The iconic incandescent light bulb is not dead yet but could well fade away slowly

It has been 12 years since the passage of the EISA and we have seen tremendous gains in overall residential lighting efficiency. However, additional steps contemplated by the law are still in play and remain controversial. In September, a new rule that eliminates previously adopted changes to the definition of General Service Lamps (GSLs) and General Service Incandescent Lamps (GSILs) became law. This action maintains the exemption for certain bulbs from the revised efficiency requirements. In addition, the DOE determined that its actions in this rulemaking do not trigger a backstop provision in the law that would have required all GSIL bulbs to meet a 45-lm/w efficiency requirement by January 1, 2020.
