Installation cost is a one-time expense that, depending on the number of units involved, could be an important consideration. In terms of purchase cost, incandescent signage—the oldest and least energy efficient signage on the market—is by far the least expensive. According to research, an incandescent exit sign costs an average of $25, a LED sign costs an average of $57, a compact fluorescent sign costs an average of $60, a photoluminescent sign costs an average of $96, and a tritium sign costs an average of $100. If your building needs a large number of exit signs, their unit cost could be an important consideration. Below, we look at how they compare to electrical exit signs—and also to each other—in terms of cost. Today, two types of non-electric safety signs are sought for their cost effectiveness: Tritium exit signs, which are powered by radioactive capsules and photoluminescent exit signs, which are powered by photoluminescence.
For example, implementing non-electric exit signage can reduce and eliminate certain expenses. For many companies, self illuminating building equipment is a viable cost saving option.
