The Opportunity:
The client sought to reduce energy costs and increase light levels in various high energy locations across the country. The existing systems were 400W metal halide hi-bays. The company recognized the opportunity to achieve a number of lighting quality improvements while reducing their bottom line and committed to completing an energy audit once the project roll out was complete.
The Solution:
HID technologies were completely retrofitted to six lamp T8 fluorescent fixtures. In addition the extended manufacturer warranty offered through Illumetek made the entire retrofit a “no cost” maintenance upgrade for the first three years of the project installation.
Results:
Work was completed on schedule and the utility bills were evaluated for reduced electric utility expenses and kWh usage. Table 1 shows data acquired from actual utility bills.
