High Mast Lighting is used to illuminate large open areas, commonly for mines, industrial areas, highways, recreational fields, and large rural housing settlements. LED High Mast lights are an ever popular application over the energy hungry HID lights that are usually mounted in a luminaire ring on top of a >30m high mast (hence the name) or other structure but can be laid out differently depending on the required application. LED high masts are the very best solution for new installations and to replace old traditional, inefficient high mast luminaires.
High mast lighting is used to illuminate large outdoor spaces. The high mast structures are generally >30m high with high mast flood light luminaires mounted on top facing down. The lights are mounted onto a luminaire ring which typically consists of four, six, eight or twelve lights.
Common applications for high mats include highways, recreational fields, mines, industrial areas, and large rural housing settlements. The benefit with a high mast structure is that it takes up a very small area on the ground while providing excellent illumination for large outdoor areas.
Traditionally high masts use HID light sources such as high-pressure sodium and metal halide and mercury vapour. Today, more and more high masts are using LED luminaires due to their numerous benefits.
LED high mast luminaires offer excellent benefits compared to older technologies including:
The main difference between LED flood lights and LED high masts is the beam angle. Floodlights generally have a wide beam angle of 120° and are installed at a comparatively lower mounting height. High masts, on the other hand, have narrower beam angles of typically 90°, 60° or 30° due to their high mounting height. The narrow beam angle helps concentrate the light which translates into more light on the ground where it is needed.
5000K-6000K is considered the best colour temperature to maximise visibility as it closely mimics natural daylight which human vision has evolved to see best. Colour rendering (CRI) is also an important factor. A CRI of >70 is ok for general outdoor applications however a CRI>80 is better for better colour accuracy (ie. if inspecting colour coded stickers, labels or containers etc.). Traditional HID high mast luminaires such as high-pressure sodium (HPS) have a stark orange light and very poor colour rendering which makes the environment look monochromatic.
