CAUTION
(Risk Group 2): Possibly hazardous optical radiation emitted from this product. Do not stare at operating lamp. May be harmful to the eye.

WARNINGS

Prior to installing your OceanLED Light, carefully review and adhere to all included safety warnings and instructions to prevent potential property damage, serious injury, or fatality. Furthermore, ensure compliance with local regulations regarding the use of coloured lighting in your area.
Do not operate lights out of water for a period longer than 5 minutes followed by an OFF period of at least 1 hour. Exceeding this may cause damage to the light unit.

Ensure the bonding point of the light is fitted to the cathodic protection system on the vessel. Check conductivity between earth bonding point and aluminium bronze front bezel. If mounting the light to metal, carbon fibre or wooden hull, ensure that suitable measures have been put in place to account for the effects of galvanic corrosion or wood deterioration, i.e., use of Delrin sleeve components (Isolation Kit).
Salt is highly corrosive, especially to metal and certain surfaces. While OceanLED lights use saltwater-resistant materials, installation screws and fasteners must be marine-grade stainless steel or equivalent and should be inspected annually to ensure long-term performance.

Never connect/disconnect lights with power applied as irreversible damage may occur. Ensure polarity of power connections is correct. Failure to do this may invalidate the warranty.
Explore E2 light is for mounting directly to a flat surface. Ensure front of lights are always fully submerged and not fitted on planning / running surfaces that may impact on water since this may damage the product. Also ensure the rear of the light is in a dry area and not subject to a wet environment. Failure to do this may invalidate the warranty.

Do not submerse your cable ends in water; cable and connections exposed to underwater submersion will not be covered by warranty.
Never Use Solvents! Cleaners, fuel, and other products that may contain strong solvents, such as acetone, that attack many plastics greatly reducing their strength and irreversibly damaging the special lens coatings and cable sheathings.

Never clean lights using a high-pressure jet wash – this will invalidate warranty.
Do not coat the light’s glass/lens with any product, including but not limited to clear antifouling paints or similar, without consulting OceanLED for advice. Failure to do so will void your warranty.

If bottom painting ensure the coating is applied as instructed in the “Finalizing The Installation” section. Failure to do so will invalidate your warranty.

Installation Checklist

Decide on light spacing – OceanLED recommendations available. Rear of lights must never be exposed to wet environments inside the hull.

Ensure correct cable gauge is used (refer to relevant cable gauge chart).
Preparing the hull (Isolation kit required for conductive hull materials or wooden hulls). Ensure hull thickness is below the maximum 60mm (2.36”)

Make sure the lights have been fitted following the correct orientation.
Correct marine sealant applied evenly around bezel. Ensure fully watertight seal is created after sealant cures.

Correct clamping of light fixture onto hull. Never leave vessel unchecked for a few days after install. Always check routinely for a few days after installation to ensure the install is correct and fully sealed.
Light(s) correctly bonded and vessel bonding system check carried out (refer to relevant schematic and test procedures).

Test installation BEFORE entering water. Never connect/ disconnect lights whilst powered ON. Never leave lights ON out of water for longer than 5 minutes followed by an off period of 1 hour.
Troubleshooting if required – most issues can be resolved by following the guidelines.

Overview

Identifying your model

Product components breakdown

Power Source
Most installations will utilize on-board 12/24V DC power supply from a marine battery. However, if AC to DC power supply is being used, please allow at least 15% reserve for voltage fluctuations due to variables beyond your control such as ambient temperature and supply voltage fluctuations. This is to ensure your lights are always receiving the proper voltage and to ensure the power supply is not “overloaded”, causing premature failure. Use chart below in determining power supplies.

Power Consumption and Recommended Fuse values

Model	Current @ 12V DC	Current @ 24V DC	Max Nominal Power consumption	15% reserve in Watts	Recommended fuse 12V/24V DC
E2 Ultra White	3.5A	1.5A	42W	50W	4A
E2 Midnight Blue	3.5A	1.5A	42W	50W	4A

Preparing the Hull

When installing an Explore unit, please ensure there is enough space on the inside of the vessel to remove the insert for maintenance/after sales services. The XFM unit requires an additional 120mm / 4.7” from the rear of the mounting tube to allow the insert to be removed for maintenance. (See overall dimensions in the Appendix).

Ensure that the part of the light inside the vessel has a diameter of 100mm/ 4” around it free from any insulation material.
OceanLED recommends using a qualified installer / technician when making modifications to your vessel. Please also consult the manufacturer for more detail on modifications and installation.

If lights are assembled in a conductive or wooden hull, an Isolation Kit must be used. Contact OceanLED for additional details.

Depth/Spacing
Ideally mount your lights at similar depth levels to ensure matching colour consistency through the water. Deeper lights will look duller and possibly differ in colour compared to shallower mounted units.

Installation

INSTALLING THE LIGHT FIXTURE

Explore E2

Kit Includes

Additional items required not supplied by OceanLED:

Marine sealant – 3M 4200 or equivalent
Cable ties
Waterproof Cable Connectors / Junction Box (optional)
Allen key (5mm)
Thread lock – Loctite 243 or equivalent.

DO NOT remove the light cartridge from the mounting tube during installation. The light cartridge MUST stay fitted inside the mounting tube throughout the installation process to avoid the introduction of potential contaminants that may damage the product and void warranty. The light cartridge can only be removed for maintenance or after sales purposes and OceanLED must be contacted prior to any light cartridge being removed from the mounting tube.

OceanLED recommends dry fitting all products. When installing, be sure that the light fits the area and secures to the hull using the appropriate hardware before applying any sealant.

When applying sealant to the light fixture, use OceanLED packaging material such as the light cardboard box when placing the light on the ground face down to prevent lens damage.

Installation (Once hull preparation is complete)

Test light(s) before fitting into the hull.
If using a Delrin Isolation Kit, insert the Isolation Kit front washer into the drilled hole and apply marine sealant to seal between the Front Washer and the hull. The Front Washer is identified by a raised edge and the Rear Washer is flat.
Apply marine sealant to the rear of the mounting tube assembly’s bezel to ensure a complete unbroken seal around the light.
Make sure sealant fills in the recess groove on the reverse of the light bezel:
Ensure the light orientation is correct with the cable gland at the back positioned at the bottom (see image below) perpendicular to the waterline. If there is not enough space at the back of the light for the cable, the light orientation can be changed to the cable gland positioned at the top, perpendicular to the waterline.
Insert the complete light unit (mounting tube assembly + light cartridge) into the hull, pressing the light hard into the hull and twist slightly to spread the sealant around behind the light to ensure good adhesion. This process is made much easier if a second person is inside the hull to receive the light and install the locking equipment whilst supporting the light from the outside. Breakages due to lights falling out of the hull are NOT covered under warranty and can cause serious bodily injury as can any falling object.
If using a Delrin Isolation Kit, insert the Isolation Kit Rear washer over the mounting tube and locate it flush with the hull. The Rear washer is identified as flat.
Insert the stainless-steel compression washer over the mounting tube. The stainless-steel compression washer does not need to be flat to the hull, a slightly uneven surface can be compensated by the washer.
Place the two clamping clips together to form a circle, ensuring you pair 1 threaded and 1 non-threaded hole together. Fix the clips together using one of the longer screws provided so that the clips are located approximately halfway down the length of the screw. Locate the clips into the appropriate grooves (depending on hull thickness) on outside of the mounting tube so that the end of the screw is close to the washer. Fit the second longer screw provided into the remaining holes, fixing the two clips together. Leave the shorter screw out to connect the light to the vessel’s cathodic protection system.
Tighten the locking screws using a 5mm Allen key, applying thread lock at point of thread contact with locking ring. DO NOT over-tighten locking screws, as you could damage the mounting tube, and this will not be covered under warranty.
Once you are satisfied that the unit is fully tightened, you will notice that sealant has squeezed out from around the perimeter of the light. Using a thinner or cleaner, apply to cloth and wipe off excess sealant to leave a clean seal. AVOID CONTACT WITH LENS. If you do not see sealant squeeze out from the body, you have not used enough sealant or tightened the unit enough to the hull. Carefully examine the installation to make sure the seal you have installed on the unit is fully watertight. If in doubt, remove light, re-apply sealant and re-install.
Connect the bonding cable to the remaining screw and lock in place with shake-proof washer provided. Tighten the locking screw using a 5mm Allen key, applying thread lock at point of thread contact with the clamping clips.
BONDING: The light MUST be attached to the vessels bonding / cathodic protection system. Once fitted it is mandatory to check that there is full continuity between the vessels cathodic protection system and the outer bezel of the mounting tube assembly (see bonding schematic – Appendix Chapter 7).

ELECTRICAL INSTALLATION (12/24V DC)

Additional items required not supplied by OceanLED:

Junction box* / waterproof connectors
Sufficient cable to connect to DC Power Pack

Optional 4-Way Junction box available from OceanLED. Please contact OceanLED or your representative for further information.

Always consult a qualified electrician when connecting OceanLED light fixtures.
When connecting light units, please note that all OceanLED lights will operate within a specific voltage range. Please check the electrical information to ensure cable gauge follow the recommendations.

Never leave the bare cables unprotected. Take care to not leave the bare wire ends in bilge water before making the waterproof connections. Water deposits in the connectors and cables will cause corrosion.
Over time water can also work its way into the unit along the inside of the cable due to capillary action causing the light to fail. This will NOT be covered under warranty.
For complete instructions on DC connections, please refer to ABYC codes of practice and other applicable codes and ordinates for DC connections.

Where multiple lights are fitted, and especially on 12V systems, it is advised to use a relay system to supply the switched power to the lights, to reduce load on the switch and voltage drops caused by long cable runs to the switch location.

Depending on the model and number of lights installed, you will need to pull the correct sized power cable from the DC power source (breaker/fuse panel) to the light locations to supply constant power to the light units. It is imperative that the correct sized tinned marine grade cable is used to avoid voltage drop issues.
See Chapter 7: Appendix for recommended cable gauges.
Using waterproof Butt Splices or IP66 waterproof junction boxes, make the connections at either end of the system to attach the lights to the DC system. Make sure any heatshrink used completely encapsulates the outer wire sheath (the use of glue-lined heat shrink is highly recommended to ensure water tightness).
Never install a new light fixture then leave the vessel in the water unchecked for several days.

It is imperative that either the OceanLED supplied fuse on each power line to each light or a suitable protection device is used to protect the cable/light unit. Failure to do so will void the warranty. See table in Chapter 2: Power Consumption and Recommended Fuse values. Make sure any heatshrink used completely encapsulates the outer wire sheath (the use of glue-lined heat shrink is highly recommended to ensure water tightness).
Secure cables ensuring where the cable exits the light it is not under undue stress. Finish and test the light units BEFORE the vessel goes into the water. Never leave lights ON out of water for longer than 5 minutes followed by an off period of 1 hour.

WIRING SCHEMATIC WITH 3RD PARTY JUNCTION BOX:

FINALISING THE INSTALLATION
The Explore XFM mounting tube is constructed from corrosion resistant Aluminium Bronze and does not require further protection. The glass is pre-coated with a specialized Tritonium® coating which helps to prevent marine growth from adhering to the glass. Do not apply any additional coatings, such as foul-release products, to the front of the lens without consulting OceanLED. Failure to do so will void your warranty.

OceanLED does not recommend that bottom paint or any type of anti-fouling agent is applied to the glass and/or bezel, as damage may occur due to chemical incompatibility. If bottom painting of the bezel is deemed essential, then an area of at least 5mm should be left uncoated around the glass lens:

The protective lens sticker should be removed once all work on the vessel is complete.
Do not coat the light’s glass/lens with any product, including but not limited to clear antifouling paints or similar, without consulting OceanLED for advice. Failure to do so will void your warranty.

Do not use any un-authorised cleaning products to remove excess paint or antifoul off the glass or within 5mm of the glass. OceanLED recommends using Isopropyl Alcohol (IPA) only.

TEST YOUR INSTALLATION

Always test the lights BEFORE the vessel goes back into the water. At this final stage make sure all of the system is operational. If you have any issues, please contact your local OceanLED representative.
Never install a new light fixture then leave the vessel in the water unchecked for several days.

Never leave lights ON out of water for longer than 5 minutes followed by an off period of 1 hour.
When the vessel is placed in the water, immediately check for leaks. Note that very small leaks may not be readily observed. It is best not to leave the vessel in the water for more than 3 hours before checking it again. If there is a small leak, there may be considerable bilge water accumulation after 24 hours. If a leak is observed, you must TAKE ACTION IMMEDIATELY to prevent damage.

Operation / Maintenance

SINGLE COLOUR STROBE
To enter strobe mode, with the light on, toggle the power off then quickly back on. They should now strobe in a random pattern. The lights can be reset from strobe mode by simply turning off, waiting 10 seconds, then turn on again.

MAINTENANCE
Marine growth can build up quickly on the light and can reduce the light’s performance in just a few weeks. To help prevent this, all OceanLED lights have been coated with a specialized Tritonium® coating which helps to prevent marine growth from adhering to the glass. Lights should be cleaned with a boat brush or similar bi-weekly, or as needed to keep the lens of the light clean.
Growth varies greatly around the world and maintenance is imperative to the proper operation and longevity of the product. If heavy fouling occurs, growth can be removed from the lens using a plastic scraper and moderate pressure under water. If cleaning the lens while the boat is out of the water, wet the lens before scraping. Never scrape or try to remove barnacles from a dry lens.

Never use high pressure jet wash to clean the lens / bezel as this will damage the seals and void the warranty. Do not use harsh cleaning solvents, as they will damage the light seals and Tritonium coating.
Do not coat the light’s glass/lens with any product, including but not limited to clear antifouling paints or similar, without consulting OceanLED for advice. Failure to do so will void your warranty.

If bottom painting ensure the coating is applied as instructed in the “Finalizing The Installation” section. Failure to do so will invalidate your warranty.

LIGHT CARTRIDGE REMOVAL
Additional items required not supplied by OceanLED:

M8 Bolt
13mm Spanner (for the M8 bolt)

Before proceeding with this operation, you MUST seek permission from either the manufacturer or your OceanLED representative or you will void the warranty.

If the vessel is in water check that the front glass is present and intact. Never remove a cartridge with the vessel in water if damage to the glass lens is suspected.
Turn power off and disconnect the light cable connection from the electrical installation.

Remove the Locking Ring from the mounting tube.
To ease removal process; undo the cable gland nut to allow air to enter the unit and prevent a vacuum being created when removing the light cartridge. Failure to do so could damage the light cartridge.
Fit the M8 bolt into M8 threaded hole on the rear of the light cartridge.
Remove the light cartridge from the mounting tube by pulling the M8 bolt.

LIGHT CARTRIDGE RE-INSTALLATION
Additional items required not supplied by OceanLED:

Isopropyl Alcohol (IPA)

Before installing the light cartridge, clean the inside of the mounting tube with Isopropyl Alcohol (IPA) cleaner and let it dry. Failure to do this may introduce potential contaminants that may damage the product and void your warranty.
Lubricant substances of any kind MUST NEVER be used to ease the insertion of the light cartridge into the mounting tube as this will damage the light and void the warranty. Should any help to insert the light cartridge be needed, OceanLED recommend the use of a small quantity of Isopropyl Alcohol sprayed onto the O-Ring on the back of the light cartridge.

Inspect the mounting tube and light cartridge to ensure no contaminant (grease, debris, dirt) and/or water are present.
Undo the cable gland to act as a breather. Failure to do so will make the installation process significantly harder and could damage the light and void the warranty.
Align the light cartridge with the mounting tube. Push the light cartridge in slowly until it bottoms out against the front bezel. Please see Chapter 4 Installation.

Tighten the cable gland.
Fit the Locking Ring.
Connect the power cable and test the light. Re-check if the light is pointing the right way up.
