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, which must be
				minimum 60 lumens/watt.
BLL = For luminaires incorporating a ballast or transformer,
				the rated input wattage of the ballast or transformer when operating the
				lamp.
TRK = For lighting track, cable conductor, rail conductor and
				plug-in busway systems that allow the addition and relocation of lu-minaires
				without rewiring, the wattage shall be one of the following:
1. The specified wattage of the luminaires,
			 but not less than 16 W/lin. ft. (52 W/lin. m).
2. The wattage limit of the permanent current
			 limiting devices protecting the system.
3. The wattage limit of the transformer
			 supplying the system.
POE = For other modular lighting systems served with power
				supplied by a driver, power supply for transformer including, but not limited
				to, low-voltage lighting systems, the wattage of the system shall be the
				maximum rated input wattage of the driver, power supply or transformed
				published in the manufacturer's catalogs, as specified by UL 2108 or 8750. For
				power-over-Ethernet lighting systems, power provided to installed nonlighting
				devices may be subtracted from the total power rating of the
				power-over-Ethernet systems.
Other = The wattage of all other luminaires and lighting,
				sources not covered above 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 is not included in calculating total connected lighting power.
