I know this is an old thread, but I finally purchased a proper LPM recently, a Kenometer.
First thing I did was the 3.0V vs. 3.6V battery test in my DX200 Red Dilda.
Popped in my 3.0V green batteries from DX. The laser settled in at a measly 157mW. No wonder why many folks lambasted this laser. This is far less than 200mW as advertised.
I took out the 3.0V cells and put in the 3.6V cells. I fired the laser and watched the numbers go up, 180mW...190mW...200mW. Astonishingly, the laser measured at an awesome 237mW! Now THAT'S more like it!
Further testing with freshly charged 3.6V cells showed stable outputs as high as 251mW. Since it's not current regulated, the output decays slowly as the batteries drain. It's still excellent performance for such an inexpensive laser. And the option to use lower-voltage cells means long duty cycles for long burns or general pointing.
