CEC approves proposed amendments to BCS efficiency requirements
The California Energy Commission has finalised its efficiency specifications for Battery Charging Systems. Key items include:
- Efficiency requirements for a typical mobile device BCS are twofold: 24hr charge and maintenance energy must not exceed (12 + 1.6Eb) Wh, and the sum of maintenance mode and no-battery mode power must not exceed (1 + 0.0021Eb) W, where Eb = Battery capacity in Wh;
- adoption of the DoE test method, approved in June 2011, for BCS with rated input power ≤ 2 kW; and
- confirmation that consumer products must comply by Feb 2013, whereas larger capacity ≥ 20 Wh systems have until Jan 2014 for compliance.

Energy Star publishes new lamps specification version 1.0
Energy Star has now published version 1.0 of a new standard to replace both ‘CFLs’ and ‘Integral LED Lamps’. Key points for LED drivers include:
- power factor > 0.7 for PIN > 5 W; lamps with PIN ≤ 5 W are PF-exempt;
- efficacy ≥ 55 lm/W for PIN < 10 W and efficacy ≥ 60 lm/W for PIN ≥ 10 W;
- lamp lifetime ≥ 10,000 hrs and warranty ≥ 2 years, based on usage of ≥ 3 hours per day.
A definition, method of measurement and compatibility metric for dimmable lamps are also all in development.

Energy Star proposes new Lamps specification
Energy Star is proposing a new standard to replace those for CFLs (V4.2) and Integral LED Lamps (V1.3). The new standard is likely to consider possible changes to the following current requirements:
- power factor >0.7 for PIN >5 W;
- efficacy >50 lm/W for PIN <10 W or >55 lm/W for PIN ≥10 W;
- and warranty ≥3 years (note that the warranty is already ≥ 5 years for Luminaires).
