A high mass pole is a tall, vertical structure designed to support lighting fixtures at a considerable height above the ground. These poles are commonly used for high mass lighting systems in various applications, such as illuminating large outdoor areas like highways, intersections, airports, seaports, sports stadiums, and parking lots. The primary purpose of high mass lighting is to provide uniform and extensive illumination over a wide area.

Key features of high mass poles include:

1. Height : High mass poles are significantly taller than traditional lighting poles. Heights can range from 25 to 150 feet or more, depending on the specific requirements of the lighting    application.

2. Arrangement of Luminaires :   At the top of the pole, there is typically a luminaire ring or crossarm that supports multiple lighting fixtures. The arrangement allows for optima  distribution of light across the designated area.

3. Easy Maintenance :   High mass lighting systems are designed for easy maintenance. Lowering devices or systems are often incorporated to bring the luminaires down to ground level for maintenance     without the need for specialized equipment.

4. Versatility :  High mass lighting  is versatile and can be customized based on the lighting requirements of the specific location. The number and type of luminaries, as well as their wattage can be adjusted to achieve the desired lighting levels.
