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.
