Smarterlite's Apollo Environmental Exit Signs are battery-free and have no electrical components, removing two primary causes of failure in Exit Signs. Apollo Environmental Exit Signs are printed on study aluminium sheet, making them ideal for outdoors as well as indoor environments where tough impact resistant signs are required. Installations include warehouses, distribution centres, factories, back-office areas and big-box retail outlets. 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 Apollo 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 Apollo Environmental Exit Sign consume no power on their own. In comparison, electric-battery Exit Signs typically use 5W to 10W.
