The Apeks Luna-X is a lightweight and robust umbilical canister dive light that is perfect for exploration technical diving. The light has three beam widths and three brightness settings to precisely tailor the illumination mode your dive requires from 3 hours & 3300 lumens in full-high mode to 14 hours & 750 lumens in spot-low mode. While Apeks has not published an official IPX8 test rating for the Luna-X, the "unofficial" depth rating is {330 fsw | 100 msw}.

Easy Operation: The two control buttons of the Luna-X are at back of the light head for ease of use. To turn on the light, quickly double-press either button. The light will come on with the mode in which it was last operated. Briefly pressing the left button will select the intensity while the right button will select the beam width. Switch off by pressing and holding either button for a full second. The light also has a strobe mode that can be activated when the light is off by making a long press and hold of either button for three seconds.

Battery Charge Remaining Gauge: When the Luna-X is switched on or the mode is changed, the OLED text display shows the remaining runtime in hours and minutes for 10 seconds. A color LED will also continuously indicate at a glance the percentage of the battery charge remaining: Green 100-80%, Green-Pulse 85-70%, Amber 70-55%, Amber-Pulse 55-40%, Red 40-25%, Red-Pulse 25-10% and Red-Flash less than 10%.

Illumination Modes: The Luna-X features variable light beam and lumen output controls that can illuminate wide areas to reduce backscatter or produce a tight intense light for signaling. The combination of three beam widths and three brightness levels means there are nine possible illumination modes that provide beam widths from 8° to 80° and light output from 750 to 3300 lumens yielding 3 to 14 hours of burn time.

Full 3 hrs /3300 lumens 6 hrs /1800 lumens 14 hrs /850 lumens
Wide 5 hrs /2000 lumens 8 hrs /1350 lumens 12 hrs /1000 lumens
Spot 6 hrs /1350 lumens 10 hrs /1000 lumens 14 hrs /750 lumens

Transport Safety: A safety feature of the Luna-X is the travel lock. To disable the controls against inadvertently turning on the light, while the light is off press and hold both buttons for a full second. Another long press and hold of both buttons will reenable the controls. The travel lock is also automatically disabled if the battery is disconnected and then reconnected to the light head. The {1.18 lb | 535g} Lithium-Ion 27.2Ah 3.6V battery is rated at 97.9 watt-hours (the rating is clearly etched on the canister) ; that is under the maximum allowed by TSA for air transport and also meets the requirement to be able to detach the light head.

Charging: To charge the battery, disconnect the light head umbilical from the canister port, ensure the port is completely clean and dry, then connect the charging cable to the canister port and plug the charger into mains power. While the battery is charging the LED on the charging cable connector will illuminate RED and when the battery is fully charged the LED will change to GREEN. A completely depleted battery can take up to 9 hours to receive a full charge. Best practice is never leave charging unattended then once the LED turns green, unplug the charger and disconnect the charging cable from the battery.

What's in the Box: The Apeks Luna-X light head and { 46.5 in | 118 cm} umbilical cord, aluminum Goodman style handmount with easy grip rubber handle, a 97.9 Wh battery with thermally insulated aluminum canister, plate for attaching the battery can to {2 in | 5 cm} webbing, universal mains battery charger, printed quick start guide, and travel case.

Apeks Luna Series Lights Feature Intelligent Thermal Management (ITM) for Longer Burn Times

All LEDs have a temperature range where the balance between power consumption and lumen output is at peak efficiency, beyond this temperature the LEDs become inefficient. The thermal management system monitors the temperature of the LEDs and adjusts the electronics accordingly so that the LEDs remain at their optimum efficiency. This automatic adjustment of the power consumption doesn't noticeably decrease light output, but it does significantly improve burn time. The combination of the Intelligent Thermal Management electronics, together with increased heat dissipation of the advanced Luna body design, ensures no power is wasted thus maximizing burn time while minimizing battery size.

Apeks Luna series dive lights have a TWO YEAR Limited Warranty against defects in material and workmanship.

Care and Feeding of Lithium Chemistry Rechargeable Batteries

Dive light batteries have changed over the years as a result of advances in technology: originally lead-acid, then Ni-Cad, next NiMH, and now Li-ion chemistry has replaced previous technology in most rechargeable canister and handheld lights. Lithium-ion is a rechargeable battery technology that offers the advantage of longer burn times and almost zero self discharge, but even with recent advances there are safety concerns with Li-ion chemistry batteries that affect their transport. However, if the individual lithium-ion battery packs in your canister light are rated less than 100 watt-hours, and in some cases less than 160 watt-hours, they are approved for transport in the US on passenger aircraft.

​Most handheld dive lights and canister lights now use lithium-ion rechargeable batteries, which have some specific recommendations for their care that differ from other types of rechargeable batteries. The important thing to remember is that the useful service of the life of the battery is more about the number of times it has been discharged and recharged (called a cycle) than the total amount of burn time. A typical lithium-ion consumer grade battery will last between 300 and 500 cycles, but improper handling can drastically reduce the number of charge cycles it will support or the amount of charge it can hold.

Many divers don't realize the nature of lithium-ion rechargeable battery chemistry is such that the batteries will have a much longer service life when they are stored with less than 50% charge. For maximum service life, lithium-ion chemistry rechargeable batteries should be stored with a partial charge, and if storing for an extended period then sealed in a moisture proof container at about {40°F | 5°C} (i.e. your refrigerator, but NOT the freezer). Especially don't keep batteries stored on the charger, besides being a safety issue this can have the effect of both keeping them fully charged and also frequently mini-cycling the battery which will cause them to wear out extremely fast.

If your light has removable batteries, take extra care to properly orient the battery polarity with the charger or dive light; the positive end of individual cylindrical lithium-ion batteries can be difficult to distinguish from the negative end because both ends look flat. Always orient batteries in the device by looking at the actual plus (+) and minus (-) polarity markings on the side of the body of the battery. Attempting to charge the battery with reversed polarity is likely to drastically shorten the life of the battery or may cause damage such that the battery will no longer hold a significant charge. Even worse is installing a battery with the polarity reversed in a light that holds several batteries in series and then turning on the light; the battery will be damaged due to overheating or may catch fire and explode. If there is more than one battery and especially if there is a carrier, double check to make sure all batteries are oriented correctly - many carrier designs have one battery that is oriented opposite from all the others.

​During use, the electronic circuit in protected rechargeable batteries will normally prevent their over-discharging to the point of damage. However, if you want to maximize the service life of the battery then try to avoid burning the dive light until it goes completely out and do NOT recharge the battery immediately after diving. The best time to fully charge the battery is shortly before your next dive trip. Finally, keep in mind that heat is the enemy of battery life, so take care not to leave your dive light exposed to the hot sun. Allowing the batteries to get very hot from sun exposure during travel to and from the dive site or the surface interval between dives can drastically shorten the life of the battery.
