| | WBDG: Energy Efficient Lighting |
 | | Lamp selection is based on efficacy (lumens per watt), color temperature, color rendering index, life and lumen maintenance, availability, switching, dimming capability, and cost. |
 | | PAR metal halide lamps with ceramic arc-tube enclosures are commonly used for accent lighting and highlighting in large spaces, and are now commonly used in retail applications. |
 | | Incandescent lamps are still used for accent and specialty lighting, where the warm color, controlled brightness, instant-on, and dimming capabilities of these sources is needed. |
