Exit signs are used to show occupants within a facility where they can
exit in case of a fire or other emergency.
The Prolite® range of architectural and commercial fittings include both energy saving fluorescent bulbs and led's.
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.
Light Emitting Diodes (LEDs) are very good for exit sign illumination.
LEDs are made of semiconductor materials. Light is produced when an electron within semiconductor material goes from a high-energy state to low-energy state, releasing a photon at an appropriate frequency to produce visible light.
This process of light production produces relatively low amounts of heat and most of the energy goes into producing visible light.
LED exit signs can be found with low input wattages of two watts or less, compared to up to 40 watts for an incandescent exit sign.
Although the input wattages seem rather miniscule compared to other lighting sources it is important to realize that exit signs run 24/7.
The payback with energy savings alone can be four years or less. When factoring in the additional maintenance costs associated with replacing bulbs in incandescent and fluorescent exit lights, the payback often times is less than a year.
