TOP RUNNER is a Japan Ministry of Economy voluntary program that helps businesses and individuals save money and protect our climate through superior energy efficiency. This program is to identify and promote energy–efficient products and buildings in order to reduce energy consumption, improve energy security, and reduce pollution through voluntary labeling of or other forms of communication about products and buildings that meet the highest energy efficiency standards. To maintain consumer trust and improve the oversight of TOP RUNNER products, Japan Ministry of Economy has implemented third–party certification requirements and testing. TOP RUNER products must be third-party certified based on testing in JNLA-recognized laboratories.TOP RUNNER requires the effieciency of LED bulbs to reach 110 lm/W for cool white and 98.6 lm/W for warm white. We did it and 2 years earlier.
