LED downlight replaces traditional CFL luminaires

The forthcoming ARC Show will provide visitors with the first opportunity to see two new Cooper Lighting products that mark a significant breakthrough in the use of LED technology for commercial lighting applications.

Just launched as part of the company’s Axent brand of architectural lighting solutions, the RXD downlight is the first truly viable LED alternative to traditional compact fluorescent downlights, while the DXS spotlight offers major benefits for retail and display lighting.

The RXD downlight delivers energy savings of 35% when specified in place of the 2 x 26W compact fluorescent downlights currently in widespread use. Moreover, it achieves these savings without compromising light levels or quality of light.

At the heart of the downlight is an innovative multi-chip LED light source. Unlike conventional high-output LEDs, this technology incorporates multiple LEDs in a single package, giving increased light output in a smaller space and a wider spread of light.

Using proven heat-pipe cooling technology to transfer heat away from the back of the LED source, coupled with a high-quality driver to minimise fluctuations in current levels, the RXD achieves a maintenance-free life of 50,000 hours.

The downlight is optimised to deliver a CRI rating of greater than 80 and over 1400 usable luminaire lumens – not to be confused with LED source lumens – while drawing only 37W.


Providing a choice of 2900K warm white or 5000K cool white illumination, the RXD is available in round or square versions and can be specified as trimless or with a choice of white, silver or chrome bezels. It is a lightweight and compact fitting with a body height of only 86mm, which makes it ideal for use in restricted ceiling voids.

The Axent DXS spotlight, which employs the same LED and thermal-management technology as the RXD downlight, offers an ideal solution for retail and display lighting applications because no heat is generated from the front of the unit and there is no UV light to contend with.

Designed to be installed directly into most common types of 3-circuit track, the spotlight is extremely easy to set up and adjust. It can be moved through 360 degrees horizontally and 180 degrees vertically, with both positions locked by a single lever; no tools are required.

Featuring distinctive modern styling, the spotlight is available in single and twin versions - finished in white, silver or black - with a choice of beam angles and either warm white or cool white colour temperatures.
