LED Exit Signs

  rev. 2008-12-07        

Existing Conditions

Exit signs are illuminated constantly.  Even though the load is small, the annual consumption of each fixture is significant.  For example, a 12 watt exit sign will consume over 100 kWh annually.

Retrofit Conditions

It is recommended that LED (light emitting diode) exit signs be installed to reduce energy consumption, to extend the life cycle of the fixture, and to reduce maintenance costs.  It may be possible to replace the light bulb within the fixture, which will reduce material and labour costs.

Application Details


Issues and Concerns

This measure may not be appropriate for some Exit signs.  Consult with a supplier to ensure the appropriate approach is applied to your building.






One exit sign with two 6 watt incandescent bulbs operating 24/7/52 consumes:

2 x 6 x 8760 ÷ 1000 = 105.12 kWh/year

New LED fixtures can use 750 mW.

0.75 x 8760 ÷ 1000 = 6.57 kWh/year
