Japan Amends Evaluation Criteria for Energy Consumption Performance of Lamps

The Japanese Ministry of Economy, Trade and Industry (METI) issued an amendment to the Notice on Evaluation Criteria for Energy Consumption Performance.

The conventional energy conservation standards for lighting equipment covered only fluorescent lighting equipment. LED lighting equipment is now added in the coverage of the new standards.

The conventional standards considered the energy consumption efficiency as the “brightness of the light source of lighting equipment (total luminous flux)”per electricity consumption. The new standards are based on the “brightness of lighting equipment (equipment luminous flux)”per electricity consumption.Note that the equipment luminous flux is smaller than the total luminous flux for the same fluorescent lighting equipment.

The conventional energy conservation standards for light bulbs only covered fluorescent lamps and LED lamps. Now incandescent bulbs are added to the new standards.
