Voice - Linear Surface

From the center of the building to the corner office, everyone can have the same light, the same comfort, the same Voice. Ledalite introduces Voice, a new ergonomic lighting solution that uses a single design aesthetic to handle virtually every situation.


Creative freedom

Take your pick: suspended, surface mount,  or wall mount luminaires. Voice can fit almost any building and adapt to almost any ceiling without compromising lighting quality, energy efficiency or design continuity.

Stunning aesthetics

Crisp lines, modern highlights and unique luminous aesthetics blend in with the space. Voice has a clean look and a low-profile design that shows refinement and style.

Unbeatable performance

By combining innovative optical design with exclusive MesoOptics® technology, Voice delivers industry-leading distributions for all kinds of indoor environments. Voice offers a mostly direct fixture for open ceilings; unprecedented direct/indirect performance for low ceilings; or a wall mount fixture for narrow continuous spaces like hallways.

Industry-leading close-to-ceiling performance

Excellent results with fewer fixtures

Voice achieves an incredibly low peak candela angle. As a result, fixtures can be spaced up to 16' apart with a 6" drop and still achieve less than 9:1 ceiling uniformity. You can create a balanced luminous environment in any space with smooth gradients of light on the ceiling, fewer fixtures and less energy.

Direct/Indirect with an 8' ceiling–it can happen

Voice can provide all the benefits of quality direct/indirect lighting with a drop from the ceiling as small as 3". Quite simply, a low ceiling no longer means a designer needs to compromise on lighting decisions.

Exceptional Control and Efficiency

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



Maintenance Made Easy

Push up on the center channel and then slide the lens frame to the side.

Gently lower the door. The hinge system allows you to access the inside without having to step off the ladder.

The door swings out and away providing easy access to the lamp and ballast.



Voice Surface Mount is now available in both the Linear version of Voice (73) and the Discrete version of Voice (98).
