View the Energy CalculatorBuilt to last, designed to replace. The Prism Pro XM is unlike any downlight you’ve installed before.
Designed with sustainability in mind, this innovative, modular fire rated led downlight allows electricians to easily switch out the light engine and driver components, eliminating the need to replace entire fittings. Simply install, replace only what’s needed, and keep the rest in use. Available in downlight, anti-glare, and gimbal variants.
The modular design of the Prism Pro XM extends product lifespan significantly through easily replaceable components. When either the light engine or driver fails, simply replace the individual part rather than the entire fitting – reducing installation time and environmental impact.
The Prism Pro XM features tool-free lever terminals and clip-in housing for rapid installation. Its ultra-low profile—just 88mm diameter and 26mm height—fits shallow ceiling voids, while integrated spring clips ensure secure fixing in even the tightest spaces.
This fire rated downlight meets all UK building regulation requirements, fully tested for 30, 60, and 90-minute ceiling types to meet Part B regulations. Additionally tested to meet Part C (moisture), Part E (acoustic), and Part L (energy) requirements.
Assessed to TM66, the industry standard for lighting circularity, Prism Pro XM supports more sustainable specification. It offers CCT selection from 2700K to 6000K and power selection at 5W or 7W, combining multiple outputs in one flexible, modular downlight.
Ansell Lighting provides technical support, next-day delivery, and extensive product training. Our LIA-accredited team ensures you have the expertise needed for successful installations. Ready to get started with Prism Pro XM for your next project? Get in touch today.
