PROTEON™ SL Linear LED High Bay

by Lithonia Lighting

  • DesignLights Consortium®
The PROTEON™ SL LED luminaire offers commercial building owners, retailers and institutions an innovative, continuous-row solution that better utilizes light to emphasize areas of focus while reducing energy. Using custom optics, the luminaire can provide unparalled uniformity and achieve a horizontal-to-vertical light ratio not attainable through previous technologies. Occupancy and photocell sensing, along with an emergency back-up accessory, are seamlessly integrated using engineered modules to provide maximum controls flexibility in a non-obtrusive form factor.


Extruded housing and heat sink made from 6063-T5 aluminum allows for superior thermal management to reduce both LED and driver temperatures. Clear anodized finish is standard to resist scratching, corrosion and provide refined appearance. The joiners and modules are made from die-cast, zinc alloy which reduces electro-magnetic interference (EMI) and offers improved thermals over alternative materials. Joiners and modules are painted with baked enamel; five-stage iron phosphate pre-treatment ensures superior adhesion.


Proprietary lensing engineered using precision-molded acrylic. The lenses work together with die-formed reflectors utilizing highly reflective WhiteOptics™ coating to improve light on task. Optical patterns range from aisle-specific to open area distributions. Pixelation is eliminated through the use of lenticular ribs on each lens in combination with semi-diffuse overlay inside the optical chamber.


Thermally protected, high-efficiency driver(s) standard with 0-10V dimming down to 10%. Each 4’ or 8’ rail contains one driver. LED light engine features OSRAM Duris E5. 25W LEDs which are connected using mating connectors to eliminate wiring inside optical chamber.
