    Question about my new LaserBTB

    My HL 532nm 100mW finally arrived, much to my disappointment was only 3/4" shorter than my HL 520nm 100mW. I bought this laser solely because it had the same interface as its big brother and was hoping to be at least 1.5" smaller. Anyway, no biggie. Too long, can't carry it for my intended...

    No short 532s that runs 2AAA?

    Hello, tried searching but came up empty. Where could I source 532nm laser pointers ranging from 20-50mW that has a body length around 5 inches? Closest I have is a 5mw Lyra from LaserGlow, just a tad over 5 inches, extremely handy. My Sky laser, LaserBTB, Optoelectronic pointers are all...

    Highest Green before burning hazard

    I was just wondering...seeing that the FAQ didn't speak of this. Unlike many here who keep their lasers in the padded case just prior to use, I keep it in my pants when I'm on the go, even around the house. It is an unconditional guarantee that as long as I'm in public I'm wearing black pants...

    Questions about the Laser Glow Galileo-5

    Hi, new comer here :). I made a search for the same topic but I have not found an existing thread that explains it. Does anyone know the current consumption of the Galileo-5? It seems that CR123As are drained essentially within an hour or two of continuous use...the batteries I have tried are...
