SL1 MR16 Sign Light

MR16 Sign Light

Precision machined lighting fixture for MR16 halogen lamps or integral LED lamp modules with drivers. Can be used for sign lighting, canopy lighting, and accent lighting applications.

  • Thick walled cap and optimized high temperature silicone O-ring placement prevents leaking.
  • Patented ‘double-taper’ locking knuckle that locks and stays locked.
  • Thick walled cap allows for more threads and larger set screw to prevent stripping.
  • Stem lengths from 6" to 48", three bend styles, and three canopy styles.
  • LED modules are field replaceable and feature replaceable lenses.
  • LED drivers utilize dynamic transformer recognition to simplify installation and patented LEDSense® thermal management to keep LED running at the optimum temperature.


    Available in machined 6061-T6 aluminum or C36000 brass.


    Machined head comes in two styles: Side Mount and Rear Mount. (See illustration on Specification Sheet for aiming capability of each head style.)


    1” diameter machined stem comes in various stem lengths and three stem styles: Straight, 180° U-Bend, and 90° Gooseneck. (See illustration on specification sheet for calculating overall projection from wall for each stem style.)


    Rotate and Lock knuckle (protected under U.S. Patents #6,966,679, #7,108,405 and #7,458,552) mounts the head to the stem and allows for adjustability. Double taper design allows fixture to hold position during aiming and ensures a solid lock when tightened. Integral LED models have a molded silicone wire seal to prevent water entry at knuckle.


    Machined caps lock in place with one 18-8 stainless steel set screw, and are sealed to the body with a high temperature silicone O-ring. Regress Lens caps have drain holes for water drainage from top of lens if mounted in the up position. ‘Flush Lens’ cap styles incorporate a stepped lens to reduce the collection of water and debris on the lens. All caps accept up to three internal accessories, held in place by a stainless steel clip. Mount Canopy Available with the following mount options: MO3 (Machined Round Canopy), MO15 (Machined Square Canopy), and MO12 (Surface Mount Powered Canopy). See mount specification sheets for more information. (Mount canopy must be mounted to an appropriate wall or junction box, in such a manner that is capable of holding the weight and torque created by the fixture. Junction box and hardware not included).


    TGIC thermo set polyester powder coat paint available in 14 standard colors. On aluminum model, finish is applied over a corrosion resistant, hexavalent chromium free, RoHS compliant coating. Aluminum model available in one additional metal finish: Clear Anodized. Brass model available in three additional metal finishes: Natural, Polished, and Aged.


    Tempered, clear lens, secured to cap with a high temperature, UV curing, silicone adhesive.
