5mw 650nm red Customers Reviews

  • Laser review

    posted by AlexandreFr

    Good build quality, I like it.
    Feels nice and heavy.
    Grip is nice from some sort of rubber-feeling paint.
    If you light the red laser and and run the light accross a plane surface you can see that there is a continuous line.
    On the other hand if you do the same with the green laser, it apears as a dotted line.
    this makes me think that the Green laser has a stonger peak power but has an average power that is lowered this way.
    Green is still way brighter than the red.
    I would be interested if someoine came in with some sort of simple hack to bypass the power limitting feature and alow to use the green laser at its maximum power. (mabe over 5mW)
  • The diodes are just as normal red laser diodes. Good price for what you get

    Those diodes are good primarily for checking red laser diode drivers before installing an expensive red laser diode. I'm only a begginer in building lasers so I can say that it helped me to build some 100mW lasers and also some 200mW lasers.The price is relatively low for what you get.
    You have nothing to lose if you buy it, the price is very low so you can afford to buy this and test it yourself.
    I very recommend for begginer laser builders to buy those diodes for learning how to build lasers.
  • Accurately made thing.

    Complete set. In total that is necessary is available. Good fine tuning.It is established on a pneumatic gun. Fixed on a trunk weighting compound. On fastening going in a set it is possible to organize a lamp (easy to pick up the size) anything ???????? it is not necessary.
    there is no fastening "larkspur"
    about the spent money I am not sorry. I recommend.
  • A Ok Laser Pen

    posted by AFGSM

    Todas as quatro funções funcionam normalmente. O laser parece realmente alcançar 500 metros. E vem com mais quatro figuras, além do ponto laser normal, o que para mim é desnecessário, mas para crianças pode ser legal. A lanterna é relativamente brilhante. E a caneta, tinta preta, funciona normalmente. (All four functions work normally.)
    A qualidade não é das melhores, porem por esse preço será difícil achar alguma coisa melhor. Sendo assim se você precisa de uma caneta laser barata, essa pode ser uma boa opção. (Quality is not the best, however for this price is hard to find anything better. So if you need a cheap laser pen, this can be a good option.)
    Ok.
  • Great value

    Sturdy design, easy grip, the ability to have a key to use as a safety switch is a useful feature when you don't want kids or anyone else to turn it on. Another good feature is the fact that you can use CR123A batteries as well as 18650 and if you pull a bit to lengthen the spring you can use CR2 as well. You also have a bit more than 5mw. As I have no way of measuring it I would say it's at least 30mw maybe 50mw.
    Mine came with no keys but I've bought the green one as well which had two keys as it should.My battery was used, so beware.
    Decent price and quality. So Yes buy with confidence
