Here are some quick rules of thumb for choosing the right brightness and spacing for your LED high bay lights:
Brightness: The brightness of the LED high bay lights depends on the height of the ceiling and the beam angle of the light. The higher the ceiling, the higher the lumen output you need. The narrower the beam angle, the more concentrated the light. Here are some examples of brightness levels for different ceiling heights and beam angles:
&#; 14,000 lumens at 120 degrees from 10 to 15 feet
&#; 21,000 lumens at 120 degrees from 14 to 20 feet
&#; 35,000 lumens at 120 degrees from 20 to 30 feet
&#; 42,000+ lumens at 30+ feet but with a 60, 90, or 120 degrees lens
Spacing: The spacing of the LED high bay lights depends on the height of the ceiling and the coverage area of the light. A general rule is to space them out at the same distance as the height of the ceiling. For example, if your ceiling is 10 feet high, space them out every 10 feet. If your ceiling is 15 feet high, space them out every 15 feet. However, this rule may vary depending on the shape and size of your space and the beam angle of your light. For example, if your ceiling is above 25 feet high, you may need to space them out closer, go brighter or use a different lens to get enough light. You can also call us for a free lighting layout l to calculate the optimal spacing for your space.

I have a 40x70 warehouse that I will be working on and detailing cars. I want to convert from old lighting to led primarily for brighter lighting and lower energy costs. The lights are currently at 17 feet above floor. I was looking at your 150 wattand you 100 watt high Bay UFO lights. Would this be appropriate? How many would I need and how far apart etc. thank you. Bob
Here is our first answer;
Thanks for reaching out. Those are awesome lights so you are on the right track. At 17 feet high you can go 100 watts or 150 with a 120 wide angle. That is the angle the light comes out at. I usually do not recommend 150 watts until we get closer to 18 feet high and up. You are right at the cut off.
1.
Do the 150watts high bay lights and use 120 wide which is standard. 14-20 feet we recommend the 150watts. At 17 feet you can go wider angle and still get good light to the ground. So the 6x3 pattern would give you good coverage. 7x3 for 21 lights for higher brightness.
If you can run additional wiring, we can also do all of this withversions so you can go a bit brighter and adjust down to save energy. You can create a few sections. Maybe dim down half of the warehouse where it's just parked cars and leave the rest full brightness. See our knowledge base and video on 0-10v dimming for more info on these.

2. Use 100 wattsand space them out every 8-14 feet (8 for high brightness, 14 for adequate). A 6x3 pattern for example is 18 lights for basic lighting, or go 7x3 (or 6x4/8x3 depending on wiring) for 21-24 lights to get a medium brightness level. 8x4 for 32 would be very high brightness. So that&#;s just an estimate. Somewhere in there.
21 of the 100 watts in dimmable high bay lights would probably be my recommendation for bright lighting. (without knowing more)
There is bulk pricing on all of this too. Choice of angle and light color. All inclusive. 5 year Warranty, full liability insurance, USA toll free support and no tax outside of CA.
Feel free to give me a call and I can answer any other questions.
Thanks

I have a 30x40 shop and need to know how to light it. The sides are 14ft and the peak is 17ft. What do I use? Jim R
Here is our 2nd answer;

Thanks for reaching out. Our standard shop lighting is always 2 rows of 2 for 4 lights. Anything from 20-40ft x 20-40ft fits right in there and gets great results. I would recommend 4 of our 150 watt UFO high bay lights. We never want to use less than 4 because we want light coming from at least 2 directions to reduce shadowing. So even on The 20x20 we go to 4, its a bit overkill with lumens but the uniformity is more important. See the image above to see what happens when one light is out, lots of heavy shadowing.

So you can see there are so many variables in lighting design that you have to think through lots of options. Number of fixtures, brightness, height, light angle, where you can actually run wiring, etc, etc. There is a whole science called photometrics that does awesome analysis on this. For larger buildings they can do a full design. On something like this it&#;s just not worth it.
This customer went with 21 of the 100 watt LED High Bay lights and emailed us later on to say that they were very pleased.
