spitfire557 - Low cost dimmer (link). Use standard wall switches for ON/OFF function. Dimmer connected to violet and gray wires from fixtures - jumping from one fixture to the next and ending at the dimmer. 1 dimmer can control all fixtures even if you have multiple ON/OFF zones.

Thank you! I plan on doing three zones so this is good to know. I went ahead and ordered the 90W lamps which you linked.

spitfire557 - Did you order 12 or 15 fixtures?

I ordered 8 for now, and will order another 8 in a few weeks (since they come in pairs). Gonna cost me an extra $40 for shipping but much easier hit on the bank account. Will also keep the wife at bay. LOL

I’m sure I can make use of the extra fixture I’ll have.

 

[Platonic Solid]

spitfire557 - Layout for 15 fixtures is real simple - 3x5 pattern, 10ft fixture center to fixture center in both directions. ~5ft wall to fixture center in both directions.

Okay, great. Again, thank you for your help! Not only for helping me, but everybody on this forum.

Hi, I'm brand new to this board (literally I just signed up) I'm pouring concrete tomorrow on a 26x45 and was hoping for your input on lighting placement and type. I'd prefer Led. I've enclosed a pic of the floor plan. The center bay has 12ft ceilings and will have a 2 post hoist. The ceiling heights on either side are only 8'3". I apologize in advance if you have answered this one before.

 

[spitfire557]

Lowest cost/highest lumens per dollar fixture = 16000 Lumen 120W for $60 ea (link). Qty. 12 fixtures 3x4 pattern yields 103fc @ 30" workplane. Add dimmer and zones to suit useage. Total cost = $720 + shipping.

Above fixture is higher output than recommended for 12 ft ceiling. The 90W (link) is more appropriate at Qty 15 (3x5 pattern).

Anyone ever have issues with ordering from this site? (www.ledlightingwholesaleinc.com)

I ordered on 11/13/19 and received the confirmation email, but never received a shipping email. A few days ago I sent them an email asking for an update but haven't heard back yet.

That's where I ordered mine from. Took 10 days to ship and arrived via freight 3 days later.

24 x 24 9ft 6 ceiling

Have new detached 24 x 24 with 9ft 6" ceiling height,in which I will be doing woodworking and other general tinkering.

Looking at using the maxlight 2 bulb fixtures https://www.ledlightingwholesaleinc.com/LSS2XT8USE4803-p/lss2xt8use4803.htm with the Greenlight Depot 18w versa T8 led https://greenlightdepot.com/products/4ft-18w-led-linear-versa-tube-ul-dlc?variant=3706824644 in 4 or 5k

Wondering how many I will need for effective light, work area will include the center with dedicated machines against the walls.

Using the visual interior tool http://www.visual-3d.com/tools/interior/default.aspx?id=217794 it suggests 3 rows of 5, should work well?

 

[Dh3256]

You'd rather spend $500 on 24 disposable any-brand plug-in shop lights intended for 8 ft max mounting height for 48fc @ 30" workplane than spend $1000 on correct style fixtures for 100fc?

Off on a tangent, the answer to my question may be in there ;-)

My space is a 27 x 16 garage with a sloped roof, so ceiling height is 8' to 9'. Construction is wood frame - open 2x4 walls with waferboard, ceiling is 2x12 joists with plywood above.

I do casual auto repair, woodworking, and miscellaneous home repair work in the space. I typically also use task lighting when I am working.

I have access to some 3' LED shop light type fixtures for a couple of bucks a piece, and am trying to figure out how many may be needed. The only specs I have on the fixtures are 3000 lumens and 4000K CCT.

I need to make a quick decision, limited time offer, and am trying to get some idea how many I would need. I'm thinking 30 but don't really get if that would be too many or not enough. I would appreciate your thoughts. Thanks!

Edit: looks like 100 fc is a recommended value for this kind of space, and 27*16*100/3000 = 14.4, so 20 fixtures should be enough and 30 is overkill. Does that seem right?

Dh3256 - The math doesn't work that way, but your number happens to be close. Just plugging in 27x16x8.5 into the Visual Tool (link) and changing Ceiling|Wall|Floor reflectance to 20|20|20 yields Qty.12 5347 Lumen fixtures. 12 x 5347 Lm = 64164 Lm/3000 Lm = 21 fixtures.

I am a new here and am looking for some guidance and recommendations for lighting for my new shop.

I just built a 40x80x16ft tall shop with a 14x14 service door in the front and a 10x12 service door in the back.

I am looking for good lighting options that will provide a well lit building without shadows.

My original thought was to hang 15 ( 5 rows of 3 lights) of Round 150 Watt UFO style LED high bays.

It seems that all of those I have looked at are very similar and from China. I did buy one light (from Amazon so I can return it if necessary) it was a Hyperlite Hero Series UFO light. Its 150 watt, 21000 lumens with a CRI >70

The construction quality seems decent but without a reflector attached it does produce glare if there is an upward glance towards the ceiling.

The offer a globe/reflector for the light which would fix this. However then the fixture gets pretty expensive for something made in China.

I was also looking at some 2ft Integrated LED lights by Commercial Electric @ Home Depot.

These were rated at 171 watts, 18000 lumens and a CRI of 80.

The linear LED looks like it would be a better distribution of light, but I did like the install convenience of the round LED.

If anyone has suggestions on what the best bang for the buck is, it would be appreciated.

Thanks again
Steve Lane

I wanted to finally close the loop on a project that Platonic Solid and others helped me with. I am building a 100' x 40' x 12' eave height metal building. It is insulated with R38 in the ceiling and R25 in the walls. A thick vapor barrier that is white in color then covers the insulation on both the ceiling and the walls as shown in the pictures. As you can see none of the girts or purlins are visible as this is the thickness of the insulation. I recently finished epoxy painting the floor with a very light gray color that has a light reflectance of 72%.

The lights that Platonic recommended for a desired 100 fc at 32" high were 110 watt high bay LED. The ones I ordered were very similar to these https://greenlightdepot.com/collect...-mounting-gen-5-ul-dlc?variant=16980078755883. The layout was 4 rows along the 40' dimension and 8 rows along the 100' dimension all aligned with existing roof purlins. I am extremely happy with the outcome. Granted everything is new and I haven't moved any equipment in yet, but the readings I am getting vary between 125 fc and 145 fc. This week I intend to start filling the saw cut expansion joints with Sikaflex.

Thanks again Platonic. You are a tremendous asset to this site.

steiner5 - Nice Space! Thanks for returning to post after pics. That white floor really makes a difference.

I've been too busy with work projects lately to spend much time here.

 

[spitfire557]

I’m sure I can make use of the extra fixture I’ll have.

Ended up hanging the 8 lights I ordered. I hate to admit it, but I decided to go against the advice given and tried a 2x4 (total of 8 lights) arrangement. These things are a breeze to mount/adjust so I figured I could undo it if I was displeased.

With only 8 lights hung, I was amazed at the amount of light inside of the garage. I ended up ordered 2 more lights though, to help illuminate the work bench area of the garage a bit more. Still need to finalize the wiring runs and tidy it up a bit, but I'm very happy to have a lit working space now.

 

[Platonic Solid]

spitfire557 - The suggested 3x5 arrangement will reduce the shadows between cars and walls as evident in your picture.

 

[spitfire557]

Good point. I'll have to take another look then. It would be very easy to space the two banks further apart and add a third bank so that's an option.

Sorry to both you, but I can't quite find my exact set up in this thread. I've got a 42x64 with 14' sidewalls. Two 12x12 doors on on of the 64' walls as well a walk in door on that side. I will eventually have a white metal ceiling, but it will be open for quite a while. I'm looking at the lights that spitfire used and was wondering if they would work and what type of layout I should use?

Not bad, but at 12' you'll need a fixture with ~8000 lumen output.

 

[Fisherguy]

Looks like 2 hoists? Where's your work bench(es) gonna be?
My shop is 25 x 40 and I can't figure out where to put one hoist.

 

[thoyer]

Looking at my pic, the work area would be in the upper right. I wanted to make the garage bigger, but this was the largest size I could put on my property without having to get into storm water management per local ordinances.

I wrestled with placement for a long time. Hopefully this works as the radiant floor tubing is laid out for clearance where the 2 post is going. Can't easily move it anywhere else.........

 

[thoyer]

Not bad, but at 12' you'll need a fixture with ~8000 lumen output.

So based on your recommended bulb / fixture recommendations 8k lumens is not readily achievable. So do I add another row of fixtures, or change the orientation / location and add more fixtures.

The layout I posted had 18 fixtures. If 8k would be the level that would \mean a total of 144k lumens.

The recommended fixtures / bulbs are approx 5k lumens which would mean I'd need approx 28 fixtures. Four rows of 7 fixtures?

Am I thinking correctly here?

Thanks,

Tom

 

[Toomanytools?]

Maybe something like this , I don't think you need 18, 5 rows of 3 (15).

[ED26]

Any direction you can provide for me on my garage..

dimensions are 27x20x9 ceilings framed at 24 on center

The garage has a jog on a 45 degree angle to account for wash tub and the entry man door.

Also I drew in the back work bench and side storage cabinets along the right side wall.

Thanks for any help

 

[Platonic Solid]

thoyer - Here's one option - https://www.prolighting.com/commercial-lighting/ledready/t443ssubcxx00p0-18w5k.html. I don't have much time to deal with this right now.

 

[Sleepdoc]

I have a space that is 23x20x8.3' and will be used mostly for detailing cars. The walls and ceiling are drywalled. I was thinking of using the TechBrite 48" 3 lamp 8000 luman strip lights (PN T443SSUBCXX00P0-18W5K). I was playing around with the visual interior tool and came up with 3x3 pattern. Does this seem reasonable?

 

[wardenclyffe]

21'x19.5' garage, single double width door.
10' ceilings - unfinished, straight drywall.

It's been a few years since I set up my lighting and I previously used the sylvania tool. (but cannot find the specs I used at the time)

I am wanting to do the VIT tool and then model the distribution as you have done, especially as I add in new workbenches and tools. (Dialux and then ?)

Currently I have two rows of these: 1284GRD RE (4' T8 x 4 bulbs)
Total of 6 units evenly spaced, hung ~8" or so from the ceiling. I used a mixture of the phillips alto bulbs for the high CRI and mixed the color temp between the 3000k and 5000k bulbs.

I have a workbench on the back wall with two sets of cabinets above.
I used halogen strip task light under the first cabinet above the workbench. (full 8' double fixture (2x - 4') single bulb)
I then put two 4' two bulb reflectors on top of the upper cabinet pointed at the cieling using the costco LED replacement T8 bulbs.
To the side of the garage in an additional 3' x 3' bump out for the entry to the house I hung an additional two led bulb fixture from costco.

pretty much a ton of light and I think I got over 100fc at 30" from what I previously did, but as I said, I cannot find the old plot.

Any advice/help would be greatly appreciated.

 

[rotortuner]

To make sure you have all the options, here is my preference: LED layout using the Diva Light 2ft 13,700 Lumen and 19,300 Lumen fixtures (linked). Any similar output LED fixture with a medium (spherical) distribution will work. Initial cost is a little higher, but you’ll easily make that up over time as it cuts your lighting electric bill in half and you won’t be waiting 5-10 minutes for them to warm up to full brightness like the F54T5HO fixtures. Same mounting heights as Post #382. Fewer fixtures in lean-to areas.

​

.

Going back a ways here, my original posts are back on page 20. My construction ended up taking way longer than I thought but I did use the layout platonic worked up and went with the LEDs and so glad I did. No warm up is awesome. It took 32 fixtures. These are the linear high bays from bees lighting. Took me about two weeks to install them all myself and also put in dimming. They upgraded the LEDs since the original post and they put out more lumens, that’s why I added the dimmer to cut the glare a bit. 4 switches controlling 4 banks of lights. One bank each outboard that has the 10 each 110 waters and the center bay is cut in half 6 165 waters per switch. Used mwbc to cut the amount of wiring I had to run which really helped. All in 12ga. 18/2 t stat wire for dimming and it’s set up to dim 3 zones. The center and each outboard lean to. I bout cheap 1ft extension cords off amazon and cut off the female end. That was to cord all the lights and plug into outlets above the lights. They were only $1.50 a fixture to cord which is pretty cheap in my book. Very happy with it. It’s bright and seams well distributed all the way to the edges. Thanks again!

I would recommend the linear high bays. Built well. I had one drop 20ft onto concrete and still works with minimal damage. I ordered a couple to compare off amazon and they all seam pretty couch the same but bees seamed just a tad nicer. They shipped pretty quick and showed up on a pallet. Hope this helps someone else who is looking for good lighting. Sorry the pics below don’t do it justice.

rotortuner - Seem like half a lifetime ago that I did that layout. Congrats on your progress and thanks for providing after pics and experience. Your pics don't feel like a 60x68 building.

 

[Toomanytools?]

Rotortuner...Looks nice, those Diva 110W are what I'm looking at for my shop at 16'.
I bought a few of the Diva 70w/8500Ln for my woodworking shop with a lower ceiling 10' to try out. They seem well made so I will order up the rest soon.
Good to hear you like your setup.
You ran ceiling outlets for each fixture and added cords? What was your reasoning rather than hard wire, ease of replacement if ever there was a failure?

I think you will like the 110s, they are nice fixtures. The hykolites off Amazon are pretty much identical, but when I bought the volume from bees with the discount they were only a couple bux different. The divas have like 4 rows more spaced out of leds where the hykolites are like 2 rows a little more centered and more intense. I thought the divas put out just a very slightly more uniform light.

Yup I ran all the outlets... my fingers hurt. Ha. I did it for a couple reasons. First was so I could easily take them down for whatever reason and or easily plug in a new or different light. I also could move a fixture or two to accommodate a lift etc and easily just add a longer cord. The second reason was because I searched and couldn’t really find any good pics of how people cleanly hardwired them with using stapled up romex. The romex would have just had a last staple and then drop down into the light with a pinch entry and then connected inside. That seams kinda hokey and seams like it would be contrary to code or nec. Also would be hard fitting the larger wire nuts inside and also may have affected how the light hung. I hung them on 1” hooks from Home Depot that only costed $5 for 50. This was way cheaper than pendant or flush mount. The screws go right into the wood and the hangers go right on them. Due to lenghths of the strings I used all 12ga which is kind of hefty If they were hard wired, I think they are like a 20ga solid. I’m glad I did the outlets. Maybe some extra work but is clean. Can’t really think of a con other than the extra time investment.

These are the cords I used:
https://www.amazon.com/gp/product/B075WC3LZG/?tag=atomicindus08-20

With that length of cord I put the outlet centered 5” the side of the center of the light. I cut off the female a little into the connector and peeled it off then only stripped about 1” or so. This was the cheapest way to cord them I could find.

 

[nastorino]

Platonic, I wanted to thank you for the layout and guidance that you provided. Life got in the way so I've live without any ceiling lights in my garage for the last 5mo. The fixtures were mounted but the new wiring never run to the existing switches. It finally got a little warm so I hopped up into my attic and was able to crawl through the trusses without having to wear a coat. In less than 12hrs I had all 16 fixtures tied into the existing wall switches, two brand new switches installed, one being a motion. I'm loving the new setup. Thank you

Attached as the excel file I created it in. The screenshot always remains small due to using my wife's 13" MacBook :LOL_hitti

scout4bta - DoD. Requirement is indeed 4100K +/- 297 (to be ridiculously exact). I'm impressed you remember that. For the home garage it really is a personal preference issue. I can go either way, as long as they're all the same.

nastorino - Something like this (link). I don't like putting fixtures 1' from the wall, but we have to work with the space available. If you find the open garage doors cause too much shadow, you could drop those fixtures down.

 

[wantacoe]

Any guidance appreciated. My shop is 43'x50'. 15' white flat ceiling. Lights will probably hang at about 14'. All side walls will be white steel. There will not be much stuff on the walls but the shop will be full.
Whatever lights I get need to be linkable. How many lights can I put on a 20amp breaker using 12 ga romex?

 

[Platonic Solid]

Whatever lights I get need to be linkable.

Why? You'd have to install a sh!t ton of under-powered linkable fixtures to achieve appropriate illuminance.

How many lights can I put on a 20amp breaker using 12 ga romex?

20A x 120V = 2400W / fixture wattage = max fixture qty.

Lowest cost option:
Qty.16 of HB-90W320605-L-D-2 (link) $60 x 16 = $960 (might want to find something for $40 to hit the free shipping $1000 mark)

120W / 120V = 1A x 16 = 16A

The last poster that purchased above fixtures actually received a better fixture than ordered - see this thread (link)

Why? You'd have to install a sh!t ton of under-powered linkable fixtures to achieve appropriate illuminance.


Thanks Platonic, I didn't know linkable were junk, I just thought it would make wiring easier.
16 2' lights will provide good lighting in about 2200 square feet?

 

[Platonic Solid]

wantacoe -

linkable is typically low budget shop light stuff and they aren't available at higher lumen outputs.

Footcandle target for workshop = 93fc @ 30" workplane. 16 fixtures 16,000 lumens/fixture yields 97fc @ 30" ...
