The Aura Lunaria Standard EM-BBU LED panel has a low profile ceiling grid with a 3 hour integrated high temperature Ni-Mh battery and wireless controller. The 3 hour battery exceeds standard requirements and the wireless controller maintenance costs and easy access. Used as lighting for standard commercial ceiling grids, The Aura Lunaria EM-BBU is typically used to replace standard 1X4, 2X2 or 2X4 fluorescent luminaires and a separate EM-BBU system.
