LED bulkheads, often called ceiling lights (although they're also used on walls), are suitable for lighting areas like stairways and hallways. They're also perfect for general lighting and/or emergency lighting. Fixtures that are dustproof, waterproof and resistant to vandals are an excellent choice for outdoor applications. Models that have an emergency lighting unit stay lit even in the event of a power cut. For even greater cost savings, choose a bulkhead with a sensor and the light will only turn on when it's activated. LED Bulkheads are extremely energy efficient and have a long lifespan making them the ideal replacement for conventional fixtures.
