APPLICATIONS TO SUBMARINES

eral illumination of the compartment need 

 not be more than 5 to 8 f.c. The gages and 

 any other working surfaces should be illu- 

 minated by additional directional light so 

 arranged as to avoid glare. There should 

 be not less than 20-30 f.c. of light on any 

 working surface where visual discrimination 

 is required. As noted above, dial faces 

 should be white and instrument panels light 

 (probably gray). See ''General Considera- 

 tions" above for color and brightness of 

 paint. 



Control Room 



Suggestions for maneuvering room apply 

 here. 



Wardroom 



The situation is a Httle difficult here, since 

 the ceiling is low and general illumination of 

 a fair degree of brightness is needed. There 

 should be 20 to 30 f.c. at the table surface. 

 Fixtures should be devised that have low 

 surface brightness, that spread some light 

 sidewise, and that yield adequate direct light 

 to the table surface. Quality of the light 

 should be such that the human complexion 

 is seen in its natural color. The paint should 

 be cheerful and warm tinted, with some hue 

 contrast to make the room a pleasing envi- 

 ronment. 



Crew's Mess 



There should be a fairly bright hght at the 

 table top, since the men read as well as eat 

 here. The surface of the fixture yielding 

 general illumination should be of low bright- 

 ness and the quality of the light should be 

 such that food and human complexions look 

 normal in color. Supplementary lighting 

 may be needed to provide the desired 20 to 

 25 f.c. on the table top. In this room, also, 

 the paint should be light tints that appear 

 warm with some contrast in hue from area 

 to area. 



Radio Room 



The general illumination should be well 

 diffused and of perhaps 8 or 10 f.c. There 



should be local directional lighting of 30 to 

 35 f.c. at the typewriter. Pleasing colors 

 should be used on the little space available. 



Bunk Room 



Considerable effort should be exerted to 

 made this a more pleasing living space. 

 There should be well-diffused general illu- 

 mination from fixtures that do not provide 

 glare spots. In addition, there should be 

 individual bunk light fixtures that are 

 shielded (from vision of others) and with di- 

 rectional adjustment. Possibly it would not 

 be feasible to have more than 10 to 15 f.c. of 

 light at the reading surface. This will be 

 adequate for reading the type in books and 

 magazines. Pleasing combinations of pastel 

 colors should be used for painting. 



Skipper's Cabin 



Only directional lights should be em- 

 ployed, yielding an illumination of 25 f.c. at 

 the desk and about 15 f.c. from reading lamp 

 at the bunk. The latter fixture should be 

 an adjustable directional light. Paint 

 should be in warm appearing tints. 



Engine Room 



This room permits adequate fixtures for 

 well-diffused general illumination. Surface 

 brightness of these fixtures must be kept low. 

 General illumination should be about 15 f.c. 

 In addition, there should be local directional 

 lighting where the more exacting visual dis- 

 criminations must be made, i.e., dial faces, 

 etc. Painting should be pleasing and light 

 enough for adequate reflecting surfaces (see 

 above). 



Torpedo Rooms 



Fixtures of low surface brightness should 

 be used for general diffused illumination of 

 around 10 to 15 f.c. In addition, there 

 should be local directional light where finer 

 visual discrimination is required. Paint 

 should furnish good reflecting surfaces. Use 

 some color for pleasing contrasts.
