Blue lasers are actually the same type of lasers that are used in Blu-ray technology. Although it is rarely prefered to the green and red ones, it could be used for what others do, which also reflects the individual unique aesthetic taste. As far as presentation pointers go, it can be a nice change of pace to use a blue laser pointer, but much more powerful blue lasers are also available. However it comes down to all other uses such as pinpointing something on the large screen or on the blackboard.
It is very bright in daylight! The product meets my needs at a good price.
I bought three and they are all perfect, with very good focused beams. The best laser pointer I have used so far.
My laser arrived yesterday.I tested the power,it's not 2000mw as stated on the website.However,it
wow this one is amazing burns on demand.
Me llegó aquí en México exactamente un mes, lo pedí el 17 de julio y llegó el 17 de agosto. Les diré las ventejas y desventajas. Ventajas: Obvio es un laser más potente que los que consigues en el tianguis :v La lente de los puntitos se ve muy bien, tiene una llave de seguridad para que los niños no jueguen con el y tiene un buen material, es de metal :) Desventajas: Intenté encender un fósforo (obvio enfoqué la lente) y no pude quemarla, solo pude tronar los globos y una bolsa negra. Y la batería no le dura mucho (como un día) ya que el laser consume mucha energía. Pd: La batería tarda en cargarse unas 2 horas y media.
I love my green laser pen light it works awesome just wish my purple one would get here.
Seller shipped unit in a timely manner. Unit arrived without any damage. I was disappointed to open the package and find absolutely no instructions or documentation. My unit shipped with the battery installed backwards, but I didn't know that the battery must be installed exactly the opposite of every flashlight that I've ever owned. Again, no instructions included with item. Tried charging the battery, but charger was flashing red. Most chargers this means the battery is no good. Apparently flashing red is a normal condition with this charger. Did I mention there were no instructions? Finally the light on the battery charger turned solid green, meaning that the battery was charged. I reversed the battery so the positive end is at the cap where the key is inserted and the laser worked. An unnecessarily frustrating experience which could have been completely avoided with a simple set of instructions.
The first laser pen I paid for got lost in transit,the seller was so kind as to resend a new one for me.The second package just arrived,though I waited for a long time,but it is worthwhile.What I am going to focus on here is that this beautiful silver appearance and blue color beam laser pointer will definitely give you a big surprise.Super bright and powerful,which is much better than I expected.
Blue Laser Pointers
Green Laser Pointers
Green laser pointers are now the world's most popular laser pointers, because the green light than red light 6 times more than red light beam significantly, while the price is much cheaper than the blue and yellow, green laser pointer is simply more powerful than red laser pen. Of course, this also means that green lasers are potentially more dangerous than red lasers. When operating this type of laser, it is important not to point it into anyone's eyes or to point it up in the sky towards any airplanes. It is probably not as much preferred lasers as an astronomy laser pointer, because brighter colors would make an object more visible in the sky.
Red Laser Pointers
Red laser pointers are by far the most popular and least expensive type of laser pointer. This is because the wavelength of the red color can be manufactured more easily than that of the other colors in the spectrum, red laser is also the only color that is available in the smallest size of laser pointers. Do remember that red laser light is powerful when it hits a certain object and converges into a point.
