Bluefin LED Underwater lights.
GW20IFM/GW48CCIFM Installation manual.
Thank you for choosing Bluefin LED underwater lights, our products have been designed and tested
to ensure optimum performance and longevity is maintained.
All Bluefin Led lights are water tested so please be aware there may be moisture present on the light.
This light is designed for use on fibre glass hulls only and not to be mounted to any Metal hull or
your warranty will be void. If you are mounting to a Metal hull boat a Delrin isolation sleeve can be
purchased.
Please ensure that your product is installed as per our instructions below, failure to do so may
invalidate your warranty.
If you are installing a GW48CCIFM please refer to the Driver instructions for electrical installation.

Warnings:
•Do not attempt to install the lights whilst the boat is in the water.
•Ensure that the correct voltage is used for the light.
•Ensure that an in line fuse is installed with the correct fuse rating per the light installed.
•Ensure that the supplied gel connector is used to make a watertight connection or your
warranty will be Void.
•Do not remove the inline HYDRO LOCK or your warranty will be void.
•Do not hold the light by the cable.
•Do not use abrasives on the lenses.
•Do not stare into the LED light at close proximity
•Lights must be mounted a minimum of 300mm from any Anodes.
•Do not mount lights directly underneath Anodes.
•Do not bond directly to Anodes.
•Only bond to the vessels DC bonding system & ensure all connections are in perfect
condition & are regularly checked.
•When mounting on any type of conductive surface or hull material full electrical isolation
between the light & mounting surface must be provided & maintained at all times
throughout the lights life.
•Failure to adhere to any of these requirements will invalidate warranty.
•As Galvanic currents & corrosion are external factors any type of damage caused by galvanic
affects are not covered by BluefinLEDs warranty policy.
Tools required for installation:
•101mm(4”) hole saw
•Drill
•Marine sealant 3M 5200/4000UV, Sika flex 291i or equivalent (do not use 3M 4200)
Installation:
For optimum affect effect the light should be positioned between 8-12” (200-300mm) below the
water line and at a 90 deg angle. Recommended spacing from 3-3”(1mtr) to 5-11” (1.8mtrs) between
the lights.

Drill a 101mm (4”) hole for the light access through the hull, ensuring that there are no obstructions
internally in the hull.
Key the area to where the light is to be mounted with abrasive sand paper to ensure there is a clean
area for the marine sealant to bond too.
Apply marine sealant to the rear of the light on the circumference of the light and around the base of
the tube to ensure a complete continuous bead of sealant is applied in both areas. (See fig 2)
Feed the light through the hole and clamp internally in the hull using the clamping ring and washer
supplied ensuring a tight fit using nuts and bolts supplied. (See fig 3 and 4)
Wipe off any excess sealant and ensure the light is seated correctly without any gaps in the sealant.
(It is good practice to have excess marine sealant to clean off as this can ensure that there is a water
tight seal to the hull)
Electrical connection:
Ensure you use the IP68 GEL CONNECTOR supplied to connect to the boats wiring or you Warranty
will be void (fig 6/7).
You will notice an inline HYDRO LOCK attached to your cable (Fig 1). If this guard is removed you
warranty will be void
It is advised that if installing GW16 models no more than 8 lights should be installed on your low
voltage system.
If installing more than 8 GW16 models we suggest using our Mains Upgrade Power Supply (contact
your local Bluefin Led dealer for further information)
It is advised that if installing GW20 or GW48CC Models no more than 6 lights should be installed on
your low voltage system.
If installing more than 6 GW20 or GW48CC models we suggest using our Mains Upgrade Power
Supply (contact your local Bluefin Led dealer for further information)
Care should be taken when planning your electrical feeds/cables to the lights so as to ensure voltage
drop between the batteries or power supply is minimised, on 12V systems this is especially important
as the lower system voltage means a high current requirement which in turn means the potential for
more voltage drop in the cable runs & connections.
If the cable gauge & connections are not sufficient for the lighting load attached you may experience
incorrect operation of the lights & intermittent illumination as the supply dips below specification.
Please see the wire gauge guide attached to the instruction manual.
For help with calculations always consult with a qualified professional or contact Bluefin LED directly.

Attach the light cable to the VDC power on the boat ensuring that you use the in line fuse supplied
connected to the positive(red) wire, ensure that you use the heat shrink provided to create a water
tight fit into the fuse holder. (See fig 5)
Ensure that an earth bond cable is attached to the earth bolt on the locking ring and is attached to
the earth bonding system on the boat. (See fig 3)

Warnings:
•Do not attempt to install the lights whilst the boat is in the water.
•Ensure that the correct voltage is used for the light and Driver.
•Ensure that the in line fuse is installed with the correct fuse rating per the Driver installed.
•Ensure that the supplied gel connector is used to make a watertight connection or your
warranty will be Void.
•If you wish to connect your Colour change lights and drivers to your own DMX Controller
please contact BluefinLED beforehand for further advise.
Installation:
Electrical connection:
•Ensure that the supplied gel connector is used to make a watertight connection or your
warranty will be Void (see fig 6/7)

fuse supplied connected to the positive(red) wire, ensure that you use the heatshrink
provided to create a water tight fit into the fuse holder. (see fig 2)
•Plug the Light cable connector to driver as per Fig 1 aligning the white lines on the
connectors to ensure the connector pushes home correctly.
•Plug the DMX controller cable (if supplied fig 3) into the first driver DMX IN connector as per
Fig 1.
•Plug the DMX Interlink cable (Fig 4) into the DMX OUT connector on the first driver Fig 1.
•You can now daisy chain the drivers using the DMX Interlink cables going from the OUT DMX
to the IN DMX on the next driver.
•When completing a circuit you must plug the DMX Terminator plug (Fig 5) into the last
drivers DMX OUT to complete the circuit.

After installation ensure again that the light is illuminated correctly before the boat goes back into
the water and you remove the lens label.
After you boat goes back into the water check internally for water tightness around where the light is
installed.
The light has internal indicator Led’s for fault finding, these are as follows:
•Over voltage will flash red.(check the voltage to the light)
•Under voltage will show a constant red. (check the voltage to the light)
•Over temperature will show amber.(allow the light to cool down and check if submerged)
Maintenance:
Regularly check the installation for water tightness
Only clean the light with a soft bristle brush
