How many and what type would be good for a 40x70 building? 10 foot ceilings with white metal on inside? I have seen some LED's that are yellow looking. Don't want those.. I want the brightest light available,,,Limited number of windows and will be used for a retail store. Also any ideas on outside LED's for parking around building,,,thanks
How many LED's??

I'm not a design engineer, but theses are going to work in my. 8' ceiling garage., mostly through experimenting fixtures and positioning.They are bright, white and illuminate a good size area, using quad fixtures. The two test fixtures are 6' apart.
I plan on using 16 tubes (4 quad fixtures) in the 19x24' two car section of my garage.
Might be overkill, but I need lots of light.

Yes....should be real good! I'm going to stay right here.....
To determine how many lights you need you have to do some simple calculations
1- Determine the area per (ft²) of the room that you want to light.
2- Determine the total wattage required for this area by Multiplying the area by 2, which is the average watt/ ft² and range between 1.5 to 3 according to the function of the room.
3- Divide the total wattage by the output wattage of the bulb that you are using or plan to use, so you get the number of lights
this will give you the exact number of the required light units, after that you have to think how to space your lights? you can check recessed lighting spacing to do that the right way.

All the incandescent lamps you ever used in residential interior lighting were 2700k. It's a nice warm cozy color for homes.

This is subjective so think 2700k as warm old school incan and 5000k current daylight LED. If all you're doing is lounging around 2700k could work. Want down lighting? Up to 4000-5000k. A play / multi use room could easily do 4000k

I have a 30' x 30' garage with 12' ceilings and mounted 9 LED shop lights (4' long each).
They are spread out in 3 rows equal distance apart.
They are all 4000k and I have excellent lighting with them.
Usually I just turn on the two outside rows and leave the middle row off, but if I am working on something (my Argo has a busted axle right now) I turn on all three so that I don't have to worry about shadows.
I also have a small portable LED work light that I can use for working underneath vehicles, etc.

I will try the 4000k bulbs, thank you
