All Lamps

Hardwire Dimming Requirements: Technology is rapidly changing in lamping, creating some uncertainty when specifying dimming requirements. Consult with your electrical engineer on the lighting control (dimming system) that will be used before specifying dimming requirements.

Diffusers: To conceal lamping, diffuse hot spots or minimize bugs or debris, a diffuser may be added to most portable or hardwire fixtures, depending upon lamping specified.

An acrylic diffuser at the top or bottom of your fixture in gloss or frosted opal/white with a coordinating lock-up knob is available.

Perforated metal can be supplied in metallic, white, or painted to desired finish.

Specify standard wall switch (hard-wired) or switch on body or backplate:

Push thru standard, also available: on/off rotary, on/off toggle (ADA compliant), on/off push (ADA compliant), rectangle rocker, round rocker, on/off rocker in-line switch.

Wall/Sconce ADA Requirements:

Ceiling Lamps

Standard installation is hard-wired directly in an electrical junction box (j-box), please contact us for a non-traditional installation.

Specification tips for ceiling fixtures:

  • Review sprinkler head locations
  • Specify voltage requirements 120-volt or 277-volt system

Review installation requirements:

  • When specifying large chandeliers review door openings
  • Before selecting the fixture, always determine the size of the doorways that the fixture will go through and note restrictions on specs. Also note size restrictions on loading docks, freight elevators, and entry to the installation area.

Consider relamping requirements—removable bottom acrylics often allow for simple future relamping.

Mounting details:

  • Check the ceiling height of the space to determine proper mounting applications. Typically, the bottom of the fixture must yield at least 8 feet above finished floor.
  • Solid rod, stem, or cable can be specified. However, use of a solid rod or stem will make field adjustment difficult if the specified ceiling height changes during construction.
  • Cable or chain is recommended when the ceiling height is unknown

Canopy requirements:

  • Lightweight fixtures (50 lbs or less) require mounting directly to a junction box with (2) 8-32 mounting screws into finished ceiling
  • Medium-weight fixtures require a 3/8" threaded rod secured to the above existing structure and must extend 1" below finished ceiling
