can you recall the lumens figure on those 60W lamps
(assuming that you're in the UK)?

The clue's in the email address :-P

I'd expect a much lower figure than the 806/810 lumens figure typical of a "60W" LED lamp for 240v 1000 hour rated GLS lamps.

They were not [marked as] rough service lamps just normal "old hat light
bulbs" this is the type they'd bought, so 500 lm.

Different wattages from other photos from the same eBay seller

40W pearl = 270 lm
40W clear = 280 lm
60W pearl = 500 lm
60W clear = 520 lm
100W pearl = 970 lm
100W clear = 1000 lm
150W pearl = 2000 lm
150W clear = 2100 lm
