CFL's again

I've just purchased a 20watt CFL from Tesco. On the box it is labelled 20watts, 1220 lumens, equivalent to 89watt conventional.On the lamp itself, the only understandable markings say 240volt, 140 mA.The 20watt Osram long life cfl that failed after a few months said 240volt 165 mAThe Tesco Value 15watt lamp that I put in while I found the replacement was labelled 240volt 144mA, which when multiplied up comes to over 33 watts.I understand that power factors may be involved, but this all seems a bit odd.Also, why are these things packed in the box so that when opened from the top one can't get them out without touching the glass?I have turned into Victor Meldrew.

I thought all those derive from Elihu Thomson (no p, by the way) - a Mancunian - so are in fact ultimately connected. Thomson-CSF (France) absorbed the Racal Empire (and Decca) and became Thales.
