    The science of laser eye injury?

    I figured while I was here, I may as well ask if someone could explain the science of laser eye injury? The Googler only returns generic answers like "Yes, it can cause eye injury" but it doesn't go into the science of how? Also, is the science exactly (or nearly exactly) the same for say ...

    After a 2 yr break - returning to say thank you

    I'm not going to re-hash my story as I really didn't enjoy the first go round of being ridiculed - (I deserved it) and I got off to a very rocky start here at the LPF (rightfully so) ... But I stuck with it and I was rewarded with some very good info and eventually my desire to do what I set...

    Update on my "start a brush pile fire" laser project.

    Since burning myself up in March - ish by using one of those new "safety" USA government mandated plastic gasoline 5 gallon jugs <smfh> and having 6 weeks - ish to lay in bed and heal and think about it. I was finally able to make my idea of igniting a brush fire from a safe distance with a...

    Looking for cheap tri-pod ideas to hold gatling style blue laser.

    I know that might be a dumb question but I am looking for a small , compact , tripod type stand that will hold my gatling style laser steady. Home brew / redneck ideas are perfectly acceptable and encouraged. Commercial (cheap) stuff is also welcomed. I'm lost in this area but I see people...

    How long will 2x 16340's batteries @700mAh each produce a good beam before power drops off?

    I've gathered it's not a very good idea to turn on your laser and just leave it on from a full charge until the batteries are completely drained because of heat issues. - But in theory, I'm wondering how long 2x 16340's batts fully charged and turn the laser on - how long will the laser beam...

    Brand Spanking New / Never charged / Never used 4 x VC IMR 18350 BATTERIES 1100mAh 3.7v

    I just received them today from Ebay and unfortunately they do not fit inside my gatlin style blue laser housing. They are just a little bit too big around. Again, Brand new, never used. I got 4 of them. Would be willing to trade str8 up for 4 Efest 16340 button tops @700mAh. I ordered 2 of...

    Yet another noob question about batteries and chargers

    I have a slight touch of OCD (so I'm sorry I'm making a not difficult issue / difficult) I am in North America, North Carolina to be exact. What is the best place for me to order 16340 batteries? (Not brand, *PLACE*) I'd like Efest batts as someone else told me they were the best. 2) Do I...

    Replacement battery questions.

    Howdy. I got the el cheapo "gatlin" style blue laser off Amazon. It came with 4 "+J 16340 1500mAh batteries. (only 2 are used at one time) It's becoming obvious those batteries are hot garbage and I am looking to replace them with better batteries. My question is - I see some on Amazon...

    Brand New, Noob. Part II - lets escalate.

    So right away I have to thank Redcowboy because he took the time to help me visualize "safety" - if that makes sense. He was able to verbalize context. I'm 100% confident now with this Amazon blue laser. It will light a match on fire from 5 ft away pretty fast. <side note - that still terrifies...

    Brand new, noob, *TRYING MY BEST TO BE RESPONSIBLE*

    Long story short: I live way out in the country and I want a laser that will "spark" a fire from about 10 ft away.......... If I have to / need to use "flash paper" in order to accomplish this - fine. I'm perfectly fine with that. My main concern is "safety" for not only myself but for any...
