i2Systems LightLink Elevator Dimming Module, 9-36V DC, Momentary Switch Dimming, Remembers Last Intensity after Power Cycle

Overview

The i2Systems LL-101-01A is a LightLink dimming module that lets one momentary push-button switch control an i2Systems dimmable LED lighting zone on board, running from a 9-36 V DC supply (12 V or 24 V systems).

Tap the switch for on and off, then press and hold to step through brightness levels. After a power cycle, it returns to the last intensity stage, which helps when a lighting circuit is fed through a breaker, battery switch, or timer.

One module can control up to 20 compatible i2Systems LED Marine/Transit fixtures, including PRO fixtures, so you can group cabin, cockpit, or companionway lights into a single zone without adding multiple dimmers to the panel.

Key features

• 9-36 V DC operating input for common 12 V and 24 V boat systems

• Controls up to 20 compatible i2Systems dimmable LED fixtures, including PRO fixtures

• Normally-open momentary switch input: tap for on/off, press and hold to dim

• Start-memory behavior restores the last intensity stage after power is cycled

• DIM (yellow) control output with a common reference; with a shared DC common, a single DIM lead can be run to each light in the zone

• Installation guidance calls for fused power and minimum 18 AWG (0.82 mm2) wiring rated to 105°C or higher

Installation and setup

Mount the module where it stays dry and accessible for service. A common approach is placing it inside the switch box that houses the momentary dimming switch, then routing the DIM control lead out to the lights in that zone.

Power wiring is straightforward: connect +DC to Vin (red) and DC common to Common (black), with a fuse in series with the Vin feed. Disconnect power before servicing and avoid feeding it from an unprotected source.

This unit is intended for dry or damp locations, not for spots where water can collect, pool, or puddle. Keep it out of bilge areas and away from spray paths inside lockers.

Compatibility and fit

This module is for controlling i2Systems dimmable LED Marine/Transit fixtures. Verify your lights are the dimmable models intended to accept the LightLink dimming signal, and plan your zones so you stay within the supported fixture count.

The control input is built around a normally-open momentary switch, and multiple momentary switches can be wired in parallel to control the same lighting zone from more than one location.

Electrical and system integration

The dimming output is provided on the DIM lead (yellow) with a common reference on the black lead. The system uses a common ground, so the LightLink and the fixtures must share DC common for the dimming signal to reference correctly.

If you are running longer control leads, keep connections clean and well-supported so they stay reliable under vibration, and route wiring away from high-heat areas and moving parts.

Use on board

This setup fits boats where you want single-button control for a lighting zone, such as a cabin overhead group, a cockpit lighting zone, or companionway lights that need quick dimming without adding a rotary control. It also suits refits where you want the lights to come back at the same brightness after a breaker cycle.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
