How to Choose Suitable NEMA distribution for LED Outdoor lighting?
Choosing the right NEMA distribution for your outdoor lights is like picking the perfect pair of shoes: you want something that’s both stylish and practical.
Finding the Right NEMA distribution for Your Outdoor Needs
NEMA (National Electrical Manufacturers Association) distribution refers to the standard classifications of light distribution patterns for outdoor lighting fixtures, including road lighting, flood lights and stadium lights. These classifications help determine how light is distributed in a given area, which is crucial for ensuring adequate illumination and minimizing light pollution.
What is NEMA distribution?
The beam spread of a light tells you how wide the beam is. This is important to know if you want to light up a small sign or a big area. Check out our beam spread chart below to see how far the light will reach depending on the angle.
beam spread chart
Beam Spread (°) | NEMA Type | Description | Projection Distance |
10° to 18° | 1 | Very narrow beam, typically used for focused lighting applications. | 240′ and greater |
18° to 29° | 2 | Narrow beam, providing a slightly wider spread than NEMA 1. | 200‘ to 240′ |
29° to 46° | 3 | Medium beam, suitable for general area lighting. | 175′ to 200′ |
46° to 70° | 4 | Wide beam, designed for larger areas where more coverage is needed. | 145′ to 175′ |
70° to 100° | 5 | Very wide beam, used for extensive coverage, such as in parking lots or sports fields. | 105′ to 145′ |
100° to 130° | 6 | Asymmetrical distribution, often used for roadway lighting. | 80′ to 105′ |
130° and up | 7 | Designed for specific applications, such as illuminating walls or facades. | under 80′ |
