Hi guys. First, let me say that I am new to flashlights(real ones) and know absolutely nothing about modding them. I have a Mag 4C light that hasn't been used in years. I hate using it because of the "rings" in the beam. My question is this. Is there a simple mod that can make this light brighter and with a better beam. Keep in mind that I want to keep this as simple as possible. I would rather not have to fabricate anything, a "drop-in" would be the best for me, especially an LED. I am an ARC nut so I am obviously a fan of LED lights. Anyway, any guidance would be appreciated. Thanks.
