China Wholesale 200mw Strong Green Laser Burning Pointer with Key

Burning.........., Friday 09 July, 2010
This Laser is amazing in the dark. But my laser can never light a match. Have tryed so many times, but it wont light the match........It says it can, so why can't it? The battery is full charged........?

May be the laser you bought is a adjustable one. The head of the laser can be adjust, you can turn the lid to the tightness of focus, the more tightly the lid switched, the more intensive the light will be. Then you can put the light armed to the head of a match then it will be lighted. And you'd better do not keep pressing on the laser button for a long time, otherwise the laser will be burned by itself. You'd better just press the button for 1 to 2 seconds then release then press, you ca repeat this action to keep it work but don't keep pressing the button.

200mw yotang laser power, Sunday 25 April, 2010
please note: in my first review I said that my 200mw Yotang laser had 124mw ( really 124.9mw ) of power output. in my second review , about buying the Laser Bee, I said the first Yotang ( I bought 2 of them ) had 192.5mw output. I made a mistake in my first review by not factoring in the Laser Bee wavelength power correction factor ( found here http://www.bauer-electron.com/opm/hlpm.pdf ) of X 1.54 for the 532nm green wavelength. the proper , real, power output for the first laser I bought was actually 192.5mw output ! sorry for the mistake, and these are great lasers !

measuring the power output of this laser, Sunday 25 April, 2010

I bought a Laser Bee ;laser power meter to check the power of this laser. I have bought two of these lasers and have been VERY happy with them but wanted to know their actual power output. the first one I bought ( which I have given to a friend ) measures 192.5mw true power output in the 532 green wavelength. the 2nd , most recent , one I bought and the one I currently own , measures 203.28mw true power output in the 532 green wavelength. BOTH of these lasers have enormous IR power output as well, but the Laser Bee is blind in the IR. my latest Yotang literally bursts matches into flames , instantly. red , white or black, it fires them all. you can see my latest laser cut a roll of black tape in half on Youtube http://www.youtube.com/watch?v=a56jbPHN_-A .

I have bought my 2nd one of these great 200mw lasers and I have made two Youtube videos of them. see them insta-pop balloons and insta-light matches
here http://www.youtube.com/watch?v=_baZISEJfMc and here http://www.youtube.com/watch?v=oboToM6bxGY or search " Yotang 200mw " on Youtube.
Both my lasers have been impressive in quality and power output. very satisfying to own and use and those safety features ( key switch and beam shutter ) and the battery and charger ( that come with it ) add to the experience.

I bought this laser and was impressed with it's high quality construction. my laser measured 124mw output in the 532 wavelength green but had a LOT of additional output in the IR wavelength. probably the total light energy output was well in excess of 200mw. my laser easily lit multiple matches in a row nearly instantly once it got started ( takes a moment to build up the beam power ) and would instantly pop a balloon across the room when focused on the balloon. the safety shutter and the key lock in the end of the barrel were excellent and handy to keep those busy little ( children's ) hands away from hurting themselves. this laser's ability to focus the beam up close or far away sets it apart from ordinary laser pointers , as does the hefty rechargeable battery and charger. I highly recommend this laser based on my personal experience with the one they sent me. the power from this laser is substantial, I recommend closely following laser safety handling precautions and using laser sa
