California Energy Commission 2022 Building Energy Efficiency Standards (Title 24, Part 6) adds mandatory requirements for Controlled Environment Horticulture (CEH) spaces, and the requirements for horticultural lighting are as follows:

1. Indoor growing, horticultural lighting

In a building with CEH spaces and with more than 40 kW of aggregate horticultural light load, the electric lighting systems used for plant growth and plant maintenance shall meet all of the following requirement:

A. The horticultural lighting systems shall have a photosynthetic photon efficacy (PPE) rated in accordance with ANSI/ASABE S640 for wavelengths from 400 to 700 nanometers and meet one of the following requirements:

• Integrated, nonserviceable luminaires shall have a rated PPE of at least 1.9 μmol/J; or

• Luminaires with removable or serviceable lamps shall have lamps with a rated PPE of at least 1.9 μmol/J.

B. Time‐switch lighting controls shall be installed and comply with Section 110.9(b)1, Section 130.4(a)4 and applicable sections of NA7.6.2.

C. Multilevel lighting controls shall be installed and comply with Section 130.1(b).

2．Greenhouses, horticultural lighting

In a greenhouse with more than 40 kW of aggregate horticultural lighting load, the electric lighting  systems used for plant growth and plant maintenance shall meet the following requirement:

A. The horticultural lighting systems shall have a photosynthetic photon efficacy (PPE) rated in accordance with ANSI/ASABE S640 for wavelengths from 400 to 700 nanometers and meet one of the following requirements:

• Integrated, nonserviceable luminaires shall have a rated PPE of at least 1.7 μmol/J; or

• Luminaires with removable or serviceable lamps shall have lamps with a rated PPE of at least 1.7 μmol/J.

B. Time‐switch lighting controls shall be installed and comply with Section 110.9(b)1, Section 130.4(a)4 and applicable sections of NA7.6.2.

C. Multilevel lighting controls shall be installed and comply with Section 130.1(b).

We will continue to follow up on CEC Title24 and the global update of relevant regulations on horticultural lighting, and escort your lighting products to the international market!

BACL Service:

BACL is the Energy Star testing laboratory, certification body, and verification testing laboratory accredited by the EPA. At the same time we obtain the authorization and recognition of NVLAP (Lab Code: 200707-0), IAS (Accreditation No.: PCA-139, TL-1044, AA-797), CNAS (Registration No.: L2408, L5662, L6290, L9963, L11432, IB0343), A2LA(Certificate No.: 3297.01, 3297.02, 3297.03), and so on. Respectively have testing sites in US, Shenzhen, Dongguan and Kunshan, such places. With the ability to complete the energy efficiency aging detection of 60,000 lights at the same time. BACL is currently a large-scale energy efficiency testing laboratory in China.

We can provide you with testing and certification service, such as US Energy Star, DLC, DOE, CEC Title20, CEC Title24, LDL, FTC Label, European Union ErP, Canada NRCan, UK EST, Australia GEMS/VEET/IPART, Energy Efficiency Label ELI, Hong Kong Energy Efficiency Label and etc.
