WHAT HAS CHANGED SINCE TITLE 24 2013?


ALL HIGH EFFICACY LIGHTING
Indoor and outdoor lighting for new homes must be high efficacy.

SIMPLIFIED CONTROL REQUIREMENTS
Lighting control requirements for indoor spaces are now simpler. Control requirements are based, in nearly all cases, on the type of lamp or luminaire installed, not the space.

JA8 UPDATED
Joint Appendix 8 defines the performance requirements for high efficacy LED sources and requires that LED sources provide 90+ CRI illumination and a R9 value of >=50 (both of these metrics equate to lighting that is more pleasing in residential applications). LED sources must also now meet strict requirements for reduced flicker, <30% both at 100% and when dimmed to 20%.

HOW DO I KNOW WHICH PRODUCTS MEET TITLE 24 2016?


HIGH EFFICACY LED, MEETS JA8-2016

Any fixture with a screw base socket complies with Title 24 when a JA8 listed light bulb is installed. The light bulb must be marked either as: JA8-2016 or JA8-2016-E. The E indicates the bulb has been tested and meets requirements established for use in enclosed fixtures (ex: flush mounts)
*Note: Recessed downlights may not have a screw base socket regardless of lamp type.
Any fixture that has an Integrated LED that has been tested and listed in the California Appliance Database. Check for certified bulbs or fixtures by searching the MAEDBS database.

HIGH EFFICACY LED, NOT REQUIRED TO MEET JA8

Table 150.0A defines products that do not have to meet JA8, the most common types include:

  • • Pin-based linear or compact fluorescent light sources using electronic ballasts
  • • GU-24 sockets containing light sources other than LEDs
  • • Inseperable SSL luminaires that are installed outdoors

CONSTRUCTION & INSPECTION
The builder must now provide new homeowners with a schedule that includes a list of installed lamps and luminaires.
OUTDOOR CONTROLS
For single family homes, lighting mounted to a building must be controlled by one of the combinations: Photocell and motion sensor, photocell and time switch, astronomical time clock or EMCS with features of astronomical time clock, that does not allow the luminaire to be ON during the day, and may be programmed to automatically turn lighting OFF at night.
RECESSED LIGHTING
Recessed Downlight housings must be rated for direct contact with insulation (Type IC), as well as be labeled and certified airtight with air leakage less than 2.0 CFM at 75 Pascals when tested with accordance with ASTM E283. The opening must be sealed with a gasket or caulk between the housing and ceiling. The recessed housing shall not contain a screw based socket. In addition, the light source must be high efficacy and comply with Reference Joint Appendix JA8. It must also be marked “JA8-2016”.
SCREW-BASE LUMINAIRES
All luminaires that utilize a screw-based socket must contain lamps that comply with JA8 high efficacy requirements. All enclosed, screw-base luminaires, must utilize a compliant lamp rated for elevated temperatures.
HIGH EFFICACY LIGHTING
Per Table 150.0 A, fixtures with a GU-24 socket and compact fluorescent lamp or an inseparable LED source are not required to meet JA8.
CONTROL REQUIREMENTS BY SPACE
At least one luminaire in the bathroom, garage, laundry room and utility room must be controlled by a vacancy sensor. Preset scene controllers and EMCS can take the place of dimmers as long as the functionality meets code requirements.

Title 24 is enforced by the building or electrical inspector at the site of the lighting installation and may involve the homeowner, contractor and/or builder. The building permit process is used to identify and track compliance. If a lighting installation is noncompliant as installed, an occupancy permit maybe delayed or denied. Use this guide to select T-24 compliant products for your next project.
