ESTONE LED is a new outdoor lighting concept that uses environmentally friendly materials like cellular concrete (ESTONE) and LED lights. ESTONE is a durable, fire resistant material that is resistant to moisture, frost and decomposition. It has high compression resistance and low water absorption. LED lights are 80% efficient, with an operational life over 50,000 hours, virtually eliminating routine bulb replacement. These LED lights provide bright white light suitable for outdoor lighting applications while consuming a fraction of the energy of incandescent bulbs.
