CA Utility Proposal Would Raise Grow Lighting Efficiency Requirements For 2025 Title 24

The current California energy code (Title 24 Nonresidential) requires luminaires or lamps that are used for plant growth to have a photosynthetic photon efficacy (PPE) of at least 1.9 micromoles per joule (µmol/J) for indoor grow facilities with more than 40 kW of horticultural lighting load. Luminaires or lamps used for plant growth in greenhouses [...]
