I have a Thrunite T1 and a Thrunite Neutron 2C…and I agree, I love the ramping UI. I can get exactly the amount of light I need for the situation at hand. I don’t have the TH20, but I have been looking at it closely.

bmengineer - Thank you. Those runtimes coupled with the quick attachment headband really makes me want one of these badly. I like going back and forth between using my light as a headlamp or a handheld, and that set up seems ideal.
