I have a new Chinese UltraFire HWA/WYS XML-T6 LED flashlight with a cheap plastic dome-shaped focusable lens. I searched through the forums, but can't find any reference to this light and replacing its lens with a glass one. When I remove the lens to simulate a plain flat glass lens, the beam is just too dispersed regardless of how I move the sliding focus sleeve fore and aft. Anyone know if a GLASS dome-shaped replacement lens is available for this light? It's a decent light, it's just that the plastic lens is nasty.
