| 1x DX 3W Cree CM1 3.2V-9V |
| Construction |
The CM1 is a value priced P60 compatible drop-in module which fits in lights such as the SureFire 6P. It also fits in most of the UltraFire or similar lights which run on 2x 16340, 18650 or 3x CR123 cells. The reflector has a medium textured reflector which is very well finished, it's just slightly off-center with the emitter. The emitter and electronics are housed in a separate module which screws on the back of the reflector. There's a rubber o-ring and plastic film placed between them to prevent a short circuit between the "+" and "-" solder pads on the emitter. The emitter is soldered onto a octagonal PCB. A good amount of thermal paste has been applied between the PCB and aluminum housing of the module. All parts of the module fit together very well. |
| Output |
The CM1 has a wide input voltage range from 3.2V-9V which means you can run it on a wide variety of cells. It's safe to run 2x 16340 or 18650 cells fresh off the charger. The beam produced by this module has a medium hotspot with a smooth corona. The corona is somewhat skewed to one side due to the off-centered emitter. The tint on my sample has a cool color temperature with a slight violet tint.

| Conclusion |
The Good - Nicely made with good heat sinking. Able to run on a wide variety of cells.
The Bad - Slightly off-centered emitter which effects the corona in the beam profile.
The Relative - Cool beam with a slight violet tint. |
