i just put 3 of these in my 4 car garage and it's brighter than daylight in there now



That's for a drop ceiling. I'm kinda curious how you installed it in a garage and how it looks.

the ones i bought are 7200 lumens each. i will be installing 12 of them for a grand total of 86,400 lumens.

i think that should do the trick. will report back if i get a sunburn from working in my garage.

Here is a layout tool. This will help ensure you have enough light. For anyone that wants to know.

A good rule of thumb is to aim for 50 lumens per square foot for ambient lighting, 300 lumens per square foot in areas that require task lighting, and a moderate 75 lumens per square foot for accent lighting.

hmm, so help me with my math here:

12 8ft lights x 7200 lumen ea = 86400 lumen
30x31.5 garage (lets just call it 900sf since there are cut-ins so thats not all usable space)
86400/900 = 96 lumen/sf? is that right?

putting these in center of room spaced 4ft apart
- 2 per row (16ft)
- 6 rows

surely i'm not underpowering my garage lighting with this 96 feet of lighting.

No, I dont think so, I think you will have tons of light.

Task lighting would light a desk lamp pointed right at a sheet of paper you are working on.

I love the color. Every light in my house is 5000K including my garage. You can see so much better it’s unbelievable.

Bump.

I had someone fix the ceiling drywall (good lord what a mess) and plan to paint the ceiling later this week and start hanging the lights right after.

I have everything i need, just waiting for the last layer of mud to dry & sand one last time.

Only suggestion I'd offer is to make sure whatever lights you ultimately buy have the highest color rendering index (CRI) possible. It's important if you are ever trying to match paint colors, do paintwork on cars, boats, etc. If you're never going to be doing anything where color accuracy matters, then don't worry about it.

Bump. Project is moving along. I had my ceiling issues fixed, mudded and sanded and I finally had a chance last week to paint it. Used the recommended Sherwin Williams Brilliant White and it did a great job. Bought 3 gallons and only used 2 so far but I mainly focused on the middle where the lights were going. So I ended up with 6 rows 16' long each. laser level was invaluable. absolutely no way i could have made these straight without it.

i'm not done; just hooked up power temporarily to each to ensure they work. i picked up some PVC to run the wires in so it looks a little more professional than just romex stapled to the ceiling.

here's a few photos. if you buy these lights ASK FOR EXTRA brackets immediately. they provide TWO frickING BRACKETS per 8 foot light segment. thats criminal. you need 4 minimum per light to prevent sag. i rigged mine a bit using a combination of double-sided tape and placing one bracket close to where the 2 lights join since the lights being connected together helped to hold the second one in place. love the lights so far, hate the shitty hardware they included.

oh and yes my garage is a fricking disaster right now. i'm going to be be painting everything including cabinets but wanted the lighting in first.

first light was the hardest to get correct



shitty brackets


all strips installed (removing the old a19 fixtures when i'm done)

ends i have to wire together


test run (red arrow is box i'm wiring the lights to).

all that wire hanging down i'm going to put inside pvc and paint it to match the ceiling

My concern would be the cool 5000 K color. I’m not a fan. Found something online that recommended 3500 K for garages.

In the end, it is your preference that matters for the lighting color.
