I measured batteries after full discharge in laser with voltmeter. First battery has 1.6V(fully discharged) and the second has 3.3V(fully charged). I have 4xCR2 so I can use it three times then I have to charge it. It is really true. Using: First time: battery 1 and 2 Second time: battery 3 and...

See my 200mW red and green laser comparison http://www.youtube.com/watch?v=TWZVwaeUMck

I maked great upgrade! It is big glass expanding lens and big glass colimating lens placet directly to focusing head. The issue is I can light match in 2,5 meters instead of 70 centimeters. The dot is 4-5mm in diameter at 10 meters distance. So that means, the focusing is three times better. See...

I maked some interesting images: DX 200mW beam size DX 200mW dot size DX 200mW power output graph

This laser has the best rate power:pice. Recomended!!! :D

Re: New to lasers, want to increase the power of m I destroyed everyone laser which I want to incerase power. So buy better or be very careful.

Specification says 30mW but there is many many points on the wall and everyone has around 0.2mW :D

Mine starts on 35mW and in 5 seconds drops to 20-25mW. It cant burn black stuff :(

Very cool. I want to see it live. No, I want to do it. ;D

I done it too. All you need is rubber grips or rubber glovers and muscles ;) You can clean dust inside.

Yes, at 10 m distance the smallest dot possible is 15 mm(for my laser). I have also 200mW red from DX that is many times better in focusing. With 200mW red I can light match at 3 m distance but wiht this 200mW green max 70 cm. Plastic lens isnt good. I tried to disassemble focusing head to put...

-In the best conditions, dot has 15mm in diameter at 10 meters distance. It is 1,5mRad. -I have a true 30mW lasere from DX and I disassembled it and change plastic to glass lens. Now my 30mW has 0.5mRad. -If I compare it in dark, 30mW(0.5mRad) laser is shining much far than 200mW(1.5mRad)...

Everyone here know that the biggest problem of this laser is plastic lens. Beam has a very big mRad. Any idea how to solve this problem? Change plastic lens to glass lens?

DX 200 is now available ;)
