The L2-4000 series lamps
assure an operating life of
4000 hours-4 times longer
than conventional lamps.
This is the longest operat-
ing life of any deuterium
lamp.
By using a newly devel-
oped ceramic structure, a
uniform and optimum tem-
perature distribution, which
are the most important
factor for stable operation,
can
results in fluctuations of
only 0.05 %p-p in the light
output, as well as a re-
duced drift of only ±0.3 %/h.

The spacing between elec-
trodes is kept fixed by a
molded ceramic spacer.
This reduces the lamp to
lamp variations in the light
output to one half of that
obtained with our lamps
having a conventional all
metal structure.
The L2-2000 series lamps
produce 1.3 times higher
light output than conven-
tional lamps. The L2-4000
series lamps even offer
light output 1.1 times higher
than conventional lamps.

Since the ceramic structure has a small thermal
expansion coefficient, there is virtually no move-
ment of the arc emission point during operation.
