I recently bought the Dereelight MC-E pill and the Dereelight LOP P60 setup (outside spring as well) for my CL1H, but ended up dropping the whole thing into my Pila Gl-3. It works great so far based on nothing more than some quick outside tests while walking the dog. Was wondering if anyone else is running a MC-E in their Pila and what their impressions have been? (heat build-up, battery life, etc.) I'm using Pila batteries in mine...
