That looks pretty slick. Are you thinking of lighting your whole garage this way or is this for task lighting?

I might suggest you have a good read through the Lee Valley primer on LED lighting (especially their "getting started" guide). It isn't a very straightforward thing to do, as compared to normal lighting fixtures.
As was mentioned in your other thread, you might want to stick to a reputable manufacturer. They may cost a but more, but the cheap DC power supplies I see are a bit of a fire hazard.

I was planning to do something similar today, but the 4' flourecent were better in every way, including lumens per watt. I just bought a box of 2850 lumen, 6500k, 38 watt for $3.50 each at HD. Will post pics tonight sometime, check them out.
That is 75 lumens per watt. (which is even low for fluorescent) 90% of LEDs are running between 95 and 125 lumens per watt. Also, 2850 lumens out of a LED will produce more light than 2850 lumens out of a fluorescent. Simply due to the fact that the light coming out of the top 180 degrees of the fluorescent has to somehow be reflected back down. And you will never get all of it. Just for easy figuring, say 25% of the total light output from the fluorescent never makes it to the ground. That takes the 2850 lumens down to 2137 lumens. Now you have gotten down to 56 lumens per watt of useable light.

What this guy said...
What are the dimensions of your garage...length, width and ceiling height?
18x26 12 peak height with cathedral ceiling
That sounds like a perfect situation for a couple of high bay lights. I partitioned off 24x40 (13' 4" ceiling) and put 5 high bay LEDs from Home Depot in there and it's darned near like daylight. One corner is framed out as a bathroom/utility room, so I didn't put a light over that, or I probably would have 6.
With your shop dimensions I think two would do okay, and three would be awesome. I have two of the same lights on the 40x40 side and it's not bad, but there are shadows around some of my equipment.
They're $159 each, so not cheap, but I really like the light output and color and they should last nearly a lifetime in a hobby shop that's mostly used on the weekends and evenings.

This is a very old picture, but it will give you an idea what I'm talking about. The far right corner is where I framed out as a bath and utility room, so I didn't put a light over it. Other than a light pointing directly on a work piece, I can't imagine needing anything else.
A much newer pic looking from the other corner...you can see the shadow over the bath/utility room, but nowhere else.

The new Philips 12watt Instantfit is up there with a luminous efficacy of around 135, 1650 lumens at 160 degree beam angle. We just did a building retrofit with them.
Brightness in this space is at a low of 50fc, to a high of 65fc. I've reduced exposure here so the lights were not blown out..it's actually a lot brighter than it looks. We removed Philips TL-950s (5000K, 98CRI) at 32 watts rated at 2000 lumens. The perception by my team is that is 10-15 % brighter in there now as the Instantfit 1650 lumens is directed to a 160 degree beam spread, instead of 360 as in the flouro tubes.

G-ManBart - I'm considering those high bay lights for my new garage, and have read numerous reviews stating that bugs get into the fixture through the cooling holes. Have you experienced that? It would be a big problem for me, because the lights would only be accessible from a lift.
Thanks, Cory
Thanks, Cory
Hey Cory,
I haven't had a real problem with bugs in the lights. I have 7 total and I think one of them has one big horsefly in it that I know of...other than that, I haven' noticed any bugs. I haven't really thought to look, but I will try to check them tomorrow.

Well I went a little different route. I used 30W spotlights for my inside lights. I personally like how bright they light up my shop, and use low power.
Here are a few pictures of my barn. They are from LightingeverLTD The one that's not lit, went out but the company is sending me another one. I have mine all ran on doorbell wire, and have 6 or 7 on each run. I paid about $21.00 each and had free shipping. Of course I have bought about 50 of them cause I like a very bright shop.

I'd suggest this is out of your league. This is an import item, of questionable quality and specifications. I'd stick to main name suppliers were I you.
