Xr15: diffuser vs 120 deg lens

tenurepro · Jan 2, 2018

Hello Ecotech and ecotech users!
I currently have 3 radions xr15 gen 3 mounted on my Redsea reefer 250... I have the 120 deg lenses installed on all three to reduce shading and hotspots... lights are using sps ab+ with max intensity of 70%

So I am very curious about the xr15 diffusers; I actually purchased three for my tank but haven’t received them yet.

I am wondering:
1) are the diffusers better used with the 80 deg lenses? I am guessing this is the case but would be good to hear other’s thoughts on this

2) what are the benefits of diffuser + 80 deg lens over the 120 lens... do the diffusers do a better job of evening out light coverage vs wide angle lens?

Thanks!

I run standard lenses with the diffusers

Ok... wow
80 deg + diffuser seriously outperform 120 deg wide angle lenses!

Hi All. I got several requests for a full comparison of the diffuser on both the 80 and 120 Deg lenses.

In summary
In terms of par, we get
80>80+D>120>120+D (where d= diffuser)
In terms of Best spread of light, we get
120+D>120>80+D>80

For me the best compromise of par and spread came with the 80 deg lens plus diffuser
