My Peak Pacific lens is loose does anyone know if it is possible to take the lens out and replace it.
I did a Seoul upgrade to a Peak Glacier Bay renently, and was surprised to find a plastic lens. I couldn't send the light back with a plastic lens after doing the Seoul mod. So, I installed a mineral glass lens that I got from a watch repair shop on e-Bay. They sell the watch crystals (flashlight lenses) sized in fractions of a millimeter, from 12mm to 36mm. If I remember correctly, the Peak took a 18.8mm crystal.
The lens is held in place by a retaining ring with two notches on it. Needle nose pliers fit into those notches to remove, or install it. You might try simply tightening the ring first, though. I liked the results of replacing the lens, as did the CPF'er who received it. You can see the ring with the notches in the picture here at approximately the 2:00 abd 8:00 position.
