Today, most commercial buildings contain the oldest and most expensive type of exit signage: incandescent signage, which uses 40 Watts of electricity per sign over a ten-year period for a power cost of $350. Add in lamp cost, battery cost, and installment labor, and the price to operate one incandescent sign for a decade grows to $1,465. If your building only requires a few signs, keeping its old signs won’t make much of an impact. But for facilities that require numerous signs, using energy efficient signage could make a big difference.
Luminescent Exit Signage Offers the Most Cost Savings
To cut down on the cost and carbon pollution cause by incandescent signage, energy efficiency providers often recommend compact fluorescent or LED signage, which cost $894 per sign over a ten-year period and $370 over the same period, respectively. But compact fluorescent and LED signs are NOT as eco friendly and affordable as luminescent, or photoluminescent signs, which use no electricity, require no maintenance, and are 100 percent recyclable.
Non-electrical Tritium signs that are powered by radioactive capsules are also less expensive than incandescent, compact fluorescent, and LED signage. But the $75 disposal fee required for each sign (which is only waived if you buy another Tritium sign) still makes a luminescent sign the least expensive and most eco friendly sign on the market. As an example of how much you could save by implementing luminescent exit signage, energy efficiency research shows that companies who replace 100 incandescent signs with luminescent signage can save roughly $3,700 a year in energy cost alone.
