The best for 315CMH lights is stainless steel. But I have way too much wall space, without the deep pockets.
Will be beginning with my small room. Should take 50' of 4' using Vivosun Diamond reflection. Bought a roll of 50' for about 50 bucks.
The kicker is the 315CMH lights. Extremely picky in their reflection. Tried Orca (major wilting), white sheet paper (same thing), then tried blackening all walls (no reflection is BAD, reflection for lower leaves is a must) then temporarily using dull sides of aluminum foil...
And that worked. Finally. So I figured to get the good stuff from the maker of both the light and bulb too. If this does not work, I will be completly surprised.
Should receive first shipment on Thursday the 1st. Will hang pretty quickly after receiving...
I realize I have not followed up with this thread. Must understand this is my own personal feedback of this product. There is nothing to it, did not receive for free and this is not "officially" proved in any way....
Now with that out of the way...
THIS CHIT IS AWSOME!!!!!
Will send pics below. What I needed was a dispersal of light in a bad way. I am using 4- 315CMH lights, to cover an 8x4 tray. 12 plants.
I am able now to lower lights through out room with very very little yellowing at all. Just now I have lowered my lights to beyond 11k lux finally, with no I'll effects...

Ps, will follow up with up N comming pics. To see exactly where I can get higher lux over all on plant, again with no ill effects is needed.
So we will see...
