Warehouse lights

[Iroc-Z]

Looking to see if anyone has put old style warehouse lighting in there shop. I have old galvanized ceiling and think t8 light strips won't fit the look I want. I was thinking something like this
http://www.barnlightelectric.com/discount-lighting/warehouse-lighting-1/#/product/61985

With a dimming 85 watt led bulb.
https://www.1000bulbs.com/product/137218/CM-CMC902501840.html

Any input would be great.

Does this mean 85 watts makes 1100 lumen’s? At 13 watts that would mean I would need about 7 bulbs for for that amount of lumen's.

I love the look of the old stuff. I know it's been done before and that others will chime in...
Using old style fixtures with new technology lamps is a really cool idea.
As to the lamp you'll use, understand that the fixture was originally designed for an incandescent bulb, so an LED bulb might make the fixture look and perform differently. That's not a bad thing, just something for you to be aware of.
Which fixture are you looking at?

No. Dis 13 watt LED is an 85 watt equivalent. What that means is that the amount of light a conventional incandescent 85 watt bulb puts off will be put off by this bulb using only 13 watts.

This site was extremely helpful when I was planning lighting my workshop.

He recommends between 50 and 100 lumens per square foot, or lux I believe. To me, with 1280 square feet to be lit, that's pretty excessive... I'm going with 4000 lumens per led fixture, for ~25 lux, (led 4' double strips for cost efficiency), and filling in with warehouse lights for task work.
With LEDs.

50-100 lumens per sq foot sounds like allot

I'll try to stop you before you go down the wrong path.
He recommends FOOTCANDLES. You cannot divide the amount of lumens from the lamps by the square footage of the space. That's not what he means.

Thanks. Upon rereading, and I was quoting from a questionable memory, 1 Lux is roughly 10 foot candles.
Either way, that's a pretty good site. It's not necessarily up to date when it comes to LED technology, but it does have a pretty good description of light and how to use it. To light of workspace.
One thing to consider when it comes to LEDs is directionality. Unlike a conventional incandescent or round or cylindrical fluorescent bulb, most LEDs are directional, more like a spotlight, and shine in a particular direction. What that means is that from a similar output of lumens you actually get more effective light out of an LED because you have to count less on the reflection.

Yep! Lighting calculations are more complex than that.
Maybe just put a few up kinda temporarily and see how you like the effect. Then you can decide on spacing and bulb options.
I love the look of those old style fixtures and there are many choices with screw in LED bulbs. Brightness and color temperature.

People always read that article and interpret it incorrectly.
And Garage Journal forum posts are notorious for misinterpreting it. As a lighting guy, I can understand why, so I try to explain it.

Yeah, I know it's a lot more complicated than that, but forgetting space lit, it's a pretty good article. I think one of the things to look out for is the 'feeling' of the space... it sounds like I'm doing today exactly what the original poster is doing, is putting up my lights. I really like the look of the warehouse lights too, but to me its important to backfill behind the pendants to eliminate some of that cave like feeling that can come with lower lights with a lot of dark space behind it.

Could you give me your opinion on how many of the above fixtures I should put in my shop and what watt bulb you would recommend? My shop is 2000 square feet with 14 foot ceilings.

 

[cybrdyke]

IROC- The link you provided takes me to a page that has alot of different fixtures on it. Which one, specifically, are we talking about?

Part #
20BL14CL-Grey

 

[cybrdyke]

The website doesn't mention who the manufacturer is, so there is no photometric file for any of their fixtures. But...they have a customer service line. I'd bet that they will do it for you. I wont be at my office computer where the software is until next week.

Found fox valley fabrications is doing the same idea I want

 

[Iroc-Z]

He is running 85 watt CFL bulbs.

It's a good look, aesthetically.
The lamp in your original post is 13 watt LED, equivalent to an 85 watt incandescent lamp. It puts out 1100-ish lumens.
The CFL in the Fox Valley pic is actually an 85 watt lamp that puts out 5500 lumens.
That's a big difference. You would need alot more of the 13 watt LED than the 85 watt CFL. Which lamp do you prefer?

I bought 10 14" antique enameled barn/shop lights off EBAY.

They still have the original UL stickers in-tact. They are rated for a 350 watt bulb. I would size any light I put in them accordingly unless you're just wanting them to be non-functional decorations.

Glad I posted. I thought watts would make the same lumens. I guess I really don't understand lighting.

 

[cybrdyke]

Most folks do. It was probably true once upon a time. Not anymore. And definitely not with LED.

So when looking at lights lumens are most important when it comes to actuall light.

Correct.
Lumens is the amount of light coming out of the lamp.
You will also have a choice of color in Kelvins. Warmer colors, like you might use in your home have a yellow-ish tone and will be 2700 to 3000 Kelvin.
Cooler colors, like you might see in a school or a hospital will be white and will be 3500 to 4100 Kelvin.
Coolest colors, like you might see in a workshop or laboratory will be blue-ish and will be 5000 to 6000 Kelvin.
Color is strictly a personal choice. Get whatever suits you best.

Cd,
Thank you for all the input. You saved me from wasting money and a ton of frustration.

 

[Iroc-Z]

Well after thinking about this in depth and what I am using the shop for i decided to scrap this idea and go with 8 foot t8 fixtures. Picked up 20 tonight. Now just need to decide if it will be enough and what the layout will be.
