It is not strange that laser pen can be used as flashlight. If you shine a green laser pen in a dark room, believe me you will be able to see each and everything clearly. The green beam can be seen clearly even if the beam far away. If you think that you cannot be caught by people that from where the beam is coming, you are at mistake. The beam will clearly indicate that from it is coming. I tried once by shinning it towards the sky, and results were amazing, I could see beam clearly crossing the clouds.
Certainly ,not all laser pen' beam can be seen through the clouds.In general,green lasers can be used in pointer sky because the power is higher than red lasers.If you want to burn things,pop balloons, light cigarettes, and light matches you will need a much more powerful laser,the one you have could maybe hurt your eye if you point it at your eye on purpose or someone else.So,when you are taking this high power lasers ,you should very clearly.
A high power green lasers is very helpful, but at the same time it can be dangerous, as looking directly into the laser will cause grave blindness. Great care must be taken into consideration as well as making sure that the person uses this green laser pointer carefully at all costs and time.
Why so many wholesale lasers in the market although this items exist so big risk? As long as we used then properly,they will give us a big favor.The common lasers on the market are red laser pen,green lasers,and blue lasers.If you just want to used it in teaching ,a <a target="_new" rel="nofollow" href="http://www.enwholesale.com/red-lasers.html<br">">red laser pointer is Ok,because the power is not so strong and the price is cheaper than green laser pointer and blue laser pointer.
If you want to applied it in astronomy.Green laser pointer is better.It different from red lasers,the output brightness is ten times higher.At night,once you put your green laser pointer in the sky,a bright green beam will appear.Astronomer use it to point stars,so it is also called "Pointer pen".
Blue laser pointer is also a big danger.You should be very carefully when using it.Certainly,the technology of blue laser is more advanced,just some experts know how to operate it.So,the demand is higher for those player who want to use blue lasers.
