L2D2 Lamps (Deuterium Lamps )
LONG LIFE : 4000 HOURS
4 times longer guaranteed life
I Life Characteristics
100
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.

L2D2 LAMPS
1×10-5AU
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 be obtained. This
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.

CHARACTERISTICS
Use of a ceramic structure with excellent thermal
stability ensures stable lamp operation even in
the presence of ambient temperature variations.

HIGH LIGHT OUTPUT : 1.3 TIMES HIGHER
1.1 times higher (L2-4000 series) (L2-2000 Series)
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.

SMALL INTENSITY VARIATIONS : 1/2
Compared to our conventional lamps
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.
