What beam spread should I use?
For standard ceiling heights (between 2.4-2.7m), a wider beam spread of 60 degrees or more is recommended. A narrower beam spread of less than 50 degrees is recommended for ceilings higher than 2.7 meters, and more lights will be need.
What is spread lighting?
What is Beam Spread? Beam spread is the amount of space a light covers from different distances. As light moves away from a reflectorized light source, it spreads out and becomes less intense. Use this information to achieve the optimal light intensity for any task, environment or room.
How far apart are parking lot lights?
Mounting height for parking lot lights can range from 12 ft. to 20 ft. but in some cases can reach as high as 35 ft. The spacing between parking lot lights depend on the mounting height, the higher the fixture the fewer the poles needed to light an equivalent area.
What beam angle do I need?
For most domestic household ceiling fitted appliances a beam angle in the 30-40 degrees will be sufficient given the standard height of ceilings and the range, spread and number of light bulbs in the area.
What is Type 4 light distribution?
Type IV. The type IV distribution produces a semicircular light meant for mounting on the sides of buildings and walls. It’s best for illuminating the perimeter of parking areas and businesses. The intensity of the Type IV lighting has the same intensity at angles from 90 degrees to 270 degrees.
How is parking lot lighting calculated?
How Many Lights Do I Need For My Parking Lot?
- Focus On Footcandles On The Ground And Uniformity.
- Pole Height.
- 15ft: use 2-4 per pole.
- Use 150 watts for standard at 60 ft.
- Use 150 watts for bright at 40ft spacing.
- 20 ft.
- Use 300 watts for standard at 60 ft., with four each.
Can light beam spread?
How to Measure Beam Spreads. Beam spread, or beam angle, measures the spread of light (the width of the beam) from a reflectorized light source. The beam spread number is important to know when deciding how much light you want displayed on an object, a sign, or on your floors.
How do you choose an LED beam angle?
Some room shapes aren’t suitable for 60 degree beams and work better with 40 degrees or sometimes more narrow beams like 25 degrees can work well. Ultimately, your main aim in choosing the right beam angle is to get the best uniformity and to install the fewest downlights as possible.
What is a 60 degree beam angle?
The beam angle of 60 degrees is perfect for use in the living room. It is also known as floodlighting and suitable for standard ceiling heights.
What is Type 2 light distribution?
Type II. The type II distribution is used for wide walkways, on ramps and entrance roadways, as well as other long, narrow lighting. This type is meant for lighting larger areas and usually is located near the roadside. You’ll find this type of lighting mostly on smaller side streets or jogging paths.
