** G. Fluorescent Fixtures: Shall be as follows:**

**  1. General: Unless otherwise specified, body, reflectors, wiring
cover, end caps, door frame, hinges and latches shall be steel, not less
than 24 ga for wiring cover and 22 ga for all other parts. Body and
reflectors shall be die formed and shall have embossed ribs or flanges
for rigidity. Doors shall seal when closed to prevent peripheral light
leaks. Steel parts shall be pretreated with a multi‑stage, phosphate (or
other similar) under‑finish to enhance paint adhesion and corrosion
resistance. Steel parts shall be finished white with a high gloss baked
enamel or baked dry polyester powder coating of 85% (minimum)
reflectance.**

** 2. Ballast: Unless otherwise specified, ballasts shall be rapid
start, high power factor, Class P with A sound rating and catalog‑listed
by the manufacturer as energy saving type.**

** 3. Type A Lighting Fixture: Shall be a 2 x 4 foot recessed troffer
with prismatic lens in steel framed door with hinges and latches. Lens
shall be 100% virgin acrylic; overall thickness not less than 120 mils;
unpenetrated thickness (thickness between the base of the prisms and the

for installation in a lay‑in, suspended ceiling. Ballast shall be
suitable for 120 V, 60 hz power supply. Fixture shall be lamped with two
energy saving (35 watt max), 3,000 lumen (minimum initial output) lamps.
**

** H. H‑I‑D Fixtures: Shall be as follows:**

**  1. Use suspension kits consisting of swivel, canopy and stem to hang
fixtures which are to be suspended in finished space.**

** 2. Where fixtures are to be stem mounted in unfinished space, use a
combination swivel box cover with threaded conduit at the upper end of a
conduit stem.**

** 3. Where chain‑suspended fluorescent fixtures are indicated, use a
box cover with chain hooks and receptacle to hang the fixture from the
outlet box. Attach the \"Y\" yoke end of the chain to the top corners at
each end of the fixture in a manner guaranteed not to come loose due to
vibration or bumping. Connect the fixture to the box cover receptacle
