Further, to simplify the darkened ship installation, to provide suitable arrangement for dark adaption red lighting in Aviator's Ready Rooms, and to provide satisfactory low level illumination in the hangar space in the hangar space (SIC. I did not repeat that twice; the original report did!) in place of present unsatisfactory illumination from red bulkhead fixtures, the Bureau conducted an investigation and made trial installations of lighting fixtures and light labyrinths on the CVl6 and CV17 with the aid of the ship's and Navy Yard Boston Personnel. As a result of this study the Bureau desires the following modifications be made on the subject vessels: ENCL. 27 PAGE 1

(I haven't seen any evidence that the black on the deck surrounding lasted long) The material to be used for the construction of light labyrinth shall be of the lightest sheet steel suitable for the installation.      3.    Red Lighting for Hangar Space : Eight overhead red lights should be installed in the forward hangar section, ten in the amidship hangar section, and eight in the after hangar section. These fixtures should be installed in accordance with the arrangement as shown on enclosure (A).      (g)    Fixtures shall be type JJ-S Bureau 9-S-4853-L Alt. 5.

The JJ-S fixtures and wiring shall be installed and connected immediately and louvres applied when available.      (h)    A clear, red, steam-tight globe 9-S-2034-L Type H-1 shall be provided with each fixture.      (i)    Equip each fixture with a 50-watt inside frosted rough-service lamp, Navy type TR-12.   Encl. 27  Page 2
