@Matt Carden you will get some diffusion for sure, but, I am not convinced this is the way to go.
Try it, maybe it'll work.
I am going to test it and not be a nay sayer.

Well we will have to agree to disagree on this one.In the plat biology world its fairly well established that you don't put plastics in the light path if you can avoid it. They age and start absorbing wavelengths they shouldnt. I am seeing a lot of recommendations for acrylic, but no one is addressing this. As far as I understand this, it has to be glass.
With respect, I dont think theres any physical basis for believing egg crate does much to diffuse light. I get that it "looks" that way but I dont think this is supported by any data (e.g. PAR values)
I tried taking lenses off. The light cannot penetrate far enough with decent PAR if you remove the lenses. I measured this extensively. Remove lenses on a black box and hang it over >12 inches of water, you cant break 200 PAR even at max power. Removing lenses worked great for a shallow frag tank but nowhere near enough PAR in a deeper display.
To clarify, I'm not taking a stand about whether you can run a tank without lenses. People have different preferences for target light levels.Well we will have to agree to disagree on this one.
On my diy LEDs I don't run lenses at all. Have always gotten good growth
There are folks on this forum who have removed them and have beautiful sps in their tank.
I will take measurements soon on my lastest modified black box. with and without diffusion.
Could it be that we are comparing apples to oranges here? Black box is a generic term for a long list of Chinese led light makers that all make a similar style box but, those manufacturers led's all use different diode's and lenses. I believe some makers have the diodes that diffuse the light and others use a lens to diffuse the light. I could be wrong, but I think this is the case because some use a white opic lens, some it is clear and some colored. I am interested in whatever you'll come up with but would like to know the brand of the light for comparison purposes.
Probably great. However, some may have coatings applied for IR/UV side so if you're looking at passing the deeper violets it may attenuate.
