The Collingwood Lighting THL3T Thea Lite CSP LED Downlight is a powerful and efficient lighting solution designed for larger commercial spaces such as offices, retail environments, educational facilities, and healthcare settings. Delivering an impressive 2200–2400 lumens from just 20W, this high-performance downlight offers excellent light output while maintaining energy efficiency.

Equipped with CCT selectable technology (3000K, 4000K, 6000K), the THL3T allows installers to easily adjust the light colour to suit different applications, from warm ambient lighting to bright, task-focused illumination. Its UGR ≤19 low-glare design ensures visual comfort, making it ideal for environments where reduced glare is essential, particularly in areas with screens or prolonged occupancy.

The fitting features an IP54 rating from below, making it suitable for a wide range of internal applications including washrooms and circulation areas.

With an ultra-slim profile, the THL3T is perfect for installations with limited ceiling void depth.

Designed for convenience, the downlight includes plug-and-play connectors for quick installation and is compatible with multiple dimming options including mains dimming, 0–10V, DALI-2, and push dim systems. Built with durable aluminium and polycarbonate construction and offering a long LED lifespan, the Thea Lite CSP range ensures reliable, low-maintenance performance in demanding commercial environments.
