Legislation Details

California Title 20 regulates the sale of any 150-500W metal halide product between after December 31, 2009, unless stringent energy requirements are satisfied.

Legislative details:

The scope covers indoor and outdoor luminaires with lamps rated 150-500 watts.

An indoor metal halide luminaire must:

by 1/1/2010 utilize one of the following features

use a high-efficiency ballast (90% for 150-250 watts or 92% for 251-500 watts) OR
use an 88% ballast efficiency and an integral control occupancy sensor that reduces the lamp power by a minimum of 40% within 30 minutes after an area is vacated OR
use an 88% ballast efficiency and an integral control for automatic daylight sensing that reduces the lamp power by a minimum of 40% OR
use an 88% ballast efficiency and a reduced wattage lamp. The luminaire must incorporate a factory-installed relamping label corresponding to appropriate lamp watts.
- 150-160 watts
- 200-215 watts
- 290-335 watts
- 336-500 watts – lamp must be a minimum of 80 MEAN lumens per watt and must be shipped with the luminaire

by 1/1/2015
1. use an 88% ballast efficiency and a reduced-wattage lamp. The luminaire must incorporate a factory-installed relamping label corresponding to appropriate lamp watts.
  - 150-160 watts
  - 200-215 watts
  - 290-335 watts
  - 336-500 watts – lamp must be a minimum of 80 MEAN lumens per watt and must be shipped with the luminaire

AND at one of the following features:

use a high-efficiency ballast (90% for 150-250 watts or 92% for 251-500 watts) OR
use an 88% ballast efficiency and an integral control occupancy sensor that reduces the lamp power by a minimum of 40% within 30 minutes after an area is vacated OR
use an 88% ballast efficiency and an integral control for automatic daylight sensing that reduces the lamp power by a minimum of 40%

An outdoor metal halide luminaire must:

by 1/1/2010 MAY incorporate an 88% ballast efficiency and an integral control for automatic daylight sensing that reduces lamp power by a minimum of 40% and SHALL utilize one of the following features

use a high-efficiency ballast (90% for 150-250 watts or 92% for 251-500 watts) OR
use an 88% ballast efficiency and an integral control occupancy sensor that reduces the lamp power by a minimum of 40% within 30 minutes after an area is vacated OR
use an 88% ballast efficiency and a reduced wattage lamp. The luminaire must incorporate a factory installed relamping label corresponding to appropriate lamp watts.

150-160 watts
200-215 watts
290-335 watts
336-500 watts – lamp must be a minimum of 80 MEAN lumens per watt and must be shipped with the luminaire

Exceptions to the above:

The following metal halide lighting systems shall not have probe-start ballasts and are not required to meet the minimum ballast efficiency requirements:

Luminaires that use regulated lag ballasts; or
Luminaires that use electronic ballasts which operate at 480 volts; or
Luminaires that meet all three of the following requirements:
- Are rated for use only with 150 watt lamps, and
- Are rated for use in wet locations, as specified by the National Electrical Code 2002, Section 410.4(A); and
- Contain a ballast that is rated to operate at ambient air temperatures above 50 degrees C, as specified by UL 1029-2001.
