No matter how common it is, I never know what "2.5x less than some reference number" means. Is it "divide the reference number by 2.5"?

- lucb1e 4y agoCorrect, i.e. 40W instead of 100W. It sounded more impressive than "40% of the original value" so I went with "2.5x less". Not the best measure to choose one's words by, admittedly.

- lucb1e 4y ago2x20 (notice plural 'bulbs' in the original message a few steps up the thread), and this is actually measured whereas iirc the box said a bit less And yes, in my opinion we erred on the high side, but it's not far off from what the original incandescent (which apparently was 2x50W, measured).
