With the purchase of this NOCTURN UltraViolet Light Source, you are assured of the most
flexible and best performing ultraviolet fixture in its class.
The ultraviolet light source is a high-intensity lighting system for indoor and outdoor use.
The fixture is used to evenly illuminate fluorescent materials in many environments, espe-
cially when an extremely wide field or projection across great distances is necessary. The
400 watt fixture can be manually operated or addressed for use with standard DMX-512
protocol lighting control. The lighting fixture has been designed for quiet and efficient
operation, maximum lamp life and easy field serviceability.
IMPORTANT
Before attempting to operate this light source, read the entire operation
manual. Improper set-up, use or servicing may cause damage to the
fixture and/or lamp that can void any applicable warranty!

I. INTRODUCTION
The NOCTURN UltraViolet Light Source is intended to provide a source of illumination for
fluorescent materials. The fixture can be used in a variety of applications where high inten-
sity fluorescent illumination is desirable, such as entertainment, special effects, industrial,
and scientific uses.
Caution/ Warning Statements
The following cautions and warnings apply to the use, maintenance and care of the UV
light source.
•This operation manual should be read and fully understood to enhance operator safety.
•Disconnect the power cord prior to attempting any servicing to the fixture. Always verify
the cord is unplugged prior to opening the front cover for lamp replacement or servicing
the fixture.
••
••
•DO NOT OPERATE THE FIXTURE WITHOUT AN INTACT FILTER WINDOW
SECURELY IN PLACE. REPLACE THE WINDOW IF ANY CRACKS ARE FOUND
THAT MAY ALLOW UNFILTERED LIGHT TO ESCAPE.
••
••
•THE LAMP PRODUCES INTENSE LEVELS OF ULTRAVIOLET RADIATION WHICH
WILL CAUSE BURNS OR DAMAGE TO BARE SKIN AND UNPROTECTED EYES.
DO NOT ALLOW THE FIXTURE TO OPERATE IN ANY MANNER THAT ALLOWS
UNFILTERED LIGHT TO BE RELEASED.
•Adequate cooling is necessary for operation of the fixture. Provide a minimum of 6” free
air space on the sides and rear of the fixture. Do not place any combustible objects
closer than 24” in front of the fixture while it is operating. The fixture must not be oper-
ated in confined areas subject to ambient temperatures higher than specified (see
Section I, System Specifications).
•Allow a minimum of 10 minutes for lamp cooling before attempting to replace the lamp.
Portions of the lamp attain extremely high temperatures during operation and can
cause serious burns if touched while hot.
•Do not subject the fixture to extreme mechanical shock or rough handling that may
damage the lamp or internal fixture components.
•For maximum lamp life, allow the lamp to remain ON for a minimum of 5 minutes any
time the lamp is ignited.
•Clean the lamp with isopropyl alcohol and a lint-free cloth after it has been installed into
the fixture to help eliminate premature failure from contaminants. This procedure will
help increase life and performance.
•When removing a fixture for servicing or inspection, exercise extreme caution when
loosening the clamp from the pipe or truss. The fixture may be installed in such a man-
ner that a moment arm is created during the installation. This may cause the fixture to
swing down violently when the clamp is loosened.

System Description
The fixture uses a special double-ended linear high intensity discharge lamp that has been
custom manufactured to NOCTURN specifications. The lamps will produce maximum
levels of ultraviolet energy peaked at 365 nanometers (UV-A).
In combination with the Atek  reflector, the fixture is able to provide greater output in the
UV-A region than other similar fixtures in the respective classes.
When the fixture is energized, the lamp will immediately ignite and output will steadily
increase for several minutes. After this brief period, the lamp will stabilize and reach a
maximum output.
By utilizing a special borosilicate filter window, dangerous ultraviolet radiation (UV-B and
UV-C) have been eliminated and minimum visual and infra-red energy is transmitted.
To enable flexibility, mounting points are provided which allow accessories to be used with
the fixture to externally control the light output (douser, barn doors, etc.).
Basic control interfacing is performed on the rear of the fixture. An illuminated display
shows either the fixture address or lamp life hour meter mode (user selectable) for simplic-
ity of fixture control.
The 400 watt fixture incorporates standard 5-pin XLR ports for the use of daisy-chaining in
a DMX control environment.
To enable quick and easy installation, the fixture is provided with a truss clamp attached to
the yoke. The clamp will accommodate 1-1/2” to 2” diameter pipes. Alternately, the yoke
incorporates a 1/2” hole to accommodate either a Baby or Standard pin for use on a stand.
NOCTURN recommends that the supplied safety cable be attached during installation to
prevent the fixture from dropping .
