A few months ago I bought a 200mw blu ray laser and it has worked great until recently. Now when you press the button to turn it on, it simply doesn't. I can get it to flicker quickly and if I am real lucky I can get it to stay on if I apply just the right amound ot presure but it is very...

This is a review of the LZCS 200mw 405nm laser from Lazerer. LZCS - 405nm 200mW Focusable Violet Laser Pointer Ordering/Shipping I ordered the LZCS 200mw 405nm laser, the power certificate, and a 18650 lithium ion battery. This came out to 99.98 USD. The laser itself was 80 something. At...

I have been trying to buy a lenspen to clean my laser but I have been finding it difficult to tell which can fit into the tiny aperture hole and actually reach the lens. Can someone recommend me a lenspen that you are sure is able to do this? I would prefer to keep it under $15.

I recently bought a LZCS 532nm 50mw laser from Lazerer. After a few days passed I noticed that quite a bit of scatter was now visable around the dot. It was not like this before. I tried blowing on it but that didn't help. Then I tired using twisted up kleenex and then toilet paper to no avail...

I recently purchased a laser from Lazerer and I also ordered an Ultrafire 18650 battery (3000 mAh) and a charger along with it. I have read about how lithium ion batteries can explode if not handled correctly. I am worried because the charger only cost $3 and I want to be sure it is safe. Here...

What are the capabilities of a 50mw green laser? What safety precautions should I take when using it? I already own a 20mw but I want one that is more obvious in sunlight. should I use goggles when looking at the dot up close? Any feedback would be greatly appreciated :)

How do I replace the diode of a 5mw 405nm laser pen? I've always had an interest in lasers but I have never taken one apart. Right now from what I understand the window in my diode is slipping and causing it to become dim and unfocused. I can usually get it to work after much fiddling but it is...

I recently bought a 5mw 405nm laser from them for $55. The laser arrived and it worked fine although I noticed the label was wrong (it said 532nm 10mw). Then after about 2 week something in the diode went wrong and now it randomly becomes unfocused and incredibly dim. Have any of you bought from...

Ello I'm from Indiana in the USA. Ive just recently gotten into lasers and I have a 5mw red one, a 5mw 532nm green one, a 20mw 532nm green one, and a 5mw 405nm blue/violet one. I came here for help and to learn more about lasers!:D

I bought a 5mw 405nm laser for $55 and for the first 2 weeks it worked fine. Then one day I turned it on and I could barley even see the dot. Then I shook it a little bit and it went it went back to normal power. Its been switching back and forth between powers for a few days now. Any ideas of...
