Diamond light louvers

Can someone with access to a Diamond light tell me the dimensions of the "holes" in the louvers? Length, width, and depth please.

Seems these are square. If so, the length and width will be the same.

If hexagonal, then one dimension across the hex and the depth will do.

Thanks in advance. My old boss does fantastic woodworking, and I have an idea for a 4' x 8' LED pool table light.

Thinking of staining a nice 4' x 8' piece of plywood cherry to match my Diamond Pro, throwing the usual array of LEDs in there and hanging light louvers below the LEDs.
 
are you talking about the diffusers?

If so, I'm pretty sure they are the same ones you can buy at home depot.

I have the ones from home depot and it works PERFECTLY

Probably. There is nothing special about them. They are coated plastic and the openings are roughly 1 inch square (without actually looking at mine right now).
 
They are nothing like the ones at HD, they are called parabolic louvers. They are awesome, expensive and worth every penny. You can find them at electrical supply houses. Get the ones with the 1/2" squares. The holes in the top side are smaller than the holes in the bottom side so you can't see the light source just the illumination. Absolutly awesome invention.

fyi light fixture lenses are smaller than ceiling tile panels be aware!!!.

I do not like the light output of my diamond light which has 4 circuline tubes.and parabolic chrome diffusers, cubes are 1/2"x1/2"on my factory model 5'x22"wide outside wood frame dimensions
This is for a 3/12 x7' diamond table.!

I hung mine with 1/4"aircraft cable that is easy , thin ,high strength plus looks good !

I think the ones at the box stores will be ok all respect to el nino

I think the fixture inside is the key and I would go with the2/ 1x4 , t8 2 tube daylight easier on eyes but love led in all my other lights!
lol

This ^^^^

The panel light grids at the big box stores will work, but they are cheap pieces of crap compared to the real deal. I had them at first for a while, because the real parabolic louvers are kind of hard to find, and when you do, they are pretty pricey.

I got lucky when my brother-in-law was running a commercial remodel at a hospital, and brought me a whole stack of them that were otherwise going to be demolished. Even then, I had to cut them to fit my light.

Yes, it is definitely parabolic louvers I'm interested in. I assume that is what Diamond uses.

I'm looking to use two 4'x4' or four 2'x4' parabolic louvers suspended below the 4'x8' plywood "deck".

The parabolic louvers restrict the light output to a certain angle. Chosen wisely, they can illuminate the table but not the surroundings.

As I have a front projector in the same room, this is ideal. Now, is there anybody out there with access to a Diamond light that is able and willing to measure the louvers?

As mentioned above, the "holes" are smaller at the top than the bottom in a parabolic louver. This would be great general information for anyone building a table light. Anybody have a set of calipers and access to a Diamond light, please be our hero.
 
Home Depot and Lowes both carry parabolic light fixtures on their website at reasonable prices.
 
Thanks, but I'm not looking for parabolic light fixtures. I'm looking for the dimensions of the louvers Diamond uses. At this point, I don't know if Diamond uses parabolic louvers or "egg crate" louvers.

I've tried to attached a JPEG of a parabolic light louver showing typical dimensions. If it works, I'll attach a JPEG of a double parabolic light louver.

And here's a double parabolic light louver. I'm leaning towards this style with its higher efficiency and smaller shielding angle. Both of the louvers shown happen to be from Louvers International in Elmhurst, IL.

I'd also be interested in learning whether the Diamond louvers are "flange" or "no-flange".

After reading about these parabolic louvers recently I got thinking maybe I should build me a better light. I called Louvers International and spoke to Carl, and he recomended the double parabolic Para Image 4. He couldn't give me a final price, but he guessed I'd be out about $85 for two 2' x 4' louvers after shipping and handling.

That's not so expensive sounding to me, a lot cheaper than I feared they'd be. LI gave me the number for a distributor only a few miles away. I think I'll go with them if I move ahead with this thing.
