head lamp ,lens zoom,3 files,XML-T6 860lumens 1.lens zoom headlight 2.high led headlight 3.2*18650 battery YEZL:H5 HEAD LIGHT1 Weight: 500 g (including gift box)2, the luminous body using the latest U.S. high-power LED T6 maximum brightness of 860 lumens.3, the use of imported high-quality aircraft aluminum, precision machining CNC CNC machine, exquisite workmanship, anodizing surface treatment.Aluminum reflector cup, the reflection efficiency of the concentrating effect is perfect.2, the circuit uses a well-designed constant current circuit.3 files dimming: high - low - flash explosionA. High light, Current: 2800MA, brightness 860LMB. low light, Current: 1000MA, brightness 200LMC. The flash explosion, Current: 2800MA, brightness 860LMShift: three-mode switch, the first light, the second low-light, three Baoshan, followed by cycle.Battery: design the parallel combination of the two 18650 batteries, even if a battery has no electricity, headlights work as usual, highlight, can work for 2-3 hours, low light can work continuously for 10 hours.Tips: Whether it is that section of the headlights, as long as the battery is a parallel design, it is recommended to use the battery with protection circuit, or two battery voltage is not the same, it is likely to cause one of the low voltage battery over-discharge, lead battery scrap .
