locking ring to the right over the plug to secure.
2. Press ON the BLACK ballast rocker switch.
3. Press ON the RED Inverter rocker switch.
FOR DC OPERATION
®
1. Connect the 12-volt plug to the Spectroline
BP-12A 12-volt battery pack or to a suitable DC
supply. The BP-12A must be fully charged before using! Refer to the BP-12A operating
instructions for full information.
2. Insert the plug into the receptacle on the battery pack.
3. Align the top notch of the 7-pin plug on the DC cord to the notch in the ballast outlet; turn the
locking ring to the right over the plug to secure.
4. Press ON the BLACK ballast rocker switch.
5. Press ON the RED Inverter rocker switch.
NOTE: The BP-12A battery pack includes a 12-volt battery, 120V/60Hz-charger, the BP-12A/F
has a 230V/50Hz charger, the BP-12A/FA has a 240V/50Hz charger and the BP-12A/J has a

OPERATOR SERVICING
The following instructions are intended for limited servicing of the lamp. Do not perform
any servicing that is not covered in these instructions. Return the lamp to the factory for
maintenance not covered in this section.
HOUSING AND FILTER MAINTENANCE
CAUTION: Always shut off the switch on the ballast and unplug the ballast from the power
outlet before performing any maintenance or servicing. Allow the lamp to cool before
handling.
Clean the lamp and ballast housings with water and a mild detergent and wipe dry. Periodically
clean the filter with a glass cleaner and a soft cloth.
FILTER REPLACEMENT
The lamp is shipped with a 2F958 filter lens. This may be used with either the
BLE-35RA spot bulb or the BLE-35RAF flood bulb. The 2F350 filter lens may be ordered with
a BLE-35RA spot bulb (only) to produce a more diffused spot beam
that is not as wide as the flood beam.
1. Peel the silicone-rubber filter holder from around the circumference of the lamp housing. The
filter will remain inside the filter holder.
2. Press the existing filter out of the filter holder.
3. Press the new filter gently but firmly into the filter holder.
4. Reattach the filter holder by pressing it around the circumference of the lamp housing with the
heel of your hand. Be sure the groove in the filter holder seats over the rim of the housing.
