4000K Cool White Illumination

The ALD425-W40 produces a 4000K cool white light, making it particularly suitable for professional environments where clean and practical general illumination is required.

4000K is widely suited to working spaces such as offices, classrooms, corridors, meeting rooms and commercial premises, providing a crisp white appearance without moving into the much cooler appearance associated with higher colour temperatures.

For projects requiring a professional general-purpose commercial lighting colour, the 4000K ALD425-W40 is a versatile option.

Direct Backlit LED Technology

The Kosnic Alden 4 uses a direct backlit LED design to deliver efficient illumination across the panel.

Rather than relying solely on edge lighting, the backlit construction works with the luminaire's wide-angle optics to distribute illumination across the surface.

This provides the clean, uniform appearance expected from a modern LED panel while making the Alden 4 a practical replacement for older commercial ceiling luminaires.

Wide-Angle Optics for Even Light Distribution

The Alden 4 incorporates wide-angle optics specifically designed to achieve even light distribution across the surface of the luminaire.

Consistent illumination is especially useful in commercial environments where several panels may be installed across a ceiling grid.

When appropriately positioned, multiple panels can provide a clean and uniform general-lighting scheme throughout the room.

25W Energy-Efficient LED Panel

With a rated power of 25W, the ALD425-W40 provides an energy-efficient LED lighting solution for suitable indoor applications.

It offers a modern alternative to older fluorescent ceiling fittings, combining LED efficiency with the familiar panel format commonly used in commercial suspended ceilings.

For refurbishment projects, this can provide a straightforward route for upgrading older lighting installations to LED technology.

Flicker-Free Driver Supplied as Standard

Kosnic supplies the Alden 4 panels with a flicker-free driver as standard.

This makes the ALD425-W40 especially appropriate for offices, educational buildings and other frequently occupied spaces.

Designed for In-Lay Ceiling Applications

The Alden 4 has been developed as an easy-to-retro replacement for in-lay ceiling tile fittings.

Its panel format makes it particularly useful for suspended-grid ceiling installations commonly found throughout commercial and public-sector buildings.

For refurbishment projects, the design allows outdated ceiling-tile lighting to be replaced with modern LED panel technology while maintaining a clean and familiar ceiling layout.

Ideal for Office Lighting

The combination of 4000K cool white light, wide-angle optics and uniform illumination makes the ALD425-W40 particularly suitable for office environments.

It can be used for general lighting across open-plan offices as well as meeting rooms, reception areas, administrative spaces, corridors and other appropriate areas.

The understated panel format also integrates neatly into modern commercial interiors.

Ideal for Educational Environments

Schools, colleges and other educational buildings can also benefit from the Alden 4's broad and consistent light distribution.

The 4000K colour temperature provides a practical light appearance for classrooms, staff areas, libraries, corridors and general teaching spaces, while the included flicker-free driver adds to its suitability for spaces occupied throughout the working day.

Commercial LED Retrofit Solution

The ALD425-W40 is well suited to commercial LED upgrade and refurbishment projects.

Older in-lay ceiling fittings can be replaced with a modern backlit LED panel without abandoning the familiar ceiling-grid format.

This makes the Alden 4 useful for contractors upgrading office buildings, schools, shops and other commercial properties from traditional lighting technologies to LED.

Clean, Professional Appearance

LED panels are designed to integrate discreetly into ceiling systems, making them particularly useful where a clean and uncluttered appearance is required.

The ALD425-W40 combines this streamlined format with uniform illumination, helping create a professional finished installation suitable for a wide variety of commercial interiors.
