The lamp is really bright - too bright for road transport. (Unless you want entgenkommende pedestrian force on the knee) The light field is homogeneous. Clearly noticeable heat generation at the front. With appropriate 18650 Li-ion batteries, which must be purchased separately operate. Unfortunately, my continuous operation is something blown at full capacity in the battery case after about 10 minutes. I noticed it only by the odor and could still remove the batteries in good time. Cover by braised, switch defective batteries fortunately still intact. This quality is not recommended. Reimbursement fortunately easily.
