Because the lenses are so thick, only the color of the bulb inside can be seen from the outside. When I shine light on paper or on my hand, even the reflected light is not direct light, it is also very harsh, and powerful, just looking at the reflected light, the eyes can not focus for a moment. Even when used in the dark, the brightness is stable from a few meters away and will not disturb you at all. For this size and single battery, the brightness is amazing and you can feel the high quality of the condenser. I remember red light being the only color available before. But now you can choose from the different colors of lasers available on the market, including blue, green, purple, and yellow. These colors have the same power consumption, but different outputs in terms of visibility and brilliance.
If a pen is used, it will be put in a nice box. I carefully opened the box, which was surrounded by four replaceable heads and two laser Pointers that could be replaced with spare batteries if they got stuck. The parts written only with the laser pointer felt heavy and silvery black to the touch. And an ordinary super powerful 500mW green laser pointer as long as the pen is limited, it's much thicker than the pen. Many useful green laser pointer are powerful, but more than you do...... More searchlights, Pointers can give you a teacher who can even dive if it really helps!
