We have had earlier dealings with Sonntek- got a lamp there for a
Perkin-Elmer 410 BIO whose pixel energy was not much better than the lamp
we had in there with over 2,000 hours on it.
We recently needed a new lamp for the "Linear instruments" detector
in our Michrom and bought one from the Second Source, as they are the
closest to us and we wanted to save a few bucks. The lamp came in
promptly, and lasted 2 days and then would not fire. We swapped lamps
with a Spectra Physics spectra Chrom 100 detector (= Linear instruments),
and the bulb worked OK in the spectra-Physics. Also, the Spectra-Physics
lamp with a lot of hours on it worked fine in the Michrom.
On discussion of this problem with Mike Medley of Michrom, he told
me they used to buy from Second Source but had the same problem- some
lamps would work in one detector and not in another, identical detector.
Caveat emptor!
