Hi Annie, I bought the stock list lightbulb item 5558 from BLT Direct. The mfr's (Pro Lite) part no is shown also.

My lamp holder is standard bayonet size. Not sure if they do other "caps" e.g. screw-ins whatever).
On the box it says
"Ultra compact design"
"Average life 10,000 hours"
"Up to 80% energy savings"
"Unsuitable for dimming circuits"
"Long Life"
Also:
1900 lumens
240V 6400K Daylight White
Also a pictogram which I take to mean can be switched on and off more than 20,000 times. I guess the significance is that incandescent ones were meant to wear out quicker by on/off switching.
The second review incidentally says that "it does what it says on the tin". Sure can't argue with that
Although only £8.38 onscreen, the bill was £14.80 incl VAT & £3.95 P&P so not cheap, though I'd willingly fight anyone who tried to take it off me now. I wish I'd bought two given I know I'm a happy bunny as it'd be brilliant (literally, lol) in any room for things like decorating whatever and it's easy enough to change it down if not needed
In case I get told off for advertising, I've only said what I've bought and there is enough info above for people to work out if alternative sources or brands are available.
I mentioned it to my sis who initially thought I was on about one of those SAD lights that cost £several hundreds - this seems a pretty good compromise to me
