GDH Series: The Ultimate Architectural LED Downlight System
The GDH Series is a comprehensive architectural LED downlight system designed to provide a unified lighting language for entire projects. With an extensive power range from 7W to 50W, a variety of Geometric Silhouettes, and Multi Lighting Heads options, GDH allows you to maintain consistent light quality across spaces with different ceiling heights and aesthetic requirements.
Crafted from high-grade aluminium for efficient thermal management, the GDH series is the professional choice for luxury hospitality, high-end retail, and premium residential environments.
-
Modular Versatility: Available in single, double, triple, and quad-head configurations to meet diverse lumen output requirements within a unified aesthetic.
-
Precision Directional Lighting: Each lamp head features an independent tilt/rotation mechanism (if applicable), allowing for multi-angle accent lighting from a single recessed point.
-
Ultra-Low Glare (UGR < 16): Engineered with a deep-recessed square reflector system to ensure maximum visual comfort and a premium “hidden light” effect.
-
Scalable Illumination: Perfect for high-ceiling environments or areas requiring high-density light without cluttering the ceiling with multiple individual fixtures.
-
Seamless Architectural Integration: Choose between Trimmed (flanged) for easy installation or Trimless (plaster-in) for a minimalist, integrated ceiling look.
Multi Lighting Heads Option, Four Aesthetic Profiles for Complete Design Freedom
Why clutter your ceiling with multiple individual holes when you can scale up seamlessly? The GDH Series extends into 2-Light, 3-Light and 4-Light linear spotlight modules to tackle the challenges of high-traffic commercial spaces, luxury retail layouts, and expansive hotel lobbies.

Moving beyond the precision of our single and double fixtures, the GDH Triple and Quad-Head configurations are engineered for spaces that demand higher lumen density without compromising on minimalism.
While the double-head is perfect for intimate zoning, the 3-light and 4-light linear matrices allow lighting designers to wash larger vertical surfaces, illuminate grand corridors, and achieve powerful accent lighting in double-height ceilings—all from a single, unified architectural cutout. It’s not just more light; it’s structural lighting at a grander scale.

FAQ for GDH Multi-Head series
Q: Can I mix different color temperature in a single double-head or triple-head fixture?
A: Yes. Since each head is an independent module, we can customize the color temperature for each individual light source within one housing to suit your specific project needs.
Q: Is it possible to control the heads separately?
A: Absolutely. We can configure the wiring to allow independent dimming or switching for each head, or synchronize them via a single DALI address.
Q: Do you provide the plaster-in frames for the trimless version?
A: Yes, the trimless GDH models come with a dedicated mud-in flange designed for seamless integration with standard gypsum board ceilings.
