Mandatory requirements for sign lighting are specified in +. The mandatory requirements include control device, control installation, and system functionality requirements. Mandatory features also set requirements for how lighting systems are classified according to technology, and how to calculate installed wattage.
All installed lighting control devices and systems must meet the functionality requirements in § 110.9(b)|topic=(b) All Lighting Controls.. In addition, all components of a lighting control system installed together shall meet all applicable requirements for the application for which they are installed as required in §130.0 through §130.5, §140.6 through §140.8, §141.0, and §150.0(k).
The person who is eligible under Division 3 of the Business and Professions Code to accept responsibility for the construction or installation of features, materials, components, or manufactured devices must sign and submit an installation certificate before a lighting control system, including an energy management control system (EMCS), can be recognized for compliance with the lighting control requirements in the Energy Code (§130.4(b)|topic=SECTION 130.4 –LIGHTING CONTROL ACCEPTANCE AND INSTALLATION CERTIFICATE REQUIREMENTS. 1 and 2).
Designers and installers should review features of their specified lighting control products for compliance with §110.9(b)|topic=(b) All Lighting Controls. as part of the code compliance process.
Time-switch lighting control products must provide the functionality listed in §110.9(b)1|topic=(b) All Lighting Controls..
Daylighting control products must provide the functionality listed in §110.9(b)2|topic=(b) All Lighting Controls.
Dimmer products must provide the functionality listed in §110.9(b)3|topic=(b) All Lighting Controls.
Occupant-sensing control products must provide the functionality listed in §110.9(b)4|topic=(b) All Lighting Controls. and §110.9(b)6, and must automatically reduce lighting or turn the lighting off within 20 minutes after the area has been vacated.
§130.0(c)|topic=(c) Luminaire classification and power.
Luminaire power must be determined in accordance with the applicable provisions of §130.0(c)|topic=(c) Luminaire classification and power.. Note that the installed wattage of sign lighting is not considered when using the Alternate Lighting Source compliance option in §140.8(b). See Section 7.4 of this chapter for more information about sign lighting energy requirements.
These are the requirements for determining luminaire power:
1. The wattage of luminaires with line voltage lamp holders not served by drivers, ballasts, or transformers shall be the maximum rated wattage or relamping-rated wattage of the luminaire as labeled in accordance with §130.0(c)1|topic=(c) Luminaire classification and power..
2. The wattage of luminaires with permanently installed or remotely installed ballasts shall be the operating input wattage of the rated lamp/ballast combination published in the ballast manufacturer’s catalog based on independent testing lab reports as specified by UL 1598.
3. The wattage of luminaires and lighting systems with permanently installed or remotely installed transformers shall be the rated wattage of the lamp/transformer combination.
4. The wattage of LED luminaires and LED light engines shall be the maximum rated input wattage of the system when tested in accordance with UL 1598, 2108, or 8750, or IES LM-79.
5. The wattage of LED tape lighting and LED linear lighting with LED tape lighting components shall be the sum of the installed length of the tape lighting times its rated linear power density in watts per linear feet, or the maximum rated input wattage of the driver or power supply providing power to the lighting system, with tape lighting tested in accordance with UL 2108 or 8750, or IES LM-79.
The rules for determining lighting wattage are discussed in greater detail in Chapter 5 of this manual.
