Ster-L-Ray™
Preheat Ultraviolet
Germicidal Lamps operated by a
preheat-start circuit that
employs a relatively compact and
economical ballast. The preheat
circuit requires four electrical
connections per lamp and a
slight to moderate delay is
needed to start the lamp. Due to
increased circuit complexity,
reliability is regarded as
slightly less than slimline or
cold cathode instant start
circuits.

1 Nominal length measured from
base face
to base face. 2 Wattage is lamp watts only and does not include ballast loss. 3 Ultraviolet output at 254 nanometers at 100 hours and 80ºF (approximate).
4 Microwatts per square centimeter at one meter from lamp.
5 Approximate ozone output in grams per hour under favorable conditions. Figures apply
only to ozone producing types. Please note that ozone output is subject to considerable
variation due to conditions under which the lamp is used; under many conditions, the ozone
output may be only a fraction of the specified figure.
** Also available in 4-pin configuration.

Ster-L-Ray™ Ozone-Producing
Lamps - Ozone (O3) is a
highly reactive form of
oxygen and is useful in
water purification, as a
deodorizer and as a
cleaning agent.
Ultraviolet wavelengths
shorter
than 200 nanometers are
capable of producing
ozone from oxygen (O2)
in the air. The mercury
vapor arc, in addition
to producing
considerable ultraviolet
output at 254 nm, also
produces a small amount
of output at 185 nm. The
high purity fused quartz
used in
Ster-L-Ray™
ozone producing lamps is
transparent to both
germicidal (254 nm) and
ozone producing (185 nm)
wavelengths.
Because it is necessary
to avoid exposing
personnel to high
concentrations of ozone,
the use of ozone lamps
is limited to
applications in which
ozone concentration will
not exceed .05 parts per
million in occupied
spaces.
Ster-L-Ray™
ozone producing lamps
are available in
slimline, cold cathode
and preheat types.
