Apollo CM interior lights
« on: 07/01/2013 07:39 PM »
I was wondering if anyone knows whether the Apollo Command Module had any interior lights, and if so, what kind of lights they were.

We're currently making an ultra-realistic apollo missions simulator and we want to get the color and tone of the lighting inside the CM just right as it will be one of the focus points of the gameplay. From the films and video footage it's not immediately apparent whether there were any sources of light other than from outside and from the indicators.

Would anyone have any idea about this?

There were many lights.  The Apollo Operations Handbook provides the detail on the locations of the floodlights.

Besides interior flood lights, Apollo spacecraft used back-lit electroluminescent panel lighting. The lettering itself glowed. This was promoted by astronaut Pete Conrad when working on the LM at Grumman, and was later adopted in the Block II Command Module.

If you want true realism, you'll need to have this or a reasonable facsimile.

This is the LM panel, but the CM looked similar. However CM interior lighting was fluorescent, whereas the LM was incandescent. I don't know the color temperature: http://www.ibiblio.org/apollo/Documents/LM-Panel-Sept1968.jpg

My memory is that the climax of the movie Apollo 13 also includes several closeup shots of the lights coming on as the CM was powered up; in addition to the more general shots seen throughout the rest of the movie.

Due to the nature of Hollywood, I'm sure they took some liberties with the design, but it may be close enough for your purposes.

In the movie, likely they were also liberal with the number of lights that were switched on.
 I would expect that minimum number of lights were switched on to conserve power.

Thanks for the suggestions, much appreciated.

The manual can tell me where the lights are, but I'd really like to find out how the light appeared, eg, its tint. I didn't want to rely too much on the movie but I guess it'll have to do.
