Smarterlite's Eos Environmental Exit Signs are battery-free and have no electrical components, removing two primary causes of failure in Exit Signs. When Exit Sign batteries fail, the whole sign is disposed of, generating battery, circuit board and plastic waste. Less than 10% of electric-battery exit signs are recycled. By eliminating batteries and electrical components from Exit Signs, Smarterlite Eos Exit Signs have a 30+ year life when the industry norm is less than 5 years, with large buildings experiencing 20-25% failure rates per annum. Smarterlite's Eos Environmental Exit Sign consume no power on their own. In comparison, electric-battery Exit Signs typically use 5W to 10W.
