On January 1, new Title 20 regulations went into effect requiring certain LED lamps, small-diameter directional lamps, and general-service lamps comply with new performance, testing, and marking requirements. Certain lamps must achieve a minimum efficacy level of 45 lumens/W, higher than the current standard imposed by the Energy Independence and Security Act of 2007 (and meeting the backstop provision in the Act going into effect in 2020), and higher than halogen A-lamps currently produce. While certain specialty incandescent lamps will continue to be available for sale in the state, consumers will be limited to a choice of LED or CFL for general-service sockets once current inventories are sold.
Here’s a good fact sheet summarizing the Title 20 regulations. Here’s a good article summarizing the impact of the regulation and the battle behind the scenes.
