    headlamp emitter

    yes backside of lamp. not much to it.. emitter mounted on the opposite side and a zoomable head with maginfier lens. is it a type of Cree? its sold as a cree. the square beam has a line seperating i/4 of the square and a small square corner of that square is missing. the photo is not very good.

    epoxy

    would harborfreight.com's 5 minute super stregth epoxy be suitable for attaching Luxeon leds to a heatsink. i dont want to spend double or triple that if i dont have to. my light projects are way over budget now and overkill it seems since i got a couple luxeon flashlights at Lowes for $2.50...

    Li-Ion safety cap DIY

    i still want to add a heat alarm too. can be very simple...no? or just a thermal fuse. edit: okay i guess epoxy may be drastic.. this super gooey double sided foam tape they glued this stuff in with might be a good idea tho.

    Li-Ion safety cap DIY

    so...seriously.. will the luxeon stop current at below 2.8v? is there a simple regulator that will shutdown at 2.8v? i can install protection at the charger if it doesnt have it. with a epoxy'd cap on + nobody gonna be mis-charging it unless its me anyway.

    Li-Ion safety cap DIY

    so there isnt a good diode for cutting off current at 3v nevermind..that doesnt add up..not enough volts. a luxeon flashlight is the only thing that makes sense here. the lux will stop current at 3v? no?
