I have the diffuser lense installed.. Used the light for working on my car and other stuff after dark. It's a great head lamp. I usually have the headlamp on and a couple other flashlights with me if I'm working on something at night... works great with my XTAR 3100 18650 or Trustfire 2600- both protected.
