I’m not a C8 fan really. I have had several but most were just OK. I had a good one with a nice tight spot but it shorted out after a wire got pinched when tightening the head which came loose from the factory.
I have a run of the mill Ultrafire C8 with the half OP reflector that I got from Wallbuys for $5 or so. It was ok but the hotspot wasn’t as tight as the good one I had briefly. I decided to try a de-dome.
All I did was pinch the dome off with my fingertips and it came right off. Easy. The hotspot is much tighter and it seems to have a slightly warmer tint. All good stuff.
I think the C8s with the half OP reflector lend themselves well to de-doming because it cleans up any artifacts that would normally appear.
I de-domed my Dongui light which looks similar to a C-8 but already had a tight hotspot. The result was not so great. It is a tighter hotspot but kind of ringy. Looks like a titely focused Maglite now. I was happy with it before so kind of wish I hadn’t messed with it but I didn’t ruin it or anything. The artifacts and ringy pattern are not visable outside so it is still very useful but I now like my C8 more.
This turned my C8 which I had no love for into one of my best throwers and it is in a single 18650 size so it’s great. My Solarforce MPP1 is still my fav thrower but for a $5 C8, I’m pleaded as punch.
