Introduction
UV Hand Lamps offer a uniform and intense source of ultraviolet light (radiation). The lamps
use 6-watt tubes and emit 254nm, 365nm or white light for exposure/illumination of materials.
All UV Hand Lamps can be used with the universal J-138 Lamp Stand.
NOTE: Though the manual refers to the midrange UV waveband as 302nm, others refer to
this region as 300nm or 312nm. The spectral output of all these regions is the same.
CAUTION: Shortwave and midrange UV radiation will cause damage to unprotected eyes
and skin. Before operating any unit, be sure all personnel in the area are properly protected.
UV Blocking Eyewear should be worn as well. Additional UV protective wear can be ordered
including spectacles, goggles and faceshield.

Operation
Safety Precautions
Shortwave and midrange UV radiation will cause damage to unprotected eyes and skin.
Before operating any unit, be sure all personnel in the area are properly protected. UV
Blocking Eyewear should be worn as well.
Using the Lamp
Plug power cord into a properly grounded electrical outlet. The proper voltage of the lamp
is found on the product information label.
The power switch is conveniently located on top of the unit to turn the lamp on or off.
For models with multiple wavelengths the switch allows selection of wavelength or to shut
the unit off.
Each lamp comes with two UV tubes. Models with two tubes of the same wavelength
operate with both tubes on at the same time. Other models operate with only a single
tube a time.

Service Procedures
Cleaning and Care
Clean unit surface with a damp soft cloth or sponge. Never use abrasive cleaners (can damage the UV
filter surface).
Replacing Tubes
Disconnect the lamp from the electrical supply before replacing tubes.
Remove the two Phillips Head screws located in the end cap.
Grasp the extruded housing and slide the chassis and filter out together away from the switch.
Disconnect the interior Molex Connector (Fig. 1) and slide the chassis and filter out from the
housing completely.
Once out of the extrusion, the chassis and filter will come apart.
Carefully grasp the tube ends and twist one quarter turn until it works free (Fig. 2)

Insert the new tube, giving it a twist to lock in place.
Reassemble the lamp. Do not pinch wires during assembly.
