Feng Laser Head Copper 650nm 9mm 3V 50mW Laser Cross Diode Module Red VN Laser

If the head needs to be lit for long periods of time, please increase current limig resistance appropriately 1. Never look into the eyes of yourself or others at any time. Even when turned off, it may be turned on by mistake. 2. It is impossible to irradiate any reflective or smooth surface. It has excellent reflectance. It will reflect when irradiated on reflective surfaces. If it occurs irradiation of people's eyes, it may cause injury. 3. It is not a toy and should not be used by children, those with incomplete intelligence and those who do not understand the features of the features. In this case it is very easy to injure. 4. Wear special glasses when using them, especially invisible ones. 5. Failing to provide lighting on vehicles, aircraft and other manned vehicles. 6. To pay attention to safety of the circuit to prevent the process of burning or short-bursting of circuit which is removed by other persons. The particularity of the emission principle and the generation process determines that there are features that ordinary light does not have: three good (good monochromism, good coherence, and good orientation) and one high (high brightness).
