What is a Shop Lighting Plan?

A Shop Lighting Plan is a Photometric Lighting Analysis that addresses the lighting in a specific shop or work area. Shops are typically areas with ceiling heights that are less than 20 ft high.

They are areas where work is done and performed. The work may be complex and detailed, and having a well lit area increases work quality and improves worker safety.

Using photometric software, you can model an indoor shop area layout. It allows you to define shop space, ceiling height, existing light location or ideal light location.

Lighting engineers can input shop light fixtures at specific locations, angles, orientation and height.

The software calculates light levels and provides a comprehensive visual layout report. The report displays calculation points representing the foot candle reading at defined locations.

How many lumens do you need for a shop?

The number you need depends a lot on the use and type of work being performed.

For general work, consider 20-30 foot candles

For work around machines, consider 50-75 foot candles

For fine detail work, consider 100+ foot candles

Shop Lighting Calculator

To use this calculator, enter the following:

  1. Length, Width and Height of room in feet
  2. Lumen output of the fixture you want to test
  3. The desired foot candles of the fixture

What it will return:

The approximate number of fixture you will need to get the required foot candle levels. 

Please note: this is a lighting layout approximation tool. It should never be used in place of a lighting plan or photometric design. The basic tool we provide will not visually show how good the distribution is, light placement, what optic you may have to use or the avg/min foot candle ratios.
