7. Reflector

7.1 The reflector shall be constructed from aluminum and have a specular fi nish of the Alglas or Alzak* process, or District approved equivalent. (*Alzak fi nish a process of ALCOA). The refl ector shall be designed to provide IES Type III medium cutoff photometric pattern with adjustable lamp socket.

7.2 The reflector shall be secured to the fi xture housing so that it will not shift position or become loose when the fixture is opened or during shipping.

7.3 The reflector and lens shall be gasketed to provide a seal between the refl ector and lens. The gasket shall be made to prevent a joint gap over time.

8. Lens

8.1 The glass lens shall be made of fl at heat tempered glass for maximum resistance to thermal shock and impact.

8.2 The lens shall be secured to the lower housing by one or more movable support(s) so that it remains securely in place with the door open or closed and may be removed from the door while the door is open. The lens shall be removable without tools or with a blade-type screwdriver.

8.3 The lens shall fi t properly in the door so that any shifting of the lens will not allow the lens to fall out or allow bugs to enter the area between the lens and the refl ector.

8.4 The lens shall not fi t so tightly against the refl ector gasket that will allow the lens to break from the expansion and contraction from the heat generated by the luminaire.

8.5 Flat heat tempered glass replacement lenses shall be available for separate purchase from the manufacturer for a nominal fee.

9. Terminal Board
