Another one that's not in maybe
as new condition, has seen about a year of service in an up-lighter in
this room, which is why it's a bit on the grubby side, and there's a
little blackening of the tube at the cathodes, nothing serious
though, and it seems to be holding up just fine - could maybe just have
done with a bit of a clean before I started snapping photos of it!
Warm-up time's a little slower than average maybe, about 90 seconds to
75% I'd guess, though without a photometer I can't really test that.
Once up to temperature though, colour balance is good, there's no
flicker, and the ballast is silent (As are 99% of them these days
anyhow), and the ballast doesn't get too hot.
Starting seems to be reliable, with a slight flicker occasionally
visible if the tube is at extremely low temperatures (< 0
degrees C), and obviously, taking a good deal longer to warm up from
that temperature.
Unfortunately, this lamp got broken when it had roughly 6'000 hours on
it. (My fault, trying to do three things at once, and I
dropped it). Was still working perfectly.
Shame
that, as I'd have liked to see how long it lasted! The ballast
however has since been scavenged and put into service in a 15W linear
fluorescent fixture in place of a magnetic ballast which could barely
keep even a brand new tube alight, seems to work just fine.
Note: These photos were taken on a very cheap circa 2003 digital camera hence are of poor quality and resolution. As I no longer have this lamp I'm afraid I won't be able to improve on these...Sorry.
