PureFX - Recessed

PureFX set a new industry standard for recessed lighting systems. Using Ledalite’s revolutionary MesoOptics technology, PureFX offers the perfect blend of brightness, control and energy efficiency—making happier people and a healthier environment.


The right kind of bright

MesoOptics technology makes spaces feel more natural and enables superior visual comfort by delivering uniform brightness with exceptional glare control.


Sustainable building designers and building owners benefit with dramatic energy savings—up to 20% increased efficiency and 35% energy cost-savings over conventional recessed lighting systems.

Designer’s dream

Extensive lamping options and a range of housing sizes and configurations meet the needs of almost any recessed lighting application. The petite 1’x1’ micro version is an ideal companion for corridors, meeting rooms, reception areas and other feature areas.

Maintenance made easy

Ledalite’s recessed lighting systems provide lamp and ballast access from below the ceiling without tools for quick and easy relamping and maintenance.

Exceptional Control and Efficiency

MesoOptics technology allows PureFX to have the best possible combination of lighting control and brightness with efficiencies that are almost 20% higher than other recessed lighting products.

Reduced Energy Consumption

When attempting to achieve a light level of 50 footcandles, most 2’x2’ recessed lighting systems will require two 40W TT5 lamps. PureFX requires only a single 55W TT5 lamp to meet this lighting level— a 35% reduction in lightingrelated energy costs.

See the difference


A typical recessed parabolic fixture offers superior glare control, but it creates a darker, cave-like environment with very harsh shadows and dark walls.


PureFX offers a similar level of glare control, but increases brightness levels throughout the space. This leads to softer shadows and a brighter space that is still visually comfortable.

Recessed Applications Guide

PureFX comes with a range of lamping options to suit a wide variety of lighting and energy efficiency needs. The chart to the right illustrates some of the options and their typical results.

Maintenance Made Easy

LED Luminaires

Push in the end corners of the fixture where the hinges are located.


To access the driver compartment, remove the screws on the upper reflector.


Gently lower the upper reflector and remove the LED driver.
