Imtra Sigma Large PowerLED Downlight, 10-40V AC/DC, Warm White

Overview

The Imtra ILIM32120 is a Sigma Large PowerLED recessed downlight with a stainless steel trim ring and warm white illumination for marine lighting installations. Operating on 10-40V AC/DC, it consumes 5W while producing 197 lumens at a 2900K color temperature. Its 83-degree beam provides broad illumination for cabins, salons, and other onboard spaces.

The Sigma Large features a 4.35-inch diameter trim ring that accommodates larger ceiling openings, making it suitable for replacing existing recessed fixtures. Its two-wire dimming capability allows compatible DC installations to retain existing wiring and certain halogen dimming controls.

Key features

• Stainless steel trim ring with coated aluminum housing and acrylic polymer lens.

• IP65 protection against dust and water jets.

• 83-degree beam angle for wide-area illumination.

• Compatible with 12V, 24V, and 32V marine electrical systems.

• Two-wire dimming with compatible DC dimming controls.

• Spring or screw mounting for recessed installation.

• 50,000-hour rated LED lifetime at 70% light output.

Installation and mounting

The recessed fixture accommodates ceiling cutouts from 2.56 to 3.42 inches (65 to 87 mm) and requires 0.90 inches (23 mm) of recess depth. Its larger trim ring covers the mounting opening, supporting retrofit installations where an existing cutout needs to be concealed.

Spring mounting is suitable for compatible ceiling panels, while screw mounting provides an alternative for harder mounting surfaces. The installation method should be selected according to the mounting surface and location.

Electrical compatibility and dimming

The integrated electronics support DC power systems and low-voltage AC supplied by compatible magnetic transformers. Dimming is available on DC power through compatible Intervolt or DMS dimming systems using the existing two-wire circuit. AC operation does not support dimming.

Warranty terms, coverage, and duration are set by each manufacturer. Issues involving defects, repairs, or replacements must be addressed with the manufacturer’s support team. When available, the warranty period is listed on the product page. If it is not shown, contact us or the manufacturer for details before purchasing.

To start a claim, the customer must contact the manufacturer and follow their process. Keep your proof of purchase and original packaging, and register the product if the manufacturer requires it, as these are often needed for warranty service.
