Preface

The following information has been prepared in order to familiarize you with the characteristics and terminology of the lighting products that are manufactured by Ashley Lighting. It is our hope that you will find this material to be informative, educational, and that it will greatly assist you in your efforts to specify and purchase lighting products.

U.L. Listing

Underwriters Laboratories (U.L.) is the worlds most recognized and trusted source for product compliance. Electrical products that bear the U.L. mark have been subjected to a series of tests and procedures that make them safe to use for the consumer. U.L. provides two separate and distinct listings for electric lighting mechanisms. These two listings are PORTABLE and DIRECT. Each of these two categories have their own identifiable labels that must be placed on the products and in an area that may be observed without requiring disassembly.

The defining difference between a PORTABLE and DIRECT fixture is that a portable lamp possesses a power cord with a plug for electrical connection. The cord of a DIRECT fixture does not have a plug and is directly wired to a junction box or outlet. For this reason, these fixtures are often referred to as "direct wired". Wall mounted lamps that have power supply cords with plugs are often a source of confusion regarding the U.L. listing. U.L. recognizes this as a PORTABLE fixture, even though it attaches to a wall. Ashley Lighting has been certified by U.L. to produce both PORTABLE and DIRECT lighting fixtures.

U.L. listing is typically required for all major Hospitality brands. In addition to this, state and local electrical codes typically require this listing before allowing a certificate of occupancy for the property. It is important to note here that on rare occasions, local codes are contradictory to U.L. codes. It is the responsibility of the General Contractor to know if U.L. listing is acceptable for the local codes. The U.L. label, which is attached to each U.L listed product, identifies the fixture as either PORTABLE or DIRECT. In addition to this, it also contains an identification number for the manufacturer of the fixture. You can determine the manufacturer of the product by visiting the Underwriters Laboratories website http://www.ul.com.

In order to be certified as a manufacturer of U.L listed and recognized fixtures, a manufacturer must commit to the following standards:
  • Use only electrical components that are U.L. listed and labeled
  • Perform a series of electrical tests on each manufactured product that ensure that there are no breaks in the electrical components or connections. These tests are performed with exceedingly high voltage that enable the manufacturer to detect potentially unsafe products.
  • Submit to unannounced sight inspections by field representatives of U.L. These field inspectors will check both finished goods and works in progress for U.L. compliance

  • Submit all new products to U.L. for compliance testing
ALL ASHLEY LIGHTING PRODUCTS ARE U.L. LISTED AND LABELED ACCORDINGLY

Table and Floors- Key Assembly Features

  1. Base
    • The Base is the terminating point for the threaded metal tube (pipe) that extends from the socket to the base weight. It allows for the lamp to be tightened securely by adjusting the locknuts against the inside surface of the base weight.
    • It also serves as a decorative concealment for the base weight.
    • Table lamps are often used to house data and/or electrical outlets for electronics usage, such as a laptop computer, these features are usually put into the base.
  2. Base Weights
    • Base weights are provided on all floor and table lamps in order to provide stability.
    • U.L regulations require that floor and table lamps be stable enough to be placed on an eight degree incline without "tipping" over. This is referred to as a "Tip Test".
    • All Ashley Lighting floor lamps are provided with ten pound molded plastic weights. These weights have an advantage over the other materials in that they will not rust on the surface on which they are placed.
    • Table lamp base weight requirement is dependant upon the design of the lamp. Base weights range from 1 to 5 lbs. Most frequently, a two pound base weight will be sufficient to comply with the U.L. standard.
    • All Ashley Lighting floor and table lamps comply with the U.L. regulations for tipping.
  3. Bushing
    • All cord holes have a bushing which serves as protection for the cord by preventing the sharp edges of a material, such as a metal base or pipe, from piercing the insulation of the cord. Bushings are a U.L. Requirement
  4. Column or Lamp Body
    • The column serves as a decorative concealment for the threaded metal tube (pipe) that extends from the socket to the base weight. It also provides support to allow the lamp to be tightened securely.
  5. Center Pipe
    • The pipe is a steel tube that is threaded on each end. This pipe is used to secure the socket, on one end of the lamp, to the base weight on the other end of the lamp.
    • Industry standard pipe measures .375" O.D. Ashley Lighting uses a .500" O.D. pipe on all floor lamps. This increased diameter provides for a more stable unit.
  6. Tray Option
    • A floor lamp tray is an optional feature that may be supplied in glass, wood, laminated wood or metal. These trays can be specified in various sizes and shapes as well.
    • An Ashley Lighting standard tray is 16" diameter x 3/8" thickness tempered glass
Wall Mounted Lamps- Key Assembly Features

  1. Back Plate
    • The back plate, of a wall mounted fixture , is the decorative cover that serves to connect the functional arm of the fixture to the wall.
    • The back plate will typically contain the switch that is used to operate the socket of the fixture.
    • It may also contain other functional items such as electrical or data outlets
  2. Mounting Plate
    • The mounting plate is the removable portion of a back plate assembly that is attached to the wall.
    • The back plate is then attached to the mounting plate.
    • These mounting plates are typically constructed of galvanized steel and are attached to the wall by means of screws or hollow wall anchors.
    • Ashley Lighting mounting plates are manufactured from twenty gauge galvanized steel.
  3. Arm Assembly
    • The arm is the portion of a wall mounted fixture that is constructed of several decorative elements, as well as the functional socket.
    • There is typically a horizontal attachment that connects the back plate to the vertical portion of the arm assembly. This attachment may be stationary or moveable.
    • The arm assembly may constructed of a wide assortment of materials as well as offered in a variety of finishes.
  4. Cord Cover
    • Portable (Fixtures with a cord and plug connection to a wall outlet) wall mounted lighting fixtures typically have a decorative cover that is supplied to conceal the cord ,from the point that it exits the back plate, to below the furniture, over which it is mounted.
    • The most common cord cover length is 24", but they can be produced in lengths up to 48".
    • Cord covers may be plated, painted, or powder coated.

CARE AND CLEANING INSTRUCTIONS:

 All Ashley Lighting products are manufactured and finished to meet Hospitality standards. All finishes are completed by the application of a final protective coating. For this reason, all products should be cleaned with a soft cloth that is dry and free of any cleaning solutions. Many cleaning solutions will cause the removal of this protective coating, thereby exposing the surface of the lamp to abrasion and corrosion. If additional information is required, please contact the factory at 870-483-6181
