Service areas include closets, laundry rooms, utility rooms, workrooms, unfinished basements, and garages. Service areas should be the first step in any approach to high performance lighting. Because of their utilitarian nature, service areas benefit from the simplest level of direct lighting with surface mounted fixtures. Though the frequency and length of use of these rooms may not be high, it is common for occupants to leave these lights on and often unattended for long periods, so the efficiency of HPL can provide significant value in reducing lighting energy costs.
The lighting in these rooms often serves as task lighting, as well as ambient. Thus, it provides somewhat higher levels of illumination than ambient lighting criteria alone would require. It is recommended that you use 830 (80 CRI, 3000K) lamps (Specification of Bulbs and Lamps) even in these utilitarian spaces for consistency with HPL in other rooms and with incandescents. It is particularly important to use these lamps for closet lighting, so that clothing colors appear accurately. Selecting recessed lighting for closets will provide a crisp, dramatic illumination of clothes. In laundries and other workrooms where cabinetry is mounted above counter surfaces, the use of undercabinet lighting is recommended for good task illumination. The high quality of light provided by indirect lighting is typically considered unnecessary for service areas.
