Hi Mike,
can't see a lumen claim in the ebay link you originally posted, I was going on the look of the LED modules. As an owner of plenty of LED torches over the years, the LED's that are on those bulbs look like "old fashioned LED's of the type that are for switchboard panels, ie to light up rather than project light. You see a lot of cheap LED torches with arays of these LED's and they look impressive but actually give out very little light. A later generation Cree LED looks very different and has a yellow patch that generates the light and a lens directly over it to focus the light.
