California Revises LED Quality Spec Requirements

Mon, 01/23/2017 - 15:55 -- MrGreen

LED lamp manufacturers now have to meet new efficacy and performance requirements to qualify for California based rebates.

In December, the California Energy Commission (CEC) approved version 3 of its LED lamp quality specifications. Started in 2012, the Voluntary California Quality LED Lamp Specification program sets minimum requirements that lamps must meet in order to be eligible for state-funded investor owned utility (IOU) rebate programs. The revised requirements became effective January 1, 2017.

While earlier versions aligned primarily with ENERGY STAR® lamp program specifications, version 3 aligns with California’s recently approved Title 20 mandatory LED efficiency requirements. The first tier of the mandatory requirements doesn’t become effective until January 2018. The CEC adopted the version 3.0 voluntary specification to continue driving the market towards higher quality products, before the mandatory requirement effective date.

In order to be eligible, a lamp must meet the following criteria:

  • Have an ANSI standard E12,E17, E26, or GU24 base
  • Have a brightness output of ≤ 2,600 lumens, with a minimum output ≥ 150 lumens for candelabra bases and ≥ 200 lumens for all other bases
  • Emit a white light with a correlated color temperature (CCT) between 2,200 K and 7,000 K
  • Have a Duv1 ± 0.012

Key elements of the new voluntary requirements include:

  • Minimum luminous efficacy: 68 lumens/watt before 1/1/18, 80 lumens/watt from 1/1/18
  • Minimum combined efficacy score: the sum of the lamp’s luminous efficacy and 2.3 times its CRI must be ≥ 282 before 1/1/18 and ≥ 297 from 1/1/18
  • Color rendering index (CRI) ≥ 82. Individual color scores of R1, R2, R3, R4, R5, R6, R7, and R8 ≥ 72
  • Power factor ≥ 0.7
  • Maximum standby mode power consumption of ≤ 0.2 W for connected lamps (starting 1/1/2018)
  • If dimmable, minimum dimming level of 10%
  • Reduced flicker operation: lamp must have percent amplitude modulation (percent flicker) < 30% at frequencies < 200Hz
  • Rated life of ≥ 10,000 hours (determined by lumen maintenance and failure test procedure)
  • Light distribution per the current ENERGY STAR lamp program specification
