Service department lighting offers a great opportunity to increase energy savings and improve overall profitability. Energy efficient building design
practices outlined in the ASHRAE 90.1-2004 standard recommend a maximum power density of 0.7 W/ft
2 for automotive service department lighting
designs. By selecting high performance lighting equipment and incorporating energy efficient light sources, this recommendation is easily achieved.
Cooper Lighting offers a variety of lighting products driven by efficient lamp sources to achieve improved light levels and increased productivity in the
service area while creating energy savings opportunities.
The Metalux F-Bay family of fluorescent high-bays offer dramatic energy savings
opportunities over traditional high intensity discharge systems to provide a quick
return on investment.

NOTES: 1 Total annual cost is the cost of operating 4 fixtures 12 hours per day with a national average energy cost of $0.10 per KWH. Annual Cost = (Input watts)*(# of fixtures)*(operating
hours)*(days/year)*(KWH/1000). 2 Annual Savings is the money saved by operating 4 fixtures for 12 hours per day with the listed source over the standard 400W probe start lamp.
