The 2024 “State of the Cannabis Lighting Market” report reveals a significant shift in lighting technology among cannabis cultivators, particularly the increasing adoption of light-emitting diodes (LEDs). Over 70% of participants now use LEDs throughout all growth stages, a dramatic increase from 2016. In the vegetative phase, 78% utilize LEDs, while 77% report using them for flowering, with declines in the use of traditional lighting like high-pressure sodium (HPS) and fluorescent lights. The report highlights a growing focus on energy efficiency and crop quality as key decision factors driving cultivators toward LED options. Challenges remain, with energy cost management as a primary concern; however, utility rebate programs are aiding many growers in transitioning to LED systems. The data also indicates a rise in median canopy sizes and average yields, underscoring the relationship between advanced lighting technology and improved cultivation outcomes.
