Additionally, lighting should illuminate the diners softly and provide
adequate modeling of their faces.
Direct Glare: Avoid excessive luminaire brightness in dining rooms where
people will be sitting for long periods of time.
Target Horizontal Illuminance ( 10%): 100 lux (10 fc); 500 lux (50 fc) on
The lighting system in officers' dining areas should provide a soft ambient light and a
visually comfortable environment with occasional accent lighting to add visual interest to
the space. It is important to note that accent lighting can only be effective when the
ambient light level is low enough for a contrast to be noticeable. The human eye sees
and responds to changes in brightness. A highlighted area must be between three and
five times brighter than the surroundings to be perceived as a brighter area. A high
ambient level makes accent lighting nearly impossible without using an enormous
amount of energy. Carefully choose the surfaces and architectural features that are
accented for the desired effect.
Pendants over tables add a decorative accent, but should not consume a lot of energy.
This decorative effect can be achieved with a very low wattage. Additionally, because
the pendant may be in someone's field of view, a low wattage lamp will avoid direct
glare. Dimming control provides a range of light levels and allows for multiple lighting
"scenes". Refer to UFC 4-722-01 for additional requirements.
