Bezel: Reflector in Dereelight CL1H is built from solid Aluminium. The reflector has Light Orange Peel (LOP) Finish. Cree XR-E LED is perfectly aligned and centered within reflector. The depth of reflector is medium offering optimum combination of throw and side spill.
Reflector Comparison: On the left you can see a smooth reflector inside CPF Special VB 16 and on the right is the LOP reflector in CL1H. The main advantage of LOP reflector is that it offers a fairly good beam with no artifacts in comparison the smooth reflector has ringy artifacts.
Components of highly modular bezel of Dereelight CL1H. Showing Bezel housing AR Coated Glass, in the middle is the light module. The reflector in light module is changeable and so is the LED itself.
