Electrical exit signs feature battery backup systems which will power the exit sign for 90 minutes during an electrical power outage. But the cost of hiring an electrician to install a hardwired exit sign can be expensive, so a battery powered exit sign sounds like your best solution. Right?
Unfortunately, battery operated exit signs DO NOT exist because such a cell would need to operate consistently for years or require constant maintenance to recharge it.
However there are two types of non-electrical exit signs that work just as well as their battery powered cousins: photo luminescent and self-luminous.
Photoluminescent exit signs glow in the dark, absorbing light during daylight hours. They are great for indoor spaces that stay lit when the facility is occupied. Photoluminescent exit signs last for up to 25 years.
When light is not available or the signs placement is outdoors, choose a self-luminous exit sign. These glow from a hydrogen gas called tritium and will stay lit for 20 years. Self-luminous signs work in all types of environments, including wet and below-freezing conditions.
Though battery operated exit signs may not exist, these non-electrical alternatives will do the job just fine. Best of all, photoluminescent and self-luminous exit signs require no maintenance during their operational lifespan.
People looking to buy exit signs usually go online to get the best price and widest selection. However when they see the word 'battery operated exit sign' they can be misled to thinking the units require no external power feed if they are not careful.
All LED exit signs are powered by electricity and feature a battery backup that provides 90 minutes of emergency power in case of power failure. The batteries are then re-charged when the building's power comes back online.
Now that we are clear why battery powered exit signs do not exist, let's look at the price for our two non-electrical units. The photoluminescent exit sign begins at less than $70 while self-luminous signs begin at less than $140. These prices are far lower than the electrically powered LED exit signs which require an electrician to install. Both self-luminous and photoluminescent signs are easy to install yourself and can save a ton of money.
After your exit sign is installed there will be no more costs for the next 20-25 years! Non-electrical exit signs are clearly the most cost-effective design on the market, at least until they make self-powering battery cells.
