How many LED lights do I need for my warehouse?

We have received many such questions and are happy to help. Some of them consider light colors and heights, some of which are about fixture spacing. We are happy to help. We think sharing an example can help you think about everything we do. This is a recent example;

I have a 40x70 warehouse and I will continue to work and detail the car. I want to switch from old lighting to mainly for brighter lighting and lower energy costs. The current light is 17 feet above the ground. I am looking at your 150 watt high bay lighting and 100 watt high bay lights. Is this suitable? How much do I need and how much installation space is required for each fixture. Thank you. Dick.

Here is our first answer

Dick:

Thanks for your trust, These are great, so you are on the right track. At 17 feet, we recommend using a 100 watt high bay light because the angle of the light is 120 degrees and using 150 watts will waste energy. Unless you need to install the luminaire at a height of nearly 18 feet.

So

1.Use a 100 watt high bay light to separate it every 8-14 feet (8 for high brightness and 14 for sufficient). For example, a 6x3 pattern is 18 lights for basic illumination, or 7x3 (or 6x4 / 8x3, depending on wiring) for 21-24 lights to achieve a medium brightness level. The 32x 8x4 will be very high brightness. So this is just an estimate. Somewhere there.

2. Use a 150 watt high bay light and set the width to 120 wide. At 17 feet, you get good light on the ground at a wider angle. Therefore, the same 6x3 mode will provide you with good coverage. 21 lights 7x3, higher brightness.

If you can run additional wiring, we can also do all this with a dimmable high bay light version so you can be brighter and lower to save energy. You can create several sections. Perhaps in the dim half of the warehouse, it just parks the car and keeps the rest of the full brightness.

The 21 watts in a 100 watt dimmable high bay light may be my suggestion for bright lighting.

Summary

So you can see that there are many variables in the lighting design and you have to think through a lot of options. The number of fixtures, brightness, height, ray angle, location of the actual running wiring, etc. There is a great science called a photometer that does a great job of analyzing this. For larger buildings, they can be fully designed. In such a thing, this is not worth it.

The customer purchased 21 100-watt LED High Bay lights and sent them to us later via email saying they were very happy.
