Hi Elliot,
I also have one of Marks Nite-Tek T20 torches. I have one of the 3 mode version that he made last year, I also bought a Uniquefire T20. They come with the Aspherical lens as standard, I bought mine to convert to IR but as yet still have not got round to converting it yet. I am hoping to pick up some blank pills to make up other drop ins so I have the option of changing colours. Or putting in 940 new ostrau black in to see who well it works with my set up.
Great review!
