Combined Light Intensity

Quick Selection Chart (100W, 120W, 150W & 200W)

4 factors affecting the light intensity

1. Power - the luminaire wattage
2. Height – the distance from ground to luminaire
3. Spacing – the distance the luminaires are set apart
4. Beam Angle – the use of optical lens to direct the lighting
For a more accurate LED lighting design to suit your specific workspace, please contact us for a Dialux program generated Light Intensity Iso Lines diagram.

Average Combined Lux Level

If you are installing lightings to your new industrial building or want to revamp the existing lightings, you should consider the nature of work that may be performed below them.This is because different nature of work requires different light intensity. Please see our Recommended Lux by Application Chart on the next page for establishing a suitable lux level for your workspace.

Once the lux level is established, the quick selection chart below offers you an idea as to what size of high bay lights is needed. You can reselect a lower or higher wattage luminaire if the building conditions allow you to adjust the Height, Spacing or Beam Angle.

1. The average combined lux levels given above are generated by the Dialux computer
program based on a workspace measuring 24m x36m. Values apply to workplane @ 0.8 m
above ground.
2. The luminaires used for this study is our LumiSun1 Series.
