LED panels in garage.

[APG12]

I’m thinking about installing these 2’x4’ led panels in my 2 car garage:

Each panel is rated at 8500 lumens and dimmable.

I’m attaching a picture of the garage layout. Ceiling is 8’.

Can anyone help me with how many panels I would need?

Thanks!

Those are designed to sit on a drop ceiling in the same "slot" where a 2x4' tile goes. In a office setting, you would have 4' in between each light to the next one. So there will be two tiles along the narrow part and one along the long part between each light.

How are you going to mount these? There are other similar lights designed to mount flat against drywall where only the electrical box goes above the drywall. These aren't them.

The have frames to flush mount that are around 2” deep. I’m open to other options...

Look at the lighting diagrams in the layout thread. You will get an idea of what works for light spacing and the number of lights. With your low ceiling, you want the flat panels or wrap lights. Wrap lights will be cheaper since you don’t need to buy surface mount frames.

Which look just like the cheaper Hykolity

Sometime in the near future I plan to be flush mounting mine. The driver will go through the ceiling and the light will be wrapped within a slimline wood frame. Looks good on the puter for now. I know, extra work.

8500 lumens from a flat panel is excessive. I wouldn't use this fixture based on that alone.
Also, with your low ceiling, it's too much light from one fixture. Use more fixtures that deliver fewer lumens and you'll get a much better lighting result. If you have a finished ceiling, consider surface wraps or a surface mounted linear. Something in the range of 5000 lumens per fixture is the max that I would use.
Good luck,

I've installed these suspended in open ceilings. The tabs on the back have holes, I hung them from jack chain and dropped my bx down the chain from the deck.

Not my design.

I've also hung from aircraft cable

I completely missed the 8500 lumen part. That would be extreme at 8' if the 8500 lumens is really correct. I used the Pixie lighting version, which are realistically rated at 4800 lumens and they were excellent with 4' in between each light to the next in a 10' drop ceiling.

Don't forget that none of these seem to be very efficient at 85-100 lumens per watt so you aren't getting much light for the energy consumed.

These are an option too. 2x2 at 4300 lumens.

I’m trying to get away with less fixtures if possible and I like the look of the panel lights.

We have a few of these in newer remodeled areas at work. They look just fine but I'd not drop $80/each for them for the shop. I don't remember exactly but I want to say in the 8' ceiling grid they are spaced 8' on the long side and 4' on the narrow side. About every 3rd ceiling panel.

Using fewer fixtures is a self defeating strategy. I understand that it's good to keep the costs down, but try to understand the following:
High powered lights are designed for high ceilings. If you mount them too low, you get one big hot spot on the floor and dark spots surrounding it. You get really dark shadows everywhere. The place will look really bad.
Flat panels, by nature, are glarey. Glare is especially harsh on low ceilings. Glare is magnified by having fixtures that are really bright. You are looking at really bright fixtures, that are really glarey, and low ceilings. Not a good recipe.
If you like the look of flat panels, that's fine. Just look for either a 2x4 that's 4000 to 5000 lumens, or a 2x2 that's 3000-ish lumens. Then, space them properly and you'll get a nice even, well lit space.
Good luck,

This makes sense. I don’t really have a grasp on lumens, so I’ll take your advice and look for something a little different. Thanks!
