| 4. | Hardware for recessed fluorescent fixtures: |
| a. | Where the suspended ceiling system is supported at the four corners of the fixture opening, hardware devices shall clamp the fixture to the ceiling system structural members, or plaster frame at not less than four points in such a manner as to resist spreading of the support members and safely lock the fixture into the ceiling system. |
| b. | Where the suspended ceiling system is not supported at the four corners of the fixture opening, hardware devices shall independently support the fixture from the building structure at four points. |
| 5. | Hardware for surface mounting fluorescent fixtures to suspended ceilings: |
| a. | In addition to being secured to any required outlet box, fixtures shall be bolted to a grid ceiling system at four points spaced near the corners of each fixture. The bolts shall be not less than 6 mm (1/4 inch) secured to channel members attached to and spanning the tops of the ceiling structural grid members.

The screw (size No. 10 minimum) or approved hardware shall pass through the ceiling member (Tbar, channel or spline), or it may extend over the inside of the flange of the channel (or spline) that faces away from the fixture, in a manner that prevents any fixture movement. |
| c. | In addition to the above, the following is required for fixtures exceeding 9 kg (20 pounds) in weight. |
| 1) | Where fixtures mounted in ASTM Standard C635 "Intermediate Duty" and "Heavy Duty" ceilings and weigh between 9 kg and 25 kg (20 pounds and 56 pounds), provide two 12 gauge safety hangers hung slack between diagonal corners of the fixture and the building structure. |
| 2) | Where fixtures weigh over 25 kg (56 pounds), they shall be independently supported from the building structure by approved hangers. Twoway angular bracing of hangers shall be provided to prevent lateral motion. |
| d. | Where ceiling cross runners are installed for support of lighting fixtures, they must have a carrying capacity equal to that of the main ceiling runners and be rigidly secured to the main runners. |
| 7. | Surface mounted lighting fixtures: |
| a. | Fixtures shall be bolted against the ceiling independent of the outlet box at four points spaced near the corners of each unit. The bolts (or studclips) shall be minimum 6 mm (1/4 inch) bolt, secured to main ceiling runners and/or secured to cross runners. Nonturning studs may be attached to the main ceiling runners and cross runners with special nonfriction clip devices designed for the purpose, provided they bolt through the runner, or are also secured to the building structure by 12 gauge safety hangers. Studs or bolts securing fixtures weighing in excess of 25 kg (56 pounds) shall be supported directly from the building structure. |
| b. | Where ceiling cross runners are installed for support of lighting fixtures, they must have a carrying capacity equal to that of the main ceiling runners and be rigidly secured to the main runners. |
| c. | Fixtures less than 6.8 kg (15 pounds) in weight and occupying less than 3715 sq cm (two square feet) of ceiling area may, when designed for the purpose, be supported directly from the outlet box when all the following conditions are met. |
| 1) | Screws attaching the fixture to the outlet box pass through round holes (not keyhole slots) in the fixture body. |
| 2) | The outlet box is attached to a main ceiling runner (or cross runner) with approved hardware. |
| 3) | The outlet box is supported vertically from the building structure. |
| d. | Fixtures mounted in open construction shall be secured directly to the building structure with approved bolting and clamping devices. |
| 8. | Single or double pendantmounted lighting fixtures: |
| a. | Each stem shall be supported by an approved outlet box mounted swivel joint and canopy which holds the stem captive and provides spring load (or approved equivalent) dampening of fixture oscillations. Outlet box shall be supported vertically from the building structure. |
| 9. | Outlet boxes for support of lighting fixtures (where permitted) shall be secured directly to the building structure with approved devices or supported vertically in a hung ceiling from the building structure with a nine gauge wire hanger, and be secured by an approved device to a main ceiling runner or cross runner to prevent any horizontal movement relative to the ceiling. |
| E. | Furnish and install the new lamps as specified for all lighting fixtures installed under this project, and for all existing lighting fixtures reused under this project. |
| F. | The electrical and ceiling trades shall coordinate to ascertain that approved lighting fixtures are furnished in the proper sizes and installed with the proper devices (hangers, clips, trim frames, flanges, etc.), to match the ceiling system being installed. |
| G. | Bond lighting fixtures to the grounding system as specified in Section 26 05 26, GROUNDING AND BONDING FOR ELECTRICAL SYSTEMS. |
| H. | At completion of project, replace all defective components of the lighting fixtures at no cost to the Government. |
| I. | Dispose of lamps per requirements of Section 01 74 19, CONSTRUCTION WASTE MANAGEMENT, and Section 02 41 00, DEMOLITION. |
3.2 Acceptance Checks and Tests
| A. | Perform the following: |
| 1. | Visual Inspection: |
| a. | Verify proper operation by operating the lighting controls. |
| b. | Visually inspect for damage to fixtures, lenses, reflectors, diffusers, and louvers. Clean fixtures, lenses, reflectors, diffusers, and louvers that have accumulated dust, dirt, or fingerprints during construction. |
| 2. | Electrical tests: |
| a. | Exercise dimming components of the lighting fixtures over full range of dimming capability by operating the control devices(s) in the presence of the COR Observe for visually detectable flicker over full dimming range, and replace defective components at no cost to the Government. |
| b. | Burn-in all lamps that require specific aging period to operate properly, prior to occupancy by Government. Burn-in period to be 40 hours minimum, unless specifically recommended otherwise by the lamp manufacturer. Burn-in dimmed fluorescent and compact fluorescent lamps for at least 100 hours at full voltage, unless specifically recommended otherwise by the lamp manufacturer. Replace any lamps and ballasts which fail during burn-in. |
3.3 Follow-Up Verification
A. Upon completion of acceptance checks and tests, the Contractor shall show by demonstration in service that the lighting systems are in good operating condition and properly performing the intended function.
