|Notes:||Here's one that must have sat on a shelf for a good number of years!
I very, very dimly remember seeing a couple of these in use in a hotel when I was very young, however certainly don't recall ever seeing one since.
Candle lamps with the twisted bulb shape (CF prefix) have always been a bit of a rarity in common use, though they've never actually been hard to find until the last couple of years when I've found myself suddenly limited to having to buy lamps at local supermarkets as all the smaller shops I used to frequent have disappeared. I've not however seen any examples recently with such a large envelope, this being a good 10mm or so wider than most candle lamps I've come across (normal diameter being 35mm). It appears that this is simply due to the decorative nature of this lamp, at least the current examples I've found using a bulb this size have all been decorative in nature - so this seems a logical conclusion.
Another reason I tend to think that they may have had cosmetic appearance high on the agenda is the orange external powder coating which has been applied to the tip of the lamp. This is a sufficiently thin coating and being quite some distance from the filament, does not have all that much effect on the actual light given off by the lamp aside from if you're looking directly at it from that end. The overall colour temperature of the light and the amount of light given off is pretty much exactly as you would expect from a 60W incandescent lamp, though maybe tending towards slightly warmer. It does look really rather interesting however if you look downwards at the lamp (or upwards if it's mounted cap-up in a ceiling fixture) with the lamp lit. Also, this one does look quite decorative even when not lit - which was probably part of the intention.
Another clue to its age I think is the styling of the packaging, I'm tending to think 1980s at the moment. If anyone can confirm that I'd be really glad to hear from you.
One interesting aspect of this lamp is that the pearl finish is created by an external coating rather than an internally etched bulb. While this has become more common in recent years (I've not been able to verify this, but more than one source I've heard from has indicated that this is mainly due to environmental concerns over the caustic chemicals involved in the etching process), it wasn't all that commonly seen in the past on normal domestic lamps.
BELL appear to be a company who have specialised in decorative lamps such as this for a long number of years - and still do in fact. What's even more interesting is that this very lamp still appears in their current catalogue (as of August 2010), despite this example appearing to be a good few years old judging from the packaging. Nice to see one of the smaller, British makers still going - I wish them all the best!
