Great light output as early as the 2nd stage (3). Even while running comfortable to wear - of course the headband promotes welding tendency. Possibly a terry cloth belt in between take or attach the lamp right on the belt; it is solved by the split retaining clip quickly by the headband and threaded elsewhere. The minimum head size can be adjusted to 37cm. The tilt can be adjusted with stable latching, batteries of a brand manufacturer are included in the price. Note: To turn requires a "double click", each click represents a further step brighter. Strong buy recommendation!
