brighter than ever, the new Engine 50

Plus we offer three additional specialist engines:


Remember how our first downlights used halogen bulbs which became warmer when they dimmed?  Now you can once again get the same look to create the cooler light of 2700K during the day and the cosy feel at night with down to 1800K with our Ambidim 50 Engine. These engines also incorporate a high 95 CRI.

Ambidim from cool to warm the new engine can be tailored to your scheme

The TRUE 50 takes the full spectrum of light to a new level.

It incorporates a new LED which mimics natural daylight to bring the full spectrum quality of natural light into the home. The high-fidelity spectral output of TRUE 50 creates stunning environments with the top colour rendering and excellent TM30 metrics. These engines incorporate a high 98 CRI.

The TUNE 50 is a truly bespoke engine which allows you to select the exact colour temperatures you wish to tune your lighting to.

This specialist engine creates an adaptable light which taps into the powerful emotional elements of light and colour to influence experience, well-being and human emotion. The smart tuneable white technology can mimic the natural spectral variation of sunlight with time of day to improve alertness and productivity, aligning with the human circadian rhythm and promoting health and wellbeing. It also enables increased flexibility to create warmer lighting environments while maintaining brightness.
