The UMX16URL is the 16 inch ez Plug-in replacement
UV-C lamp for the Ultravation UltraMAX
GOLD Whole House UV Air Treatment System,
models:
UMX1036 and UMX2036.

The
UltraMAX GOLD Integrated lamp models UMX1036
and UMX2036 use Philips compact-twin "U"
shaped lamps that effectively double the length
and intensity of the lamp. All UltraMAX UV lamps
use Philips Sterilamp technology. Patented Sterilamp
technology means highest output over the life
of the lamp. Ultravation's safe and easy-plug-in
UV lamp systems make changing lamps a breeze.

The manufacturer recommends you change the UV
lamps every 2 years under normal operating conditions.
Note:
If you have the UMX2036
system you may need to purchase the two lamp pack
to change all your UV lamps.
