Incandescent:
Incandescent exit signs are inexpensive, and can use a wide variety
and number of lamps. However, incandescent lamps are very inefficient
and lose a lot of their energy to heat instead of useful light.
Standard incandescent lamps have a relatively short life, around
1,000 hours on average. Some incandescent lamps specifically designed
for exit signs have longer lamp lives up to 7,000 hours.
To increase lamp life, some facility managers install lamps rated
for higher voltage, which greatly increases lamp life but doesn’t save
energy.
Fluorescent:
Fluorescent exit lights are also inexpensive, typically using two
11- or 7-watt lamps. One lamp is illuminated until it burns out, after
which the other lamp is illuminated which saves on maintenance cost.
A fluorescent lamp has an expected life of about 10,000 hours, significantly reducing maintenance expenses.
LED (Light Emitting Diode):
LED exit signs are more expensive than incandescent and fluorescent
exit signs, but that cost gap has been closing quickly. LEDs are the
most efficient powered exit signs on the market.
LED exit lights are typically designed with strips of LEDs where the
light is reflected out of the face of the exit sign or the LEDs can be
placed directly behind the face of the exit sign for illumination.
Each
exit route must be adequately lighted so that an
employee with normal vision can see along the exit
route. 1910.37(b)(1)
Each exit must be clearly visible and marked by
a sign reading "Exit." 1910.37(b)(2)
Each exit route door must be free of decorations
or signs that obscure the visibility of the exit
route door. 1910.37(b)(3)
If the direction of travel to the exit or exit discharge
is not immediately apparent, signs must be posted
along the exit access indicating the direction of
travel to the nearest exit and exit discharge. Additionally,
the line-of-sight to an exit sign must clearly be
visible at all times. 1910.37(b)(4)
Each doorway or passage along an exit access that
could be mistaken for an exit (such as a closet)
must be marked "Not an Exit" or similar
designation, or be identified by a sign indicating
its actual use. 1910.37(b)(5)
Each exit sign must be illuminated to a surface
value of at least five foot-candles (54 lux) by
a reliable light source and be distinctive in color.
Self-luminous or electroluminescent signs that have
a minimum luminance surface value of at least .06
footlamberts (0.21 cd/m2) are permitted. 1910.37(b)(6)
Each exit sign must have the word "Exit"
in plainly legible letters not less than six inches
(15.2 cm) high, with the principal strokes of the
letters in the word "Exit" not less than
three-fourths of an inch (1.9 cm) wide. 1910.37(b)(7)
