Not quite as expected

by Legacy Reviewer, Verified Owner from CO, United States Written on January 4, 2012
I was disappointed with the output when using it on a SureFire 6P light and a 1st Gen Night Vision device. The output was so low that it was basically useless. It may work fine with a dedicated illumination flashlight, but I cannot comment on that.
Pros: Ease of use, installation
Cons: Not really useful on 6P
Would recommend: Yes
