Yeah, redundant assumption on my part. Mind you, the return email address can be made up any which way you like but in this case, it would have been reasonable to assume a UK location without further comment.
Oddly, they all look like figures typical for long life / rough service lamps rather than for the UK standard 1000 hour life GLS lamp. The only clue in that picture to suggest that they might be long life / rough service being the use of the word "Professional" on the packaging.
Anyway, harking back to the observation that modern "60W" 810lm LED GLS lamps seem to match or exceed expectations (for those of us in the UK at any rate), is simply down to the manufacturers being forced by regulation to use lumens output figures based on the more efficient American 120v incandescent lamp standard when such equivalency "Wattage Ratings" are included on the packaging by way of a guide to help their customers choose a replacement for an incandescent light bulb.
It's rather fortunate for us in the UK (and Europe for that matter) that the American incandescent lamp figures were the ones chosen to set the standard since this results in an LED GLS lamp that produces a little more light than our wattage equivalent incandescent lamps produce.
The increase is a very welcome one since choice of incandescent lamp wattage is typically based on a minimum acceptable level to keep their running cost as low as possible. The main reason we use 60W lamps in place of 150W lamps is on account of the profligate energy consumption such a "luxury item" as a 150W lamp would represent. A doubling or tripling of the light levels commonly used in homes lit by classic tungsten filament GLS lamps would be a very welcome improvement in all bar a few exceptional cases, hence my use of the phrase "You never had it so good." :-)
