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)
