i2Systems Apeiron Pro A503 LED Downlight, Spring Mount, 3W, IP67

Overview

The i2Systems Apeiron A503 is a 3W LED downlight with spring clips for quick mounting in overhead panels on boats. It runs on 9-30V DC and throws a wide 120° beam, making it a straightforward fit on both 12V and 24V lighting circuits.

Output is about 150 lumens (typical) and the lens uses tempered glass with a diffuser, so the light looks smooth from normal viewing angles. The housing uses an anodized aluminum body with a stainless trim, and the fixture is sealed to IP67 for wet areas and washdowns.

Configurations differ by trim shape, white tone, and finish, so you can match the cutout style and the look of your headliner without changing the basic electrical requirements.

Key features

• 3W downlight with about 150 lumens (typical) and a 120° beam for even spread
• 9-30V DC input for 12V and 24V systems
• IP67-rated sealing for wet locations and washdowns (not for submersion or standing water)
• Spring-clip mount sized for a 2.75 in (70 mm) cutout
• Requires about 1.37 in (35 mm) clearance behind the mounting surface for the 3W A503 body
• Stainless trim with anodized aluminum housing and a tempered glass diffuser lens
• Two-wire on/off with red (+) and black (ground), plus a yellow control lead when dimming is used
• Warm white (3000K), neutral white (4000K), or cool white (5700K) depending on configuration, with warm white offered in a 90+ CRI option

Variants

This downlight is offered in multiple configurations under the Apeiron A503 range, while keeping the same 3W spring-mount fixture and 9-30V DC electrical requirements.

Across the options, the trim shape can be round, square/round, or square/square. White tone varies between 3000K warm white, 4000K neutral white, and 5700K cool white, and trim finishes in this set include polished chrome and white.

Installation and setup

The spring-clip body seats into a 2.75 in (70 mm) cutout. Before cutting, confirm you have about 1.37 in (35 mm) of clearance behind the panel for the housing, plus space for a dry connection point where the leads can be terminated.

For basic on/off control, connect red to DC positive and black to DC negative. The yellow lead is used when dimming control is added; if you are not dimming, cap and secure it so it cannot short or wick moisture into the wiring space.

Electrical and system integration

Because input is 9-30V DC, the fixture can be used on typical onboard DC busses without a separate driver. When dimming is integrated, keep the control signal at or below 30V DC and route the control lead away from high-current runs to reduce noise in the dimming response.

Compatibility and fit

The IP67 seal handles spray and routine washdowns, but it should not be installed where it can sit in standing water or be submerged. This is especially important in low spots under coamings or near scuppers where water can pool.

Trim style affects the finished look and how well the light hides existing cutouts. Round trim blends into soft headliners, while the square options suit modern interiors and can help cover slight imperfections from a refit.

Use on board

Common placements include cabin overheads, pilothouse soffits, hardtops, arches, and cockpit seating areas where you want a wide pool of light without sharp hot spots. It is a good match for boats upgrading older downlights while staying on a simple switched circuit and keeping power draw low.

Maintenance and care

Rinse the trim and lens with fresh water after salt exposure and wipe with a soft cloth. Avoid abrasive cleaners on polished finishes, and occasionally check that the spring clips remain secure and that sealing surfaces stay clean.

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.
