The in-grade light fixtures are virtually maintenance free. They are completely sealed, drive over, slip resistant, and IP68 rated with a high temperature anti-siphon IP67 sealed cable. The integration of Bluetooth technology paired with an app allows for precise dimming and aiming, therefore, access into the light fixture is not needed and not possible. With advanced thermal management, it is predicted that the LED lamp life will exceed 100,000 hours. Access to the memorial is 24/7.
