I'm curious, how much is it worth? It is my first SureFire, I bought it 1998 from Lagger-Pro. Flashlight is in good condition. Recently I tried RCR123 cell (stupid) and burned original R30 3V drop in. Inside is now DX led drop-in with SSC P4 led.
First of all, it's a 3P. Second, it's the first single cell light offered from Surefire, back in the early 1990's. It's built like a tank but quite weak in performance by today's standards. You will most certainly want to invest in a Malkoff (or similar) drop-in LED module for this light. If in perfect condition, the current market value is probably around $100.
