The head of the P1 CE houses an XR-E emitter and focused by a textured aluminum reflector. Emitter and reflector are aligned very well, perhaps leaning just a hair to one side but really it's almost perfect. The lens used is made or hardened AR coated glass for increased light transmission as compared to regular uncoated glass. The head has a band of diamond textured knurling which makes it easy to twist for single handed operation. The hexagonal faces machined on the battery tube does help a little. The emitter module is sealed inside the head and is not easily disassembled. Something different about this Fenix model is that they have opted to use brass in the head module for better heat management.

They body of the P1 CE is pretty compact when compared to other single CR123 powered lights out there. It will easily fit into any shirt or pants pocket without being too obvious, but more suited to be carried in the supplied elastic holster. The entire light is coated in Type 3 anodizing. One thing to note is that the coating on the current line of Fenix lights is smoother and more shiny compared to the earlier LxP series of lights. Anodizing is extremely well finished, clean and smooth, without any marks or scratches. The aluminum body of the P1 CE is quite thin, but this in turn makes it very light. I doubt this would make the light any less rugged though. Inside the body is all nice and cleanly machined. The threads on this light are almost perfect. They are very smooth and free from accidental cross-threading, you won't need to turn them counter-clockwise to get the threads to align. Throughout the entire testing phase of this light, I did not experience any sign of cross-threading. Take note that UltraFire's gray protected 16340 cells with button tops are a little too long for the P, and part of the rubber o-ring will be exposed.

The P1 CE is a standard single mode flashlight. Some people may see this as a step down since Fenix has been releasing multi mode lights lately. The fact is, there still are people who appreciate simple these simple single mode lights. Another advantage is that the single mode circuit in the P1 CE is more efficient than the multi mode circuits. Overall the output is very nice and bright. The beam is smooth thanks to the textured reflector. Tint is very white, perhaps just a slightly on the warm side. As you can see, the battery life is at least 30% better than the multi mode Fenix lights such as the P2D CE while giving slightly more output too.

The Good - Nice compact size, efficient circuit and very bright output.

The Bad - Battery tube is slightly too short, noticeable gap between the head and battery tube. Rubber o-ring is exposed when using longer 16340 cells.

The Relative - Only has a single output mode which is very bright, so it's more suitable for a specific use.
