CHARGING/RECHARGING THE SPOTLIGHT

This unit is shipped in a partially charged state. Charge unit after purchase and BEFORE first use using either the 120 volt AC 

charger or the optional 12 volt DC charger for approximately 3-5 hours. Charge after each use until the battery/charge status 

LED indicator lights green.

IMPORTANT: When the unit is not in use, we recommend that the battery is charged at least every 30 days.

CAUTION: TO REDUCE THE RISK OF PROPERTY DAMAGE:

• Make sure the unit is thoroughly dry before charging or recharging. If the unit has been submerged, wipe it dry with a soft 

cloth before opening the end cap.  If water leaks into the charging port, the unit can sustain permanent damage.

• Never place the light face down on any surface when charging.

• Failure to keep the battery charged will cause permanent damage and result in poor performance.

Charging/recharging using the 120 volt AC charger

• Make sure the spotlight is turned off.

• Unscrew (counterclockwise) the waterproof end cap on the back of the unit and remove it.

• Insert the barrel connector of the AC charger into the 12 volt DC charging port on the back of the unit. Insert the plug end 

into a (powered) standard North American 120 volt 60Hz outlet.

• Charge until the battery/charge status LED indicator lights green (approximately 3-5 hours).

• Replace the end cap on the unit, screwing clockwise until the triangular arrow on the end cap is pointing to the dot icon on 

the rear of unit. Make sure it fits securely, but do NOT overtighten.

Charging/recharging using the 12 volt DC charger (optional accessory)

CAUTION: NEVER connect the 12 volt DC charger to a positive grounded vehicle.

• Make sure the spotlight is turned off.

• Unscrew (counterclockwise) the waterproof end cap on the back of the unit and remove it.

• Plug the barrel tip of the supplied 12 volt DC charger into the 12 volt DC charging port.

• Insert the 12 volt DC plug end into the accessory outlet of your vehicle or other 12 volt DC power source.

• Charge until the green battery status LED lights (approximately 3-5 hours). DO NOT CHARGE FOR LONGER THAN 5 HOURS 

USING THIS METHOD.

• Replace the end cap on the unit, screwing clockwise until the triangular arrow on the end cap is pointing to the dot icon on 

the rear of unit. Make sure it fits securely, but do NOT overtighten.

Note: 

When using a vehicle’s 12 volt DC accessory outlet as a charging source, be aware that some vehicles require you to turn on the ignition to power the

accessory outlet. 

IMPORTANT NOTES:

• If either of the chargers is plugged into the spotlight while it is operating, the unit will not charge. The unit will begin 

charging once the spotlight is turned off.

• If either of the chargers is plugged into the spotlight while the built-in low voltage protection is activated, the unit will 

automatically turn off and begin charging.

• If the on/off trigger is pressed when charging, the spotlight may not operate until the charger is disconnected and the 

spotlight is turned off, then on again.

• Once the unit begins charging, the spotlight will not operate until the charger is disconnected.

• When the battery/charge status LED indicator lights green, a “beep” will sound to indicate the charging process is completed.

OPERATING INSTRUCTIONS

Important note: 

When either charger is plugged into the 12 volt DC port, the unit is in charging mode. The spotlight will not 

run with either of the chargers plugged in.

CAUTION: TO REDUCE THE RISK OF PROPERTY DAMAGE:

• Never operate this spotlight unless the rubber “O” ring, rubber bezel and lens are intact and  properly seated; and the 

waterproof end cap is securely in place.

• Never operate the spotlight in areas with high strength magnetic fields, such as in the vicinity of AC power generator, etc.

• Never operate this spotlight at depths greater than 6 feet.

• Never operate this spotlight in water temperatures other than between 41ºF and104ºF (5ºC and 40ºC).

• This spotlight is designed to operate for up to one hour under water.

Operating the spotlight

The On/Off Trigger turns the unit on and off, and is also used to choose either the high or low brightness setting.

• Press the On/Off trigger once to use the spotlight in its high (brightest) setting.

• Press the On/Off trigger again 

within 5 seconds

 to use the spotlight in its low (dimmest) setting.

• Press the On/Off trigger a third time to turn the unit off.

or

• Press the On/Off trigger once to use the spotlight in its high (brightest) setting.

• Press the On/Off trigger again 

after 5 seconds

 to turn the unit off.

• Do not drop or throw spotlight. It contains a nickel metal hydride rechargeable battery pack.

• Use only with AC or DC charging adapters that are provided with unit. Plug in the charging adapter at the spotlight first, then 

plug into the charging source.

• Do not overcharge: Recharge up to 5 hours maximum.

• After charging/recharging, disconnect charging adapter or extension cord and wait 5 minutes before use.

• Do not crush, cut, pull or expose charging adapter cords to extreme heat.

• Position charging adapter cords so they do not become entangled or become a safety hazard. Keep charging adapter cords

away from sharp edges.

• Do not open body casing. There are no user-serviceable parts inside.

• Do not operate the spotlight without the lens in place.

• To reduce risk of damage to electric plug and cord, pull by plug rather than cord when disconnecting.

• Do not attempt to charge the unit if the charger is damaged – return the charger to manufacturer for repair or replacement.

INSTRUCTIONS PERTAINING TO WATERPROOF SPOTLIGHTS

The rubber “O” ring acts to preserve the waterproof qualities of the spotlight. The “O” ring seals the end cap to prevent water 

from entering the gap. An undamaged rubber “O” ring, rubber bezel and lens, and proper sealing of the end cap before use 

are very important.

CAUTION: TO REDUCE THE RISK OF PROPERTY DAMAGE:

• Attempting to remove the rubber “O” ring; use of the unit with a damaged “O” ring, rubber bezel or lens; improper sealing 

of the waterproof end cap; and/or submerging this unit in depths greater than 6 feet may cause the unit to no longer be 

waterproof. Do not submerge the unit if these conditions exist or the unit could sustain permanent damage.

• Submerging this unit in depths greater than 6 feet and/or operating it in water temperature other than between 41ºF and 

104ºF (5ºC and 40ºC) could result in leakage, warping or malfunction, causing permanent damage to the spotlight.
