What HID technologies are most efficient for my facility?

For high-ceiling and exterior applications, specify metal halide or high-pressure sodium vapor lamps. In areas you wish to highlight, or accent particular merchandise, use small metal halide spotlights. To learn about HID lighting systems:

• National Lighting Product Information Program Lighting Answers: Mid-Wattage Metal Halide Lamps
  
• National Lighting Product Information Program: "HID Accent Lighting Systems" Report 
  

In some cases, you may be able to reduce the wattage of your already installed HID lamps by purchasing and installing specially designed reduced wattage metal halide lamps. For example, a special 360-watt metal halide can replace a 400-watt metal halide. Consult your lighting professional for more information.
Project Suggestion
Consult your lighting professional about specifying more energy efficient T5 lighting systems instead of HID lighting systems.
