Selfbuilt did a test on it on CPF and came up with the 3% loss number .
It's definitely as good or better than any other diffusion material I've ever used . I use it on the S2+ Convoy lights that I originally didn't like as much as the S2 Convoy because they were to floody . This just makes them a beautiful smooth beam which I like much better .
It also kills all those super ugly rings from really ringy lights like the Tank007 566 lights . It took me a long time to start using diffuser film because i somehow thought it was cheating or going to kill a bunch of lumens .I agree with "Jacktheclipper" it's a nice addition to lots of lights .
Certainly one of the cheapest things you can do to dramatically change or fix your flashlights beam pattern .
S -series Convoy tube lights in a nice tint with dx-fix on the lens makes a great 'round the house light
Got mine in, thanks! I am impressed, most of the accessories like this seem overhyped, but the DC Fix works very well. I think I will be using this on more than I thought, including o e of my BLF A6’s!
Remove lens from light . Clean it with alcohol . Cut a piece of film slightly larger than the lens . Peel backing off film and apply it to the lens , making sure to get all of the bubbles out . Use a razor blade to trim the film by cutting flush against the edge of the lens at a 45 degree angle .
I usually put the lens back in with the film on the inside . This allows the bezel O-ring to seal properly .
