• HID is generally the most efficient light source
• Better efficiency almost always means lower operating cost
• Most HID lamps have life ratings that are better than incandescent lamps and similar to fluorescent lamps
• An HID lamp produces high light output from a relatively compact source
• Like incandescent, it is a point light source, which allows for good optical control
• Phosphor coated deluxe lamps provide good color rendering
• GE light bulbs are built to last, so you can replace them and forget about them
