LED 18 W HEAD:
➢ is an universal lamp used as the main lighting source during recreational diving, technical diving and underwater works
➢ construction:
• head body is made of surface anodized aluminium
• magnetic switch (without a pass through the housing) allows switching LEDs and adjusting power levels to 100%, 33% and 10%,
by rotating the ring at the back of the head body, each turning on and rapid rotation (incomplete turning off and on again)
adjusts the consecutive power level cyclically: 10% - 33% - 100% - 10% and so on, if a certain level of power is used for a few
seconds it is stored in memory and restored after restarting the unit
• sledge – element for mounting the goodman handle – unscrewing and using non-stainless screws is not advisable - may cause
damage to the head body
• connection lamp head to the battery by high quality flexible cable; protected against bending with plastic covers (at the plug
and head ends)
• optional connection by e/o cord – this option is available only when using a battery with a switch (necessary to cut off the
power supply before unplugging the cable); e/o cord cable polarization at the lamp head: "minus" in the output, "plus" on the
pin (other connection may cause damage)
• hermetic connector on the cable is protected against the admittance of water (eg. mechanical damage to the cable); the
polarization of the plug: "minus" on the body, "plus" on the center pin (other connection may cause damage)
➢ lamp head, as the source of light, has three Cree XML-2 diodes, with a color temperature of 5500 - 6000 K
➢ requires 14,4 V power supply, use of higher or lower voltage can damage the lamp head
➢ tested to a depth of 150 meters, 300 meters on request

➢ on the upper lid there is one output (capacity 6.8 Ah) or two outputs (capacity 10.2 Ah, Ah 13.6, 23.8 Ah and 41 Ah) to connect with
the lamp head; sealed to prevent the entry of water into the container when the plug is not properly inserted or when the output is
not properly sealed with a blind plug
➢ in “sidemount” version (available for capacities: 10.2 Ah, 13.6 Ah, 23.8 Ah and 41 Ah), the upper lid has two outputs, one (optionally
two) at an angle of 90°
➢ in the version with a switch there is a rotary ring for one output: turning positions: off / on
➢ has a belt mount on the tubular portion of the body (for capacities: 10.2 Ah, 13.6 Ah, 23.8 Ah and 41 Ah), for fastening with 50 mm
wide tape, the belt mount is screwed from the inside of the container (no disassembly possible); the “delrin” and “sidemount”
versions have no belt mount
➢ tested to a depth of 150 meters, 300 meters on request
BATTERY PACK:
➢ consists of Li-ION battery cells which feature small size and high capacity
➢ has a low self-discharge level (approx. 4% / month)
➢ has an electronic protection against: short circuit, overcharge and over-discharge (excessive discharge causes switching off of the
battery)
➢ does not require full discharge before recharging
➢ can be charged at any time and at any level of discharge
TERMS OF BATTERY USE:
➢ store in a dry and ventilated location within a temperature range of -20°C to +50°C, keep away from excessive heat and
humidity
➢ temperatures above +60°C may cause internal damage to the battery pack
➢ after storage below 0°C it is necessary to acclimatize the battery pack at the minimum +10°C for 4 - 5 hours before use
➢ charging a frozen battery may cause internal damage to the battery pack
➢ discharging (usage) of the battery may take place within a temperature range of 0°C to +60°C
➢ battery can be stored after charging to a level of 50 - 70% (longer storage of the discharged battery leads to its degradation)
➢ when storing the battery, charge it at least once every six months
➢ charge the battery only with the supplied charger, with current not more than 5 A and voltage not more than 16,8 V
➢ avoid discharging the battery beyond the automatic power cut-off level
➢ polarization of the battery: "plus" inside the output, "minus" on the housing
➢ it is strictly prohibited to:
• open the battery container
• alter the battery container and the battery assembly
• short-circuit the battery
• throw the battery
• place the battery into a fire or to store near an excessive heat source
• connect the terminals with something other than original GRALmarine connectors (optional e /o cord, while maintaining
the correct polarization)
• connect other than the original GRALmarine lamp heads
• charge the battery with a charger other than the one included in the set
• dive or immerse in water with open outputs (blind plug or attached plug of the lamp head)
• in versions with a switch: hitting, dismantling, disassembling the switch and storing the battery with the switch in position
“on” – much faster self – discharging process
BATTERY CHARGING:
➢ disconnect the lamp head cable from the battery
➢ plug the charger into an AC terminal of 110 - 230 V
➢ in a charger with LCD display it will turn blue and the text will appear; the correct charging voltage is 16,8 V
➢ in a charger without LCD display a red LED will appear
➢ insert the charger plug into the output on the battery container, if there is the LCD display it will show the percentage charge on
a red background and start the charging process
➢ when the battery is fully charged the LCD display will switch to blue, indicating 100% charge, in a charger without a display – red
LED will turn to green
➢ in case of strong discharge of the battery, the charger may blink (red / blue or red / green) when connected, remove the plug
from the battery and re-connect, it may be necessary to repeat it twice / three times
➢ charge the batteries with switch by the non – switched output or by the switched, with switch in “on” position
TERMS OF CHARGER USE:

OPERATING PRINCIPLES OF LED 18 W HEAD WITH BATTERY:
➢ Preparation:
• check the battery charge level before diving
• check for dirt or damage to the lamp head plug and the terminal(s) on the battery container
• insert the plug into the terminal (do not screw), push and adjust for the correct placement of the o-rings
• finger-tighten the nut
• make sure that the second output (if present in the battery model) is protected by a blind plug and adequately secured
• check whether the lamp head works by rotating the magnetic switch
• always have an alternative source of light (backup)
➢ Maintenance after diving:
• rinse the reflector and the battery container with fresh water (before disconnecting the lamp head from the container,
avoiding plug and output flooding)
• dry the set
• the head and the battery must absolutely be disconnected upon storage and transportation, to prevent accidental
switching “on”
• clean regularly
• wipe the front glass of the head with a soft, moist cloth; do not use alcohol-based detergents (these cause dulling and
cracking of the glass)
➢ IMPORTANT:
• periodically check the condition of the o-rings and threads, lubricate with silicone grease or silicone with Teflon
• never leave the head switched “on” or use above water: this can cause overheating, unsealing and damage to the
reflector
• to provide a sealed hermetic connection, the reflector plug must be inserted and screwed into the battery output
• immersion of the container with batteries with an open output or unscrewed head plug may cause flooding and damage
the battery
• do not open the battery container
• do not disassemble the lamp head
• care for mechanical damage: distortion of the head or battery container can cause flooding
• do not use any other source of power than the original GRALmarine batteries 14,4 V
• do not use any clamps or grips on the cable - this can damage the cable
• do not hang the lamp head on the cable - this can damage the cable or pull it out of the head
• mounting of carabiners, strings, etc. is possible only on the goodman handle or on the aluminium body of the lamp head
• do not disassemble the sledge used for fastening the goodman handle
