PART 2 PRODUCTS
2.1 LIGHTING FIXTURES
| A. | Shall be in accordance with NFPA, UL, as shown on drawings, and as specified. |
| B. | Sheet Metal: |
| 1. | Shall be formed to prevent warping and sagging. Housing, trim and lens frame shall be true, straight (unless intentionally curved), and parallel to each other as designed. |
| 2. | Wireways and fittings shall be free of burrs and sharp edges, and shall accommodate internal and branch circuit wiring without damage to the wiring. |
| 3. | When installed, any exposed fixture housing surface, trim frame, door frame, and lens frame shall be free of light leaks. |
| 4. | Hinged door frames shall operate smoothly without binding. Latches shall function easily by finger action without the use of tools. |
| C. | Ballasts and lamps shall be serviceable while the fixture is in its normally installed position. Ballasts shall not be mounted to removable reflectors or wireway covers unless so specified. |
| D. | Recessed fixtures mounted in an insulated ceiling shall be listed for use in insulated ceilings. |
| E. | Mechanical Safety: Lighting fixture closures (lens doors, trim frame, hinged housings, etc.) shall be retained in a secure manner by captive screws, chains, aircraft cable, captive hinges, or fasteners such that they cannot be accidentally dislodged during normal operation or routine maintenance. |
| E. | Metal Finishes: |
| 1. | The manufacturer shall apply standard finish (unless otherwise specified) over a corrosion-resistant primer, after cleaning to free the metal surfaces of rust, grease, dirt and other deposits. Edges of pre-finished sheet metal exposed during forming, stamping or shearing processes shall be finished in a similar corrosion resistant manner to match the adjacent surface(s). Fixture finish shall be free of stains or evidence of rusting, blistering, or flaking, and shall be applied after fabrication. |
| 2. | Interior light reflecting finishes shall be white with not less than 85 percent reflectance’s, except where otherwise shown on the drawing. |
| F. | Lighting fixtures shall have a specific means for grounding metallic wireways and housings to an equipment grounding conductor. |

| 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. | 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. |
