    Hehe. It's definitely fake!

    I don't believe you can buy it and try it.

    200MW is a match that can be lit.

    The laser pointer technology is not yet up to 300MW.

    In fact, the standard is 200MW, and the maximum is 130-170MW, and the ** is about 400.

    The laser pointer for lighting matches is generally enough for 100MW, between 300 and 400.

    Don't look at his reputation, most of it is brushed.

    There are a lot of false reports of power, especially the 300MW one, which is only sold for 140 yuan (not to mention that the power itself is not easy to get).

    Some of them are not fake stores, but the merchants don't know much about them.

    It is recommended to go to the flashlight forum.

    200MW of continuous irradiation should be able to light a match, and 5W should be able to cut metal.

    It is almost impossible to light a match, my 100MW shines on the hand has no thermal effect at all, I estimate that I need more than a dozen W to light a match, the price will be much higher, and a few thousand yuan may not be enough.

    The above ** is a little low, and the power may be false. 95 yuan is only enough to buy 50.

    If it is said that the ** of the green laser lz is too low, especially the few low ones with high power, go to the flashlight forum.

    Learn to learn in the laser section and buy it from a recognized merchant of the altar friends.

    Let's talk nonsense, how to find 50MW, you have to go up to 100, 75 can't be believed at all, it's not a quality problem, it's not enough wattage, lighting a match 500MW should be able to kill in seconds, 300MW should be OK.

    300MW of 140? It's so unbelievable that lz won't write an extra 0.

    Although some laser pointers are similar in terms of use, the effect is not the same, and there will be deviations because of other metaphorical regional sales or something, generally dozens of yuan! You will see that there is **, and there is a "Dandan Store 886" on it, and you can also consult it.

    Laser pointers with different functions, ** are also different, go to the official website of Shanghai Nuowei Electronics to learn about it, I think there are what you want to choose, red light, green light have. Nuowei brand is good.

    This is a model of a copycat laser. Or it can't be said that the copycat model, that is, there is no brand of laser that will use this shared model.

    The power of this laser pointer is generally 10-30MW, and there are also up to 50MW, which is rare.

    However, many businesses will mark the power as very large, such as 5000MW, or 10000MW, which is very bold.

    In addition, beginner users who don't know about lasers will feel that the power is so large, and it is cheap. Will take it seriously.

    The 30MW one is also enough to make a finger pen, and the beam is obvious at night.

    Look at the air quality. Generally 10-30MW are available.

    Green light can light cigarettes online shopping 65, shipping is not included, 200MW power, 4 meters to kill dark balloons.

    The laser pointer pen must not be ignited, and the energy is too low.

    Other questions are unclear.

    90 yuan, 5-80MW for pen modeling.

    However, the 80MW full power only earns about 10 yuan.

    5-25MW can earn dozens.

    If the 90 yuan laser flashlight is modeled, it is about 30MW. There is a JD850 model.

    The above beam effects can reach a range of 1000-2000 meters.

    Green lasers below 50 MW can be seen in the dark at night, and in urban areas where light damage is obvious, it is slightly insufficient to use it for star.

    Do not use high-power, within 20-100MW is fine.

    Don't keep lighting for too long, more than 5 minutes will burn the lamp, generally a few seconds is fine.

    The finger pen is a kind of laser pointer, which is a semiconductor laser, which belongs to a kind of LED; An optical lens is usually added to the front for focusing; Lasers are harmful to people because of their concentrated energy, and they cannot be directed at the human body, especially the eyes, which have the risk of blindness.

    When not in use, take care to remove the battery.

    1: A laser pointer that can ignite paper, and the current test of Nuoqing NQ-409 blue light can.

    In other words, as long as the real power of your laser pointer is enough for 2500MW, it can ignite the paper.

    2: According to the 303 model you sent, the actual power should be relatively small, if less than 100 yuan, or thirty or fifty yuan, you can light a match, the actual power is 50-80MW, if you can't light a match, the actual power is less than 50MW

    3: How much is the difference between 50MW and 2500MW, you can see for yourself.
