Run-length and manufacturer assumptions
The editable example uses 3.048 m (10 ft) runs unless a shorter run is stated. Metric overviews round these to 3 m. Adapt the parts and lengths to your installation before choosing cable and protection.

Supporting parts
- 6.1 m total of 1.5 mm² (16 AWG) marine cable
- Terminations for 1.5 mm² cable, matched to the equipment's screw terminals, leads or studs
- 1.25 A fuse and holder on the positive run
- Heat-shrink, strain relief and terminal boots sized to the cable
Check stud sizes, fuse type, run length and how warm the space gets against the gear you actually have before you order.

Choose the single-colour X4 wiring
This entry covers the Ultra White X4, not the larger X8/X16 or an RGBW installation. The manual gives 0.8 A at 12 V and 0.4 A at 24 V, with 10 W maximum nominal consumption. The 12 W figure in the adjacent table column is a power-supply sizing allowance that includes reserve; it is not the light’s specified battery load. The catalog’s 0.8 A planning value is for nominal 12 V operation.
Fuse each light and seal every joint
For this single-colour version, connect red to switched positive and black to negative. Fit the specified 1.25 A fuse for each light; do not replace several individual fuses with one oversized branch fuse. Select the common supply and switch/relay for the combined load and route length using the manual’s cable tables. Keep the supplied cable and all joins supported and watertight, with the seal enclosing the outer sheath. Bare cable ends must never be left in bilge water, even while installation is unfinished.
Prepare the underwater mounting surface
Use a clean flat mounting surface and follow the hull-material instructions, including the appropriate isolation arrangement for conductive hulls. The manual illustrates mounting with the top of the light approximately 4–8 inches below the waterline and typical 2–3 foot spacing. Drill and seal the cable penetration as specified. Apply an unbroken marine-sealant barrier around the light and cable entrance; tighten the mounting screws by hand as directed rather than crushing the fitting with power tools.
Test before launching and inspect afterwards
Check polarity, individual fuses and switching before entering the water. Disconnect power before connecting or disconnecting light wiring. After launching, inspect the penetration and surrounding area immediately for leaks and repeat checks rather than leaving a new installation unattended. Keep the lens clean using the permitted methods; abrasive cleaning can damage its coating. Uneven apparent brightness can also result from depth, water clarity and bottom reflection, so verify wiring and mounting conditions before assuming the LED unit has failed.
