| Construction |
This diffuser is made of a translucent, plastic-like material. It has a texture grain on one side which diffuses the beam profile, and a smooth and glossy finish on the other. The smooth surface is perfect for having adhesives applied if you wish to permanently apply this diffuser material to any surface. As the description says, this material is available in either 5 or 10-layer. For the sake of simplification, the 10-layer is a thicker material having twice the amount of diffusion texture compared to the 5-layer material. They are both actually negligibly thin and will not affect the fitting of you flashlight when used. It's best to place the diffuser on the inner face of the lens of your flashlight, as you won't have to apply any adhesives. However if you're unable to disassemble the head to access your lens, you may apply adhesive to stick it on the outer face of the lens. Either method will result in an identical diffusion effect. Do take not that since these come pre-cut in squares or rectangles, you will need to trim it to a circle to fit. |
| Output |
Below you will the how output the 5 and 10 layer diffuser material affects output intensity and overall beam profile. The following sample shots are done with a generic P60 compatible Cree XR-E module with a textured reflector. This diffuser will have a much more significant improvement in beam profile when used with flashlights having smooth reflectors or ringy beam profiles such as MagLites.

| Conclusion |
The Good - Allows any casual user to easily modify their flashlight's beam profile with no complicated modification knowledge or equipment. Results in a smooth beam with no artifacts. The Bad - Requires steady hands to cut a clean and neat circle for your lens. Alternatively, you may want to use a a protractor with a blade attachment. The Relative - Diffusion of the beam profile results in an overall reduced perceived brightness. You can purchase these from FASTCAR's sales thread here: |
