Noxion LED Bulkheads are suitable for lighting general areas like stairways and hallways. They're also suitable for outdoor use and most have a high level of resistance to vandalism too. Ones with emergency lighting units remain on even if the power fails. Noxion LED Bulkheads are extremely energy-efficient and have a long lifespan. Choosing a model with a sensor means it will only come on when it's needed saving you even more money in energy costs.
