This section contains a summary of §130.0(c) of the Standards as it relates to residential lighting. This information is used to determine luminaire classification for all permanently installed luminaires, and to determine input power in residential kitchens.
The residential lighting Standards require luminaire input power (wattage) to be determined only in kitchens.
There are two different luminaire classifications that need to be considered for complying with residential lighting Standards.
•First, all luminaires, regardless of the type of room in which they are installed, need to be classified as high or low efficacy as described in sections 6.3.2 and 6.3.3 of this chapter. This classification will determine how the luminaire will be treated in §150.0(k) of the Standards.
•Second, if the luminaire is to be installed in a kitchen, the luminaire needs to be classified according to lighting technology in accordance with §130.0(c) to determine luminaire input watts. See sections 6.4.1 through 6.4.8 of this chapter.
If the luminaire is to be installed in a kitchen, luminaire input wattage need to be determined as follows:
•Luminaires need to be labeled in accordance with section 6.4.1 of this chapter.
•Wattage shall be determined in accordance with sections 6.4.2 through 6.4.8 of this chapter (§130.0(c) of the Standards).
The Lighting Standards determine installed lighting power by using the maximum relamping rated wattage of the luminaire.
The Standards require that the maximum relamping rated wattage shall be listed on a permanent, pre-printed, factory installed label, as specified by UL 1574, 1598, 2108, or 8750, as applicable. Labels shall meet the following requirements:
The factory-installed maximum relamping rated wattage label shall not consist of peel-off or peel-down layers or other methods that allow the rated wattage to be changed after the luminaire has been shipped from the manufacturer.
EXCEPTION: Peel-down labels may be used ONLY for luminaires that are manufactured, rated, and designed to meet ALL of the following requirements:
A. The Iuminaire must be one that can accommodate a range of lamp wattages without changing the luminaire housing, ballast, transformer or wiring, and
B. The luminaire can only operate one lamp, and
C. The luminaire has an integrated ballast or transformer, and
D. The peel-down labels shall be layered such that the rated wattage reduces as successive layers are removed and,
E. The luminaire is capable of using only one of the following three lighting technologies:
1. High intensity discharge luminaire, having an integral electronic ballast, with a maximum relamping rated wattage of 150 watts, or
2. An individual low-voltage luminaire (low voltage track systems do not qualify to use this labeling method), ≤ 24 volts, with a maximum relamping rated wattage of 50 watts, or
3. Compact fluorescent luminaire, having an integral electronic ballast, with a maximum relamping rated wattage of 42 watts.
A. The Standards classify all luminaires with line voltage screw-base sockets as incandescent. This includes all types of medium screw base incandescent lamp.
B. For determining input power for incandescent luminaires, use the maximum relamping rated wattage of the luminaire in accordance with the labeling requirements discussed in section 6.4.1 of this chapter.
For recessed luminaires with line-voltage medium screw base sockets, the input wattage shall never be calculated as less than 50 watts per socket, even if the relamping rated wattage on a label is less than 50 watts.
C. Luminaires and luminaire housings designed to accommodate a variety of trims or modular components that allow the conversion between incandescent and any other lighting technology without changing the luminaire housing or wiring shall always be classified as incandescent.
D. Screw-based adaptors are never recognized as converting an incandescent luminaire to any type of non-incandescent technology. Screw-based adaptors, including screw-base adaptors classified as permanent by the manufacturer, are never recognized for compliance with the lighting Standards.
E. Luminaires and luminaire housings manufactured with incandescent screw base sockets shall be classified only as incandescent.
F. Field modifications, including hard wiring of an LED module into an incandescent luminaire or luminaire housing, shall not be recognized as converting the incandescent luminaire or luminaire housing to a non-incandescent technology for compliance with the residential lighting Standards, except for very specific alterations of preexisting luminaires as described in section 6.3.1 E of this chapter. For example, LED lighting modules having incandescent bases, or having incandescent pit-tails, shall not be recognized as LED for compliance with the Standards.
A. Both fluorescent and high intensity discharge (HID) lighting requires ballasts to operate. Therefore, luminaires with installed ballasts are either fluorescent (pin-based linear fluorescent or pin-based compact fluorescent) or HID (metal halide or high pressure sodium).
B. For determining input power for fluorescent and HID luminaires, the input watts shall be the rated lamp/ballast combination used in the luminaire, as published in the ballast manufacturer’s catalogs based on independent testing lab reports as specified by UL 1598.
C. For fluorescent luminaires, this applies only to luminaires that are manufactured, rated, and designed for use with only pin-base fluorescent lamps, Screw-based compact fluorescent lamps do not qualify as fluorescent luminaires.
D. For linear LED lamps, when installed in luminaires that are manufactured, rated, and designed for use with pin-base fluorescent lamps, such LED lamps shall not be recognized as converting the fluorescent luminaire to an LED luminaire.
Track Lighting is a system that includes luminaires and a track, rails, or cables that serve to both mount the system, and deliver electric power. There are two different type of track lighting typically used in residential kitchens: Line-voltage and Low-voltage track lighting.
As shown in Table 6-1, track lighting is always classified as low-efficacy incandescent lighting, regardless what lighting technology is actually installed on the track.
A. Line-Voltage Track Lighting
There is a menu of options available for determining the lighting power of line-voltage track lighting. Following are three options available for determining line-voltage track lighting input wattage when installed in residential kitchen lighting:
1. Use the volt-ampere rating of the branch circuit feeding the track; or
2. Use the higher the following two options:
a. The rated wattage of all of the luminaires included in the system, where wattage is determined according to §130.0(c), or
b. 45 watts per linear foot of track, or
3. When using a line-voltage track lighting integral current limiter, use the higher of the following two options:
a. The volt-ampere rating of an integral current limiter controlling the track or busway, or
b. 12.5 watts per linear foot of track or busway.
Note that only an Integral current limiter that has been certified by the manufacturer to the Energy Commission (§110.9) shall be recognized for determining track lighting wattage. An integral current limiter not certified to the Energy Commission shall not be recognized for compliance with the Standards. See section 6.5 of this chapter for additional information about certification requirements.
B. Low-voltage track lighting
A low-voltage track lighting system is equipped with a remote transformer for use with low-voltage equipment along the entire length of track. The wattage of low-voltage track lighting shall be the maximum rated input wattage of the transformer, as further explained in section 6.4.5 of this chapter.
Low-voltage lighting includes luminaires and lighting systems with permanently installed or remotely installed transformers.
The wattage of low-voltage lighting shall be determined as follows:
A. For low-voltage luminaires that do not allow the 'addition of lamps, lamp holders, or luminaires without rewiring, the wattage shall be the rated wattage of the lamp/transformer combination.
B. For low-voltage lighting systems which allow the 'addition of lamps, lamp holders, or luminaires without rewiring (such as low voltage track lighting), the wattage shall be the maximum rated input wattage of the transformer.
A. LEDs that have been certified to the Energy Commission by the manufacturer as high efficacy are the only LED luminaires recognized being “high efficacy”. LEDs that are not certified to the Energy Commission are automatically classified as low efficacy, regardless of their actual efficacy.
B. For use in residential kitchens, LED wattage shall be calculated using one of the methods below:
1. For stand-alone LED luminaires or light engines (stand-alone means you cannot add LEDs) the installed lighting power shall be the rated wattage of the installed system, when wattage has been determined by the manufacturer in accordance with IES LM-79-08.
2. For LED systems that do allow additional LEDs to be connected without rewiring, the installed lighting power shall be the maximum rated input wattage of the power supply.
3. For luminaires that use LED lamps (either integrated- or non-integrated type) installed lighting power shall be calculated as incandescent luminaires.
4. Luminaires manufactured or rated for use with line-voltage or low-voltage incandescent lamps, into which LED modules or LED lamps have been installed, shall not be recognized as LED lighting systems.
See sections 6.3.7, and 6.9 of this chapter for additional information about residential high efficacy lighting.
This method applies only to lighting systems which have not been addressed by another subsection of §130.0(c), and is primarily intended to address new technologies that have been introduced after the Standards were adopted. This method shall not be applied to incandescent, fluorescent, HID, or LED luminaires because these lighting technologies have already been addressed in §130.0(c).
The wattage of all other miscellaneous lighting equipment shall be the maximum rated wattage of the lighting equipment, or operating input wattage of the system, listed on a permanent, pre-printed, factory-installed label, or published in manufacturer’s catalogs, based on independent testing lab reports as specified by UL 1574 or UL 1598.
In residential kitchens, the installed lighting power of electrical boxes finished with a blank cover or where no electrical equipment has been installed, and where the electrical box can be used for a luminaire or a surface mounted ceiling fan, shall be calculated as 180 watts of low efficacy lighting per electrical box.
