Black Diamond Spot 400
Regulated output, a proper red mode, AAA batteries and a sensible price. The default answer.
This is the one to buy without overthinking it. Regulated output is the feature that matters most and is least advertised: an unregulated headlamp starts bright and fades continuously, so by hour three you are walking in a dim yellow pool, while a regulated one holds its output and then drops to a reserve. The red mode activating directly rather than after cycling through white is the second underrated feature -- it means you can find something in a tent without blinding the person next to you. The interface is the common complaint, and it is legitimate: the touch dimming takes practice and is awkward in gloves.
