Thoughts on this Lighting plan?

[Juiced06GTO]

Alright guys, this is what I have come up with so far. The idea being to have a mix between recessed and high output low bay lighting to really blow the place up with lights. The plan is to have two groups of 9 recessed cans (max wattage I can have on each dimmer), and then 6 - 15k Lumen UFO LED low bays just on a switch for when I am doing detail work and the place needs to be as bright as the sun. I am thinking the recessed will be enough for general in and out stuff or quick tasks. If all lights are on, recessed and high bays, I'd be pumping 109k lumens of light, 19k from the recessed and 90k from the low bays. Thoughts? Orange and blue dots are the two switched recessed, black are the high bays.

I based mine on I think 30+ Lumens/ft at about 3ft AFF, if memory is still working. There was a web link for laying this stuff out I found on these forums https://www.visual-3d.com/tools/interior/default.aspx?id=217794

I was looking for that and couldn't find it, thanks! I just wish I could mix fixtures on it, you can only see one fixture in place at a time.

You don't add up lumens. Do some searching here, tons of good resources.

What is your ceiling height?

It's not possible to evaluate it without dimensions, HxWxD. As Mike, said, total lumens is not a figure that's relevant, despite what all the knuckleheads on youtube say. It simply means nothing. What is important is where the light is directed, how it fills in shaded areas, is even across the work plane and puts the correct amount of light where you need it.
Are you going to have cabinets, machines, work benches, lifts in there?

Just a heads up to avoid any confusion, in the software you targeted 30 foot-candles, not 30 lumens per square foot. There's a difference between lumens per square foot and foot-candles. Lumens per square foot is not a relevant measurement. Foot-candles is what we need to know.
The software gave you 37 foot-candles, which is slightly higher than you asked it for. That's how that software works.

For arguments sake, take your "total lumens" of 32,082 (5347 x 6) and divide it by 600 (20x30) and you get 53.5 lumens per square foot. Notice how far off this is from 37 foot-candles. This is why we dont use total lumens or lumens per square foot in calculating how much light we have. They're just not relevant figures.
Hope that helps explain...

Thanks, yes I struggle with proper terminology unless I have my nose in the books trying to work it out

Dont we all....
It's confusing unless you work with it every day.

Hey guys, my building is 30x40 with 12' ceilings. There will be work benches tucked in along the walls, although I am not exactly sure where yet. I am hoping to have a mill, lathe, drill press, and metal working area in the front right corner. The left will be for ground level work or storage of vehicles. That's my preliminary plan anyhow. Thanks for the advice so far!

9 recessed cans will feel like it is candle lit
