for the lighting replacement to Induction Lighting in less than 5 years. | |||
| Project: | Replace the Tampa warehouse’s outdated 100 high-energy metal halide fixtures with Outdoor Lighting Perspectives low energy Induction Lighting fixtures. Additional occupancy sensors were placed on each fixture to further reduce energy consumption. | |||
| Total Energy Reduction | 62% | |||
| Total Annual Savings | $7,086 | |||
| Simple Payback | 4.78 years | |||
After the upgrade ...
Case Study - Parking Deck Re-Lamping
Safety, security and energy/maintenance savings with under a two (2) year payback
Before Upgrade:175-watt Metal Halide lamps, drawing 208 watts each, with a 2-year useful life
After Upgrade:Induction lighting system, drawing 89 watts each, with an 11.4 year useful life based upon the garage’s 24/7 operations.
| Client: | Experian, Schaumburg, IL. | |||
| Problem: | Faced with ever diminishing light levels, replacement of 175W MH lamps every two years and skyrocketing maintenance costs, Experian searched for advancing lighting technology to reduce O&M, and increase security. | |||
| Action: | Experian contacted the lighting manufacturer team partner of Outdoor Lighting Perspectives’ Commercial Outdoor Lighting division– online at SwitchYourLights.co | |||
| Solution: | The team performed economic and engineering analysis of their Induction vs other traditional lighting technologies, participated a competitive long-term demonstration, and provided all support information/data requested. | |||
| Project: | Replaced Experian’s outdated 254 high-energy metal halide fixtures with new low energy/maintenance Induction light fixtures – complete with installation (installation time was less than 15 minutes per fixture). | |||
| Total Energy Reduction | 57% | |||
| Total Annual Savings | $39,387 | |||
| Simple Payback | 32 months | |||
| Payback including incentives | 21 months | |||
|---|---|---|---|---|
| Carbon Footprint Reduction | 1,760 tons of CO2 over 10 years | |||
