Description
Fire Rated Dimmable LED Downlight with CCT and Wattage Selection
Collingwood DLT551500B
Collingwood H2 Lite CSP LED Downlight is a fire-rated, mains-dimmable lighting solution designed for professional installations where flexibility and long-term reliability are required. It combines switchable colour temperature and switchable wattage within a compact, fixed downlight format, making it suitable for a wide range of residential and light commercial environments.
Colour temperature selection is controlled via discreet front-facing switches, accessed by removing the bezel, allowing installers to configure the output during installation. The inclusion of a 2200K option enables a warmer, more ambient lighting effect, while higher CCT settings support functional and task-focused illumination.
