C405.3.1 Total Connected Interior Lighting Power
JUMP TO FULL CODE CHAPTER
The total connected interior lighting power shall be determined in accordance with Equation 4-10.
TCLP = [LVL + BLL + LED + TRK + Other]
(Equation 4-10)
| where: | ||
| TCLP | = | Total connected lighting power (watts). |
| LVL | = | For luminaires with lamps connected directly to building power, such as line voltage lamps, the rated wattage of the lamp. |
| BLL | = | For luminaires incorporating a ballast or transformer, the rated input wattage of the ballast or transformer when operating that lamp. |
| LED | = | For light-emitting diode luminaires with either integral or remote drivers, the rated wattage of the luminaire. |
| TRK | = | For lighting track, cable conductor, rail conductor, and plug-in busway systems that allow the addition and relocation of luminaires without rewiring, the wattage shall be one of the following:
|
| Other | = | The wattage of all other luminaires and lighting sources not covered previously and associated with interior lighting verified by data supplied by the manufacturer or other approved sources. |
The connected power associated with the following lighting equipment and applications is not included in calculating total connected lighting power.
- Television broadcast lighting for playing areas in sports arenas.
- Emergency lighting automatically off during normal building operation.
- Lighting in spaces specifically designed for use by occupants with special lighting needs, including those with visual impairment and other medical and age-related issues.
- Casino gaming areas.
- Mirror lighting in dressing rooms.
- Task lighting for medical and dental purposes that is in addition to general lighting and controlled by an independent control device.
- Display lighting for exhibits in galleries, museums and monuments that is in addition to general lighting and controlled by an independent control device.
- Lighting for theatrical purposes, including performance, stage, film production and video production.
- Lighting for photographic processes.
- Lighting integral to equipment or instrumentation and installed by the manufacturer.
- Task lighting for plant growth or maintenance.
- Advertising signage or directional signage.
- Lighting for food warming.
- Lighting equipment that is for sale.
- Lighting demonstration equipment in lighting education facilities.
- Lighting approved because of safety considerations.
- Lighting in retail display windows, provided that the display area is enclosed by ceiling-height partitions.
- Furniture-mounted supplemental task lighting that is controlled by automatic shutoff.
- Exit signs.
