6.5.2 LIGHTING SCHEMES
At least two (2) proposed lighting schemes for special areas (Visitor
Lobbies, Cafeterias, Atriums, etc.) should be provided. Each layout
shall vary in concept and materials such as fixture layout, fixture
type, lamps, louvers, reflectors, etc. This will enable the VA to
select the best scheme to suit its goals and budget requirements.
6.6 LIGHT SOURCES
6.6.1 INCANDESCENT
Use compact fluorescent lamps in lieu of incandescent light sources,
where appropriate, for general illumination.
6.6.2 HIGH INTENSITY DISCHARGE (HID)
Utilize HID sources for large interior utility spaces having relatively
high ceilings or where maintenance is difficult (i.e., Boiler Rooms and
Mechanical Equipment Rooms.) High pressure sodium is preferable where
color is not an important factor.
6.6.3 FLUORESCENT
(a) Use fluorescent lamps as the principal interior lighting source.
(b) Utilize F32T8 32 W (watts) rapid start, fluorescent lamps with a
color temperature of 3500 degrees K, a color rendering index (CIE) not
less than 75 and an initial 3050 lm (lumen) minimum output, except
color- corrected lamps having a color rendering index (CIE) of 90 or
above and correlated color temperature between 5000 degrees K and 6000
degrees K in the following areas:
(1) Over the beds in all Intensive Care Units
(2) Over the beds in Coronary Care Units
(3) Over the beds in Recovery Rooms
(4) Over the beds in Life Support Room
(5) Over the beds in Observation and Treatment Room
(6) Electromyographic Rooms
(7) Autopsy (Necropsy) Rooms
(8) Surgery Rooms (color shall match that of the O.R. light)
(9) Dental Rooms (Examination, Oral Hygiene, Oral Surgery, Recovery,
Labs, Treatment and X-ray)
(c) In other areas where special lighting may be required, follow the
latest illumination levels list.
