What is your point about a candelabra incandescent lamp? That concerns only lamps which use a "candelabra screw base as described in ANSI C81.61–2006, Specifications for Electric Bases, common designations E11 and E12." Moreover, that is from a section which specifically allows them to be incandescent, so long as they don't exceed a given power limit. You also seem to have missed the part where it says: > The rulemaking— (I) shall not be limited to incandescent lamp technologies; and (II) shall include consideration of a minimum efficacy standard of 45 lumens per watt. or the "Backstop requirement": > If the Secretary fails to complete a rulemaking in accordance with clauses (i) through (iv) or if the final rule does not produce savings that are greater than or equal to the savings from a minimum efficacy standard of 45 lumens per watt, effective beginning January 1, 2020, the Secretary shall prohibit the sale of any general service lamp that emits less than 300 percent of the average lumens per watt emitted by a 100-watt incandescent general service lamp that is commercially available on the date of enactment of this clause. This allows incandescent bulbs so long as they are significantly more efficient than those sold before 2007. As to why UK newspapers writers are supposed to understand the details of domestic US law, and why UK newspaper readers are supposed to care, in order to get an extra moment of irony - well, that seems like a lot of work for very little gain. Especially when the EU has very similar laws, so UK readers may default to think that the US is already in the same boat, so there's little to no irony available.
