the Japanese market, there is a far greater market for higher colour
temperature lamps such as this - in fact, Japan is one of the few
places in the world where there is still a strong demand for non-colour
corrected high pressure mercury vapour lamps on account of their high
colour temperature. They as a market, are also very picky about
the quality of the lighting - this tends to spill over to the lighting
devices themselves as well, the Iwasaki-EYE range for instance are so
beautifully well made that they are almost works of art.
domestic lamp from Panasonic doesn't attain quite such high marks in
terms of build quality, but is certainly a very well presented product,
the overall build quality seeming slightly above that usually seen in
domestic CFLs - that said - it ain't exactly cheap either! The
only site I could find which had this model listed was in Germany and
was selling these lamps for €15. While the Philips Genie range
these days can be readily picked up in supermarkets for less than £1.
Given the price difference there, you'd be expecting this to be a
bit of a premium product.
I have to confess to being a little
puzzled as to the intented application for this lamp - reflector type
CFLs are not all that unusual these days - but they tend to be fitted
with more conventional R shaped outer bulbs or plastic reflectors to
direct the light - rather than the slightly elongated globe fitted to
this lamp. The fact that this lamps reflector does not go
sufficiently far along the bulb to fully shield the U-bends of the
discharge tube result in a lamp which is vaguely directional - but with
a very, very wide viewing angle. The only application I could see
this lamp maybe serving particularly well would be in a recessed
fixture, though I think that a conventional R style lamp would do just
as good a job there if it was able to fit.
The light from this
lamp is a very neutral white, which utterly baffles the colour balance
on my camera. It's not quite the cold blue of 6400K lamps which
simular daylight, but it's far colder (i.e. higher colour temperature)
than 2600 or 3000K which are far more common - I think it's probably
about 5000K, which also ties in with the only information I've been
able to find on the model number as it's available today. For a
15W lamp, it's really quite bright I think too - though the reflector
style does make it a bit hard to judge.
My only gripe with this
lamp is that there's a bit of "hazy" residue on the inside of the glass
outer globe. Whether this is a residue that's been there since
manufacture, I don't know, it may also have occurred while the lamp was
in storage. If anyone else has one of these and can vouch for the
clarity or otherwise of the globe I'd be most interested to hear.
Panasonic lamps don't appear all that often over here, so I'm glad to have this one in my collection.
