meaning

There are two kinds of light gathering methods for the lamp holder of LED flashlight, one is the light gathering cup, and the other is the convex lens. The condense cup has better condense effect, less light loss and light weight, and can tightly seal that lamp cap part to improve the waterproof effect. The fly in the ointment is that the light spot is not adjustable, so the illumination area near it is very small when it is used. The biggest advantage of convex lens is that the spot size is infinitely adjustable, but it is difficult to achieve good waterproof performance, so it is generally used by outdoor sports enthusiasts.
