Soft Glass Ultraviolet
Germicidal Lamps
Hot Cathode
Germicidal Ultraviolet Lamps
produce short wave radiation in
the range of 253.7nm
(nanometers) that have an
excellent germicidal effect.
Ultraviolet germicidal lamps are
similar to general fluorescent
lamps but are manufactured with
a special glass which
efficiently transmits
ultraviolet rays.
Hot Cathode lamps utilize
tungsten filaments, located
inside each end of the lamp,
which are coated with emission
material and, under normal
operation, govern the life of
the lamp. Frequent starting of
the lamp reduces the overall
lamp life. Lamp is also affected
by extreme hot or cold
temperatures. There are several
different lamps with varying
lengths and watts to choose
from. Most of these lamps use a
miniature bipin (G5) or medium
bipin (G13) base.
Lamps can be used in a variety
of air, water and surface
disinfection applications. Call
and speak with one of our
ultraviolet application
specialists to determine the
type of lamp best suited for
your application. |
