D421 SLIMLINE PANEL RECESSED LED DOWNLIGHT
D421 is a versatile ceiling recessed LED downlight range designed for general-purpose lighting across residential and commercial projects. Its slimline profile makes it particularly suited to shallow ceiling cavities and restricted ceiling spaces, providing a clean, low-profile finish without compromising performance.
The D421 features selectable (switchable) CCT LED technology, allowing installers to choose colour temperature on site to suit project requirements. Moreover, the range is available in multiple sizes and outputs up to 40W, making it suitable for everything from standard room lighting to higher-output commercial applications.
Dimming options include DALI and phase dimming, ensuring compatibility with a wide range of lighting control systems. Tunable white, special finishes, and custom configurations are available on request, offering flexibility for architectural or project-specific requirements.
The D421 is a practical, adaptable solution for contractors and designers seeking a reliable, efficient recessed LED downlight for residential builds, fit-outs, and commercial installations.
