What beam Angle is best for your outdoor space?
Getting perfect lighting in parking lots, sidewalks, around buildings, or other areas of commercial property has a lot to do with the way the light is directed. This largely depends on the beam Angle of your lamp. But what are the different types and which ones are best for your outdoor space? Let's take a look...

What is beam Angle?
The beam is shaped like a cone, narrowest at the source and wider as it travels outward. These 'light cones' come in a variety of widths, from very narrow to very wide, and we describe this range with the term 'beam Angle.' Simply put, the beam Angle is a measure of the degree of Angle of the cone.
Standard outdoor lighting beam Angle options:
When discussing shoebox fixtures such as parking lot lights and street lights, the most common beam angles are type III, type IV, and type V. While most of our outdoor area lighting comes standard with a Type III beam Angle, we can also offer Type IV and V distribution options to ensure the best configuration for your outdoor space.
Type III beam
The lateral width of the Type III light distribution is preferably 40 degrees. They work best when the area width does not exceed 2.75 times the installation height.
- The most versatile beam Angle type
- Cast light forwards and laterally
- Suitable for peripheral lighting
- Suitable for back-to-back installation of the inner rod
IV beam
The transverse width of the Type IV distribution is preferably 60 degrees. This distribution is generally used on wide roads whose width does not exceed 3.7 times the installation height.
- Semi-circle to provide leading lighting
- All angles from 90° to 270° have the same intensity
- Produces minimal backlight
- Ideal for peripheral installation
V-beam
The V-shaped distribution has the symmetry of the candle power and is basically the same in all side angles. It is ideal for areas where evenly distributed light is necessary, such as large commercial parking lots.
- Create a square umbrella of light
- Equal strength at all angles
- Ideal inner (not outer) pole position
