What's included

• Lumishore 20" Curved Light Bar — White
• Two stainless-steel adjustable mounting brackets
• Two bracket drill jigs
• Full hardware kit: M6 hex bolts, flat washers, spring washers, nylon insert nuts, flat spreader plates

Best fit

Best for smaller center-consoles, walkarounds, and bay boats (under 30 ft) that need high-output white bow or forward illumination on a T-top, helm roof, or bow platform without operator glare.

Why choose this light bar

• 15,000 verified fixture lumens: 40 × 10 W white HICOB LEDs produce 15,000 measured fixture lumens (33,750 total) — real-world output, not theoretical rated watts.
• 9°–20° letterbox beam: the ultra-narrow vertical spread (9°) sweeps 20° horizontally, pushing a crisp white wall of light ahead of the bow without blinding the helm.
• IP68 & marine-grade construction: powder-coated aluminium housing with a Makrolon polycarbonate lens; sealed and tested for permanent marine exposure.
• 12 V and 24 V compatible: 10.5–31 V DC internal driver operates on either system; draws 12.8 A at 12 V or 6.2 A at 24 V.
• Ecosystem-ready: wires to a simple on/off switch for standalone use, or integrates into the ECLIPSE or EOS-LUX Command Center for MFD dimming, zone control, and scenes.
• Authorized dealer support: buy from MyGreenOutdoors with Garmin- and Lumishore-focused product help and fast shipping on qualifying orders.

Key specifications

Compatibility & control

The 20" Curved Light Bar operates standalone from any customer-supplied on/off switch wired to a 12 V or 24 V fused circuit. For dimming, zone grouping, and MFD integration, it pairs with the Lumishore ECLIPSE Command Center (12 V only) or EOS-LUX Command Center (10.5–31 V). The EOS-LUX system connects to supported Garmin, Simrad, B&G, Raymarine, Furuno, Humminbird, and Lowrance chartplotters.

• Standalone switch control — simple 2-wire on/off from any toggle or rocker switch
• ECLIPSE Command Center — 12 V dimming and zone control; 3-wire connection
• EOS-LUX Command Center — full MFD integration (Garmin GPSMAP 7x2/9x2/12x2/7x3/9x3/12x3 and others); requires MFD Conversion Cable (010-14453-00 for Garmin, 010-14454-00 for Simrad/B&G)

Frequently asked questions

What size light bar do I need for my boat?
As a general guideline, the 20" bar suits vessels under approximately 30 ft; the 30" fits 30–40 ft boats; the 40" suits 40–50 ft; and the 50" is recommended for larger sport-fishing and offshore vessels. Actual selection also depends on mounting location and desired light intensity.

Can the Curved Light Bar be used with a dimmer?
Yes. For dimming, connect the bar to the Lumishore ECLIPSE Command Center (12 V) or EOS-LUX Command Center (10.5–31 V). The bar does not support standard resistive dimmers — use only Lumishore control systems.

Is the 20" bar compatible with both 12 V and 24 V systems?
Yes. The internal driver accepts 10.5–31 V DC, making it compatible with both standard 12 V and 24 V vessel electrical systems. No additional converter is needed.

Does the light bar integrate with my Garmin chartplotter?
Yes, with the EOS-LUX Command Center and the Lumishore MFD Conversion Cable for Garmin (010-14453-00). Supported plotters include the GPSMAP 7x2 Plus, 9x2 Plus, 12x2 Plus, 7x3, 9x3, 12x3, 15x3, 16x3, 84xx, 86xx, 90xx, 92xx series, the 8700 Black Box, and others. The bar also works with the ECLIPSE Command Center for non-MFD installations.

What is the 9°–20° letterbox beam and why does it matter?
The letterbox beam is very narrow vertically (9°) but wider horizontally (20°). This shape projects light forward over a broad arc without angling upward to scatter back toward the helm, eliminating the forward glare that wide-angle flood lights create on T-top boats.

What fuse size should I use?
Lumishore installation guidance calls for each circuit to be individually fused per ABYC standards. At 12 V with a 12.8 A draw, a 15 A fuse (or nearest appropriate rating) on a dedicated circuit is appropriate; at 24 V, a 10 A fuse.

What's the warranty?
Lumishore covers the Curved Light Bar with a 3-year warranty. MyGreenOutdoors is a Garmin and Lumishore authorized dealer and can assist with warranty claims.
