Building is 45x45x16. Has two overhead doors on one wall and three 36x36 windows on opposite wall. I was thinking 9 lights (three rows of three), with one from each side around 10' from side and one in middle @ 22. I'll also probably have some task lighting by the bench and a portable light on stand.
Looks like it might get pricey but T8's will also be expensive. :headscrat

9 would probably work, they are bright , and if you put task lighting at your bench that helps the close detail work !!!:D

bunk, I've had them 6 months,so far so good. reviews I have read on amazon are mostly favorable -- ymmv

Is 16 feet too tall? Also, at 16' they would have to be suspended from steel beams. Optionally, could I mount them to the beams and angle them so they shine straight down? Although, that would be even higher. The ridge beam (for the middle row of lights) is about 20 feet above floor. Would the light be too dim at 20 feet away?

you could mount them to the beams-- the mounting bracket is just some flat bar bent like a square "U" they are not very heavy, mine are mounted to 6x6 posts with either 2 or 3 #10 wood screws, the lights are about 9x11 x 5 inches deep if it was me, I would put up 12 like I recommended before, 9 will work,the will be bright enough,but I don't know what kind of light you want to work in -- what is bright to you vs. me ? I'll try to get pics tonight of mine. Also, there are 2 colors "cool white" and "warm " I have the cool white -- more "blue" than "yellow"

Pete, Wow, those lights are brighter than I thought they would be. And that's just 6 lights (50 Watts each), correct? I think 9 - 12 in my 45 x 45 would work just fine.
That's a nice looking press!
Thanks for the pics.

I'm using Cree LED's as well in my garage. I've got 7x750 lumen. They are recessed though for a cleaner look. Each one is roughly the equivalent of a 75 watt incandescent bulb. Each one only consumes 11 watts so running 7 of them is just a little higher than the cost of running a single 75 watt incandescent. I have them on a dimmer for when the brightness overwhelms me, but most of the time I run them at full power.

I have one LED flood in my barn that I replaced a cfl with. Regardless of temperature, the LED is instant on. The cfl's in extreme weather take a good while. The spread is not nearly as much with the cfl, so you don't cover as much area as a rule.

I am considering cfl's in can's for my basement. I see the fixtures are much more expensive than the general purpose cans. Why? Can a person simply use an LED in a conventional can?

I would think CFL's in a general purpose can shoud be fine, as should the LED flood light replacements. Maybe the fixtures are bulit more around the CFL type bulb? I know if you stick a small CFL in a big can they look a bit weird visually. Or maybe they just figure they can charge more since it's a different technology and people will pay it. Who knows.

FWIW, I’ve been adding some outdoor LED flood and area lights. This link will drop you in my build thread where the story starts: Reply #2494

If you scroll down once you get there, I’ve included a couple nighttime shots to give you some idea how much light these things really put out. I will add more info as I finish it up.

I'm trying to get an idea of how well these stand up to thermal cycling. LED's circuit systems, especially in the 50-55w range are going to have a lot of heat to manage and typically the temp cycling is what leads to their failure...so here are a few more questions:

What’s the various ambient temp ranges these have been working in?
(Are you in working in 95*F weather? Are you working in -10*F weather? Are you working in a heated garage that starts out cold as you get started and you get things warmed up as you get started? Full time AC?)

What's the average run time when you have these turned on?
(1 hour, 12 hours, 30 minutes, ....so on)

How often are you turning them on and off?
(Once a week on the weekends, once every day, several times a day as you go in and out, ....so on)

Ever put your hand on one of the housings after the lights been on for a few hours? How'd it feel?

Thanks
Wes

wow, lets see, #1 never touched them after on,because they are 12 feet up.
#2 no heat,no AC I'm in the PNW -- today it was 20 degrees -- mostly though 35-45 winter 50 - 75 summer it varies

#3 when I am working, I'm not in the shop,they may not be on all week, when I'm in the shop there on whatever time I am there 15 min - 10 hours - just depends

guess that is all I can tell you.

It's been -10 to -14 in the morning the last couple of days and I haven't noticed any issues with mine which is the same as Pete is using only 10W.

Can you post some photos of the light output from the 10W model?

I just ran out and got a quick shot for you. It's not great but it's dark out and it was hard to get a shot of the light output. The picture doesn't really do it any justice. I have the light pointing pretty much straight up for my flag. As you can kind of see, the side of the house is lit up from the light. Also you can kind of see a tree in the background, this tree is about 50 feet or so back. There is another tree that you cant really see that is behind the house, about 75 feet that is also lit up. There's more that you can see in person that my phone just can't capture. I don't think the snow is having any effect on what you can see around it since the light is pointing straight up, but regardless, it lights up a lot for only being 10 watts. :shocking:

Also, for what it's worth, it's also 2 degrees F outside right now and the light doesn't seem to care.

Has anyone put these 50 watt LED's overhead from 16 - 20 feet high? Do you still get plenty of light at the floor?

I put two 55W LED floods in my garage at 8' and they make it daylight in the garage for these old eyes. I would certainly believe that the extra 8 - 10 feet wouldn't be too much for them.
