Very typical example of a modern (2006) low cost compact fluorescent lamp, as available in Tesco stores throughout the UK as part of their "Value" range of products - though possibly this model has now been discontinued, when I was there today (9th June 2006), they had been replaced with plain "2-U" style lamps, also looking like a GE product however.  These lamps appear to be lower grade lamps made by GE for Tesco (and probably a bunch of other stores too, I've heard that Morrison's also use GE lamps, though I'm not so certain of that).  GE produce a visually identical lamp (even the packing is identical in shape) as part of their "Elegance" range, which can be seen here, but it has a rated lifetime of 8'000 hours, opposed to this version's 3'000 hour lifetime.  As with many of the lower cost CFLs, they're selling the energy saving more than the lifetime in this case.
