Eterna 25W LED Commercial Recessed Downlight 0-10v Dimmable 3-CCT – COMRCS25 (Cutout 150mm - Overall Diameter 170mm)

The Eterna COMRCS25 is a 25W dimmable COB LED recessed downlight from Eterna's commercial colour-selectable range, designed as a straightforward retrofit solution for commercial lighting upgrades. With three switchable colour temperatures built into a single fitting, it reduces the need to stock multiple SKUs for different areas of a project, while still delivering strong light output and energy efficiency.

Three colour temperatures, one fitting

This downlight offers a choice of 3000K, 4000K, or 6000K colour temperature, selectable on-site to suit the application — whether that's warm white for hospitality and retail, neutral white for offices, or cool daylight white for industrial and utility spaces. Luminaire output ranges from 2,490 to 2,580 lumens depending on the colour temperature selected, giving an efficacy of up to 100–103 lm/W.

0-10V dimming for flexible control (*optional) 

Built-in 0-10V dimming allows this downlight to integrate into commercial lighting control systems, supporting smooth light level adjustment to suit occupancy, daylight harvesting, or scene-setting requirements. A 90-degree beam angle provides broad, even coverage, making it well suited to open-plan offices, retail floors, and similar commercial spaces.

Durable construction for demanding use

Built with a die-cast body and polycarbonate (PC) diffuser, this downlight is constructed to handle sustained use in commercial environments, with an IP54 rating offering a useful degree of protection against dust and moisture. It carries a CRI of 80 for good colour rendering, and is rated for 45,000 hours of average life alongside 15,000 switching cycles, supporting long-term, low-maintenance performance even in higher-traffic installations.

Backed by Eterna's 5-year manufacturer warranty, this downlight is built to deliver dependable service well into the long term.
