shop lighting plan

[Cb-man]

hey guys, thanks for all the help so far. I had a 30x48 built and finishing the inside. white metal ceiling and white painted OSB walls.

I'm going with the recommended 4ft LED's from the lighting sticky.

18ft door on the 30ft side gable end. will have a lift and infrared tube heater. because the lift edge will be almost in the middle of the shop i may put the heater to one side at a 45 degree angle depending on how close lights can be to the heater the lights inbetween the wall and heater might be mounted below the heater on the wall angled down toward the floor.

i **** with computers so here is a paint sketch of my lighting plan.
does this look ok? any input would be great or where to move them.

Mmmm may have to host on Flickr or other site. Photobucket's sucking these days.

 

[Cb-man]

Well ****.... that's no good.
Oh well.

photobucket has ruined forum pic hosting lol

 

[Cb-man]

I'm guessing you have to pay to upgrade for hosting...
Just trying to figure out the best way to arrange the lights to light up my car shop
With out buying more than I need or too little.
Plus getting around my heater and lift that the one side will be about middle of the shop

Not much to say without pics, drawings and ceiling height.

 

[Cb-man]

Ok let's try Flickr...
Here is my lighting plan.
If I could do with less please critique.
Or place them differently such as all in the same direction.
The lights between the wall and tube heater I thought about mounting to the wall at 10ft angled a bit. So as to not be blocked by the heater.

Still need ceiling height.

 

[Cb-man]

Oops sorry
Ceiling height is 12ft

 

[Platonic Solid]

30x48x12
30 fixtures (60 lamps) 5x6 layout = 75fc @ 30" workplane
35 fixtures (70 lamps) 5x7 layout = 87fc ...
40 fixtures (80 lamps) 5x8 layout = 99fc ...

 

[Cb-man]

So I will add some in between the rows for 99 fc
What do you think about mounting lights on the side wall due to the heater?

 

[Platonic Solid]

15 fixtures 3x5 layout of Aleo Slim Linear LED High Bay, 2 Foot, 95 Watt (link) = 102fc ...

Mounting fixtures to the wall is a bad plan.

Unless otherwise labelled all indoor fixtures are rated for 25°C +/-5°C (77°F +/-9°F). LED fixtures like cold temps, so the -5°C doesn't apply to them. Rather than moving the fixtures to accommodate the heater, move the heater to accommodate the fixtures.

 

[Cb-man]

If the heater is hanging 12" below the ceiling 3 ft off the wall it would probably not be a great idea to put a row of lights 2 ft off the wall right?
as it would block light from shining out into the shop.

What do you mean by 3x5 layout? I'm confused on that. space between lights?

I was figuring lights 2 feet off the wall mainly over by the lift so light would shine down towards the car. I could add less lights on the sides only where needed

 

[Platonic Solid]

I'll take another look this evening. How about posting some actual pictures of what your working with.

 

[Cb-man]

I have a 30x48x12
18ft door centered on 30ft side.
Trusses 2 ft on center.
Planning a lift 16 ft from the door. 30" away from the wall. 3 post lift over all width is 11'6"
I just got the walls studded and put outlets on the walls
I'm trying the map out where to run wire to in the ceiling for lights
Here are some shots
I could just put the outside rows two feet of the wall and the heater at 4ft
The next set of lights should give me plenty of light

Here you go:

Here's the isoplot summary pdf. (link)
I used a modified James lamp IES file to simulate the LumeGen lamp so just ignore that it states James. The wattage and lumen output is accurate.

 

[Cb-man]

Thank you for that!
So is it always best the place the lights in a straight line?
Not some one direction and others another?
I was thinking lights parallel with the lift as to shine toward under hood.
But with that many lights it probably gets that direction any way.

I guess opposing direction lights looks alittle more estheticly pleasing
Like in my sketch.
I'm guessing orientation plays a part in your calcs

May just run the straight lines for ease of installation

Thank you

With this many fixtures at 12ft ceiling height, orientation has no effect.

Well, just to be sure...

Id do every other one rotated 90 degrees.
















(i kid, i kid)

 

[Cb-man]

So with 40 fixtures and almost 100 FC about how bright is that?
I know it's probably hard to explain but just gauging incase I decide to go less

 

[Platonic Solid]

How bright is that? LOL
Brighter than an office and dimmer than a sunny day outdoors.
Bright enough not to need task lighting except for some under hood and under car tasks.
Bright enough to read instructions everywhere in the shop.
Not bright enough to work with miniature circuit board components.

At 12ft, to get 100fc I would normally aim for ~8000 lm per fixture which is high enough to get you the desired output but not so bright that you'll experience glare.

Using more 5280 lm fixtures guarantees that you won't have glare and I'm sure you'll find it to be a very comfortable environment.

Keep in mind that this is 100fc @ 30" in an empty room. Once you fill it with stuff and things get dirty, you'll easily lose 20%. To make the area under the lift as bright as possible, avoid putting anything against the wall next to the lift and keep that wall clean to maximize reflected light.

Now you need to address the heater problem. Suggest putting heater at 6ft which is as far away from the fixtures as possible with this layout. I am concerned that the heat may shorten the life of the fixtures nearby.

 

[Cb-man]

Well with the Ribs in the steel ceiling it will be easier to mount them between the ribs.
Thanks guys

 

[Cb-man]

Right?
Heater at 6 ft and it will be between a row of lights. But probably hanging 12" or more from the ceiling with the reflectors aims 45 degrees to the floor.
Not sure how far away the fixtures should be from the heater.
With 5 rows of lights there is a bit over 5ft between each row.

 

[Platonic Solid]

There's exactly 6ft between each row (center to center) and 6ft between each column as shown on the layout.
Can't help you with the heater, as I have no idea how hot it will get at any specified distance.
Suggest thoroughly reviewing the heater specifications before you do anything.
