i opened this baby up and found more than just resistors in there. I saw a capacitor, a black rectangular bar lookin thingie not an inductor (dunno, IC maybe), and some other stuff. isn't this a step up? also, i put a dummy battery into the case, a nichia white led where the krypton bi-pin bulb should have been, and tried it. the 3 led's at the top would light, but not the single led where the incandescent bulb should've been. yes, i know i hooked up the led with the correct sides because i tried it without a dummy battery and it worked. Why put a step-up into a light which already has 4.5 volts? someone with a trident please open theirs up and see? you have to remove the reflector cup and led housing and unscrew the two screws. this is assuming, though, that the cyclops lighting solutions headlamp is the exact same as the stremlight Trident. looked at pictures of the trident, and the funny little design on the battery case cap is the exact same. if someone else who knows about circuits has the cyclops light, please try also.
