Self Luminous Exit Signs in Damp Locations

Most indoor locations and businesses have a temperature-and-moisture controlled environment. In these spaces, it is more than okay to install cheaper electrical LED exit signs, since their unprotected electronics will not be adversely affected by rain, humidity or cold weather.

However, some indoor locations can still be considered damp locations, and you will want to identify these spaces prior to ordering your exit signs. You can go with expensive damp location electric signs, or just buy a self luminous exit sign and save hundreds of dollars!

Ideal Locations for Self Luminous Exit Signs

The following are just some of the damp locations (inside and outside of a building) where you might consider a self luminous solution:

  • Hotel or public pool areas
  • Exterior exits, underneath a protective awning or canopy
  • Car wash spray-down areas
  • Inside spaces that have fire suppression sprinklers installed
  • Above interior exits often exposed to inclement weather from the outside. These could be high-traffic egress doors, such as ground-floor lobby entrances.
  • Kitchens, food prep and sculleries
  • Parking garages 
  • Industrial warehouses and plants

Damp locations are considered to be areas exposed to clouds of water vapor and high-humidity at irregular or regular intervals. SL signs are an especially helpful fixture in kitchens, where humidity and grease vapors will quickly degrade cheaper LED exit signs made of flimsy thermoplastic. 

Advantages of a Tritium Exit Sign

Self powered exit signs do not use any electricity or batteries to operate. Instead they use a hydrogen gas called tritium, which glows naturally and provides enough visibility to be seen from 100 feet away.

Because there is no electricity, SL signs do not require all the protective capabilities that damp location signs require to protect their circuitry. The same tritium exit sign can be used both indoors and outdoors at no extra cost to you.

The tritium gas is safely sealed in glass tubes mounted inside a shock resistant housing. The housing is built to meet UL and ANSI guidelines. Depending on the model you purchase, your self powered sign will provide between 10 and 20 years of maintenance-free operation.
