Because it doesn't have a box, it's 500 yen off the regular price. This is a 20W super-bright zoomable light from Alonefire. It's a full set with a lithium-ion rechargeable battery. ⭕️ The lithium-ion rechargeable battery is a new Panasonic 18650. ⭕️ I performed a 3-minute irradiation test outdoors. This is a 18650 lithium-ion rechargeable battery set. You can charge it directly on the main unit, so you don't need a charger if you have a smartphone. This type is usually around 10W, but this one is 20W. Therefore, the irradiation distance is about 500m to 600m. The light distribution is also different; usually, the shape of the square LED chip is directly projected, but this one has a beautiful circular spot. This special price is for postal delivery.
