5 of 5 Green Filter September 17, 2023
Reviewer: Robert Wieneke from USA  
I have NFR32 Red 32mm filter assemblies on all my Streamlight TLR-1 HL's They work great. Wanted one Green filter but Nightcore doesn't offer a Green filter lens in the 32mm cup. So I bought the NFG34 34mm Green filter assembly, filed the lens down to the same size as the Red 32mm lens filters and put it in one of the 32mm rubber cups. Works great.

4 of 5 34mm Red Lens June 25, 2021
Reviewer: Justin Nordquest from San Diego, CA United States  
The lens itself works wonderfully.  It only dims the brightness a fraction while making the light suitable for maintaining night vision.
The lens cap, on the other hand, does not fit snug enough on my i4000R.  I will have to use adhesive in order to hold the seal.

1 of 5 Red filter cuts lights power in half June 28, 2020
Reviewer: Matt Spencer from Madison, AL United States  
Was pumped to receive my MH25GTS and red filter as I planned to use it for coyote hunting. Once I put the red filter on out in the field I was super disappointed to find that my 950 lm light was putting out half of the power of my buddies 800 lm red filter light. This filter drastically cuts down on the power of the light.
