Description Item

Housing

  • Extruded aluminum profile in a 0.080-inch wall thickness.
  • Maximum length of each linear component is 12-ft.
  • 18GA steel ends are provided where needed at row termini.
  • A one-piece 14GA galvanized steel joiner/aligner bracket is provided for each joint between housings.
  • Internal cold-rolled steel components.
  • Housing intended for recessing into drywall type ceilings systems.
  • Trimless housing for plaster-in or overlapping flange trim. See ceiling types section.
  • A custom formulated non-glare matte-white polyester powder coating provides an extremely durable and long lasting finish.

Diffusers

  • Seamless fit diffusers. Flawless and consistent end-to-end fit.
  • Standard diffuser: extruded from custom formulated high transmission white acrylic material. Allows maximum light transmission while eliminating pixilation and hot spots.
  • Optional diffuser: extruded from acrylic smooth opal material. Offers a more esthetically white appearance. Note: reduces performance by up to 25%.
  • Smooth finish on both diffusers compliments the architectural elements.

LED Modules

  • High performance linear configured LED module boards.
  • Each board consists of multiple mid-power, high efficacy LEDs in a precise layout eliminating the need for supplemental heat sinking.
  • The boards produce an even and diffuse light which maximizes optical efficiency.
  • Compatible with the dimming performance of the LED driver.
  • Color temperatures available 80 CRI: 3000K, 3500K and 4000K. Upon request: 5000K.
  • Color temperatures available 90 CRI: 2700K, 3000K, 3500K and 4000K.

LED Drivers

  • Factory programmable constant current LED power supply.
  • Multiple standard drive current outputs (factory set by Mercury) are cataloged with their corresponding lumens-per-foot offering. Upon request, custom drive current outputs and lumens-per-foot options are available.
  • Note: Certain cataloged lumens-per-foot offerings may be provided with a non-programmable constant current LED power supply at Mercury’s discretion. Contact factory if critical.
  • Universal voltage input, 120V-277V, 50HZ-60HZ.
  • Specification grade dimming down to 1% on 0-10V dimming controls.
  • Lutron drivers available: LDE1 and LDE5 series. (Limited to 625 Lumens per foot packages).

Standby Lighting Options

  • Self contained module, 7W, 10W or 12W as specified. Battery backup upon loss of power. Available in modules of 4-ft. and longer. (Limited to 625 Lumens per foot packages).

Integral Lighting Controls

  • Various lighting controls and sensors are optional.

Corners

  • Standard 90 degree corners.
  • Custom angled corners.

Installations

  • Designed for recessed installation into drywall type ceiling systems.
  • See ceiling types section for typical installations.
  • Trimless housing requires plastering-in after installation.
  • Overlapping trim neatly closes off drywall opening.
  • For all recessed grid applications see appropriate specification sheets for those ceiling types.
  • Lengths of 12-ft. and less to use one housing with two ends pre-installed.
  • Lengths over 12-ft. will be engineered to job requirements using multiple housings with one end pre-installed at each row end.
  • Lengths over 12-ft. will include appropriate job required quick-connect plug-thru wire harnesses and housing joiners.
  • Wiring access plate provided on top. End plates have 7/8” KO.
