The US Environmental Protection Agency (EPA) has issued a guidance document intended to instruct certification bodies (CBs) in their implementation of verification testing of lamps, including LED-based products, that are certified to the Energy Star lamps V1.0 and V1.1 specifications. The guidance covers mandatory and randomly-selected tests and defines limited cases in which verification testing can differ from the original certification testing.
Intended to become effective September 1, 2014, the final draft of the Lamps V1.0 specification includes refinement of dimming requirements and other minor changes from draft 4 that was recently circulated for comments.
This year’s holiday electric bill will probably be a belated gift. This Department of Energy stat shows why: the estimated electricity cost to light a 6-foot tree with C-9 incandescent light strands will add $10.00 to an energy bill during a 40-day holiday season. But, by using C-9 LED strands, the cost is just 27 cents. I used three LED strands on my tree, but I also changed out an additional seven strands for other decorating needs. That should make a noticeable difference.
