Fixture idea, please discuss

Approx 24x24x8" for a 4x4 room.
4x@150w clu058 on 2 meanwell hlg320-c2800.
All the room air sucked through the heatsinks.
About $450 plus duct and wire.
Thoughts...thanks.

Bit hard to see much from ur sketch but should work

So u will have the heatsinks on a frame and duck from around the heatsink to central duct and out?

Seems overly complicated to do each heatsink on its own duct

You could just have the heatsinks perm inanely installed so the pins/fins stuck
Out of the grow chamber

I don't care what anybody says, I like it! Nice to see somebody planning on making the most out of CLU058s. 150W each is #1 in my books.

Sick.. That looks like a sentient being.

Weed, sorry about the poor sketch, my hand is a meatball with 5 sausages.
Basically a std 8" duct used as a manifold, closed on one end, with 4 1-foot hoses that fit over the heatsinks and vacuum it. Looks complicated but just a few holes to cut and keeps the fixture mobile (up/down) and should be relatively small 8" height. I do like your idea but then its cutting four holes in a tent..

Electrical criticisms? Better driver choice? I think this woukd be fun to compare to 630cmh.

Nope, nope, and yup.

Well now to figure out airflow, heatsink and fan size.. Got a 760cfm inline i hope will cool this thing and suck thru carbon.

Thats a pretty cool idea.
I've drawn up something similar in thought. Hindsight, I'd round off my corners quite a bit..

Can be made from an electrical panel. Cut holes for pinsinks and cut the center and bend the cuts upwards to make the inner walls that channel everything.

I mean that's plenty of air if it's not a booster fan, and as long you don't have the flow too restricted on the heatsink ends.

Optics?
I reckon im not looking to focus the light with reflectors.. 4x4 with 7' height. Diffusers?
Sorry boys i cant like posts yet

I use open BJB holders for my 50W 3070's and the spread is NICE. I can only imagine how well your spread is going to be with clu058's @ 150W ea. before any diffusers or silicones

Solve for angle Y

Solving for Y in above sketch is @27degrees x 2 = 54 degree total spread to throw all light on canopy and not onto the walls of the dead zone between light and top of canopy.
That means significant reflector would help.
A moot point since none of my math seems right, and because bouncing that shit off the walls is probably good enough?
