A CLEANER LOOK OVERHEAD
Choose the finish. Set the tone.
The BCM Ocean 105 Recessed LED Down Light, available through Apex Lighting, brings fixed overhead illumination to marine interiors and suitable exterior applications. Its round 105 mm trim surrounds a diffused lens, while spring mounting keeps the installation free of exposed mounting screws. Choose one of three finish and white-light combinations from the dropdown.
01 / FINISH
Coordinate with the interior.
Choose a White trim ring for a clean, light-colored finish or Polished Stainless Steel to match reflective metal fittings.
02 / COLOR
Warm White or Neutral White.
3000 K Warm White is offered with White or Polished Stainless Steel trim. 4000 K Neutral White is offered with Polished Stainless Steel trim.
03 / INSTALL
A spring-mounted recessed fit.
The three models offered here use wire springs and an 85 mm cutout. Their onboard driver operates from an 18–32 V DC supply.
THREE OPTIONS. ONE PRODUCT LISTING.
Select your finish and light color.
Each dropdown choice is a complete fixture with a fixed white-light color. Choose the combination that matches the look and feel of your installation.
| Dropdown selection | LED color | Manufacturer part number |
|---|---|---|
| White Trim Ring / Warm White | 3000 K | BCM3479-A105-20 |
| Polished Stainless Steel Trim / Warm White | 3000 K | BCM3479-A105-4 |
| Polished Stainless Steel Trim / Neutral White | 4000 K | BCM3479A105-4 |
All three choices are single-color, spring-mounted models. The light color is selected when ordering; these versions do not switch between Warm White and Neutral White.

“4-inch” describes the approximate fixture size, not the hole size. Measure the actual light before cutting, and leave additional room for the wiring, springs and any installation clearance required by the manufacturer.
PLAN THE SPACE BEHIND THE CEILING
Dimension drawing
Check both the opening and trim coverage when replacing an existing down light. Spring mounting also needs suitable material and space for the retaining springs.
CONTROL, EXPLAINED
Dimming with compatible equipment.
The Ocean 105 product sheet lists the fixture as dimmable. Apex Lighting lists DMS dimmer compatibility for the 3000 K models. Select control equipment for the exact fixture and supply before installation.
Check the complete combination
Compatibility depends on the light, power source and control method. Confirm the required dimmer and wiring for your selected part number with Apex Lighting or your installer, especially when replacing an older fixture.
The three models sold here are fixed-white lights. Dimming changes brightness; it does not add RGBW color changing or a second LED color.
READY FOR YOUR INSTALL
What’s in the box?
- 1 × Ocean 105 recessed LED down light
In the finish / LED-color combination you select.
Plan suitable DC power, circuit protection, wiring and any optional dimming equipment separately. No separate power supply or dimmer is listed as included.
PLAN BEFORE YOU CUT
Three checks for a cleaner installation.
1 / Verify the supply
These models require 18–32 V DC, making them suitable for an appropriate nominal 24 V system. Do not connect directly to a nominal 12 V circuit or household AC.
2 / Measure the opening
Check the 85 mm cutout, 105 mm trim coverage and clearance for the body, wiring and springs. Use the actual fixture to confirm fit.
3 / Confirm control and protection
Disconnect power before wiring. Follow the supplied instructions for polarity, circuit protection, connections and any dimmer installation.
IP66 is not an underwater-installation rating. Choose an appropriate marine mounting location and follow the instructions for the supplied fixture.
BEFORE YOU ORDER
Common questions
Which three models are available in this listing?
BCM3479-A105-20 is White / 3000 K Warm White; BCM3479-A105-4 is Polished Stainless Steel / 3000 K Warm White; BCM3479A105-4 is Polished Stainless Steel / 4000 K Neutral White.
Can I change between 3000 K and 4000 K with a switch?
No. These are single-color versions. Choose the required color temperature in the finish / LED-color dropdown when ordering.
Does this use a 4-inch mounting hole?
No. The current manufacturer specification gives an 85 mm cutout, approximately 3.35 inches. The trim measures 105 mm, approximately 4.14 inches.
Can I run it on a 12 V boat circuit?
Not directly. These specified models require 18–32 V DC. Confirm a suitable supply for your boat and lighting layout before installation.
Are these screw-mounted lights?
No. The three versions offered here are retained by wire springs. Screw-mounted Ocean 105 versions elsewhere in the manufacturer range are not included in this listing.
Is a remote LED driver required?
The fixture has onboard driver electronics. You still need the correct DC supply and compatible control equipment if dimming is required.
Does the 4000 K model also produce 242 lumens?
The linked sheet publishes 242 lumens for the 3000 K version. A separate lumen rating for the selected 4000 K part is not stated here.
