Collingwood THLB3T Description

The Collingwood Lighting THLB3T Thea Lite CSP LED Downlight is a powerful and stylish commercial lighting solution, designed to deliver high-performance illumination in demanding environments. Producing 2200–2400 lumens from just 20W, this energy-efficient downlight is ideal for large offices, retail spaces, hospitality settings, and public buildings.

Finished in a contemporary black bezel, the THLB3T adds a modern, architectural touch to interior spaces, making it perfect for projects where lighting design plays a key role in the overall aesthetic. The integrated CCT selectable function (3000K, 4000K, 6000K) allows installers to customise the lighting output to suit different applications, from warm ambient tones to bright, task-focused illumination.

Designed for comfort and compliance, the fitting features a UGR ≤19 low-glare design and a TP(a) rated diffuser, ensuring smooth, even light distribution with reduced glare—ideal for workplaces and environments with prolonged occupancy. The IP54 rating from below makes it suitable for a wide range of internal applications, including washrooms and circulation areas.

With an ultra-slim profile, the THLB3T is well-suited for installations with limited ceiling void space, while plug-and-play connectors allow for fast and efficient installation. Built with durable materials and offering a long LED lifespan, the Thea Lite CSP range provides a reliable, low-maintenance lighting solution for modern commercial projects.
