how many LED would you recommend?

[pointer80]

Hello guy's, I am finally to the point where I am installing osb board on the ceiling of my 30x30 work shop and I am in the process of figuring out how many 4 foot led fixtures I need to install. I would like it bright. I plan on eventually painting the ceiling white to match my walls. My sidewalls are 10 ft. high. I plan on mounting them right to the ceiling and hard wiring them in. What is your guy's recommendations? Thank you

Here is the layout I am going with. I think it will be pretty bright based on some testing with a few temporary fixtures. This is a 25x40 basic footprint. Time will tell if there is enough light

Basically I tried to make it easy on myself by being able to use the bottom chord of the trusses 2ft on center. Then space the fixtures with a 4ft gap in both directions.

The Costco Feit fixtures are linkable, meaning 3 can be daisy chained with the 4th actually plugged into a duplex. While you can use that feature to save wire and boxes, twisting and terminating, I didn't want to be tied to that forevermore (without a major tearup of the planned drywall ceiling) in the case that something better comes up in the future. Also, in case there is a specific task I want to illuminate better, any of the LEDs could come out and be replaced by a 4bulb T5HO fixture, up to the point where the circuit runs out of amperage....but I don't see that need except maybe for 1 or 2 places. Again time will tell but I have the flexibility built in.

24 x 24 here and I'm going with 8

I'm using the Costco 4' 2 Bulb LED. I have 2 currently in 1 bay and it's bright already, enough to easily work, and brighter than the old-school buzz lights. The rest I still need to put up. I only have 8' ceiling too, your 10' will throw even further than mine.

Just remember, it's easier to turn on another switch for more light than not have enough.

My garage is 18'x19.5'x8'. I have 8 of the Costco fixtures, a 1000 lumen LED bulb in the old porchlight wall fixture and a single, 4' LED bulb above my workbench under the upper cabinet. It's BRIGHT with the garage door closed and I love it. I'm using less than 10% of the power when I had T12 and then T8 fixtures.

I've got a 22x20 with 9 using the sylvania LEDs from Home Depot and am pretty happy with the light. 10' ceilings.

You will need approx. 30 2 tube fixtures. 24 minimum, depending on output.

I think you may be to bright. Personally I would take out one of the sting of lights. Leave them all and use 2 switches. Then you get to choose your light levels.

I like the looks of your lay out, How high are your sidewalls? I am thinking of using 2'x4' drop ceiling light fixtures converted over to led. Thoughts on this? Also are you mounting your lights to the ceiling? Thank you.

I plan on doing 16 of the Costco leds in my 30x49x10

I plan on 9 led 4 foot fixtures in my 32x32 2 bay shop.

My ceiling is 10' 3" from the concrete floor, I'm thinking that its going to be -(5/8") due to the drywall

I mounted some in my other shop using "acoustical eye lag" screws I found at Home Depot...you can google that term to see, sort of like a lag bolt with the head cut off, the unthreaded shank smashed flat, and then a hole punched thru the flat. There is a metal impact driver bit for efficiently driving them, Dewalt DW 2225.

I was going to snap some lines on the rough drywall when its installed and then put in the lags, in case there were any "errors" in finding the wood, I can fix them while mudding and taping.

The Costco Feit versions come with a couple little fine steel cables with a question-mark hook and a crimped cable-eye, about 4-5" long overall. While they are supplied free and work great, they are a little longer than I wanted, so I'll probably order a spool of stainless steel lockwire or piano wire and bend my own, shorter. But any wire or cable could be used, strands of copper would probably be just fine imo.

Using drop-ceiling lights would probably work just fine, are you putting them flush with the ceiling or surface-mounted from under? If flush mounted I'd want to do some good air sealing so that heated air doesn't constantly leak into the attic.

I was going to surface mount them right to the bottom of the ceiling
