    building new maglite into dd sscp4

    its been a while since ive visited. on black friday i got a bunch of maglites upgraded 2d and 3d mags. my question is can we build these into dd sscp4 lights like we use to with the old mags. i understand we cant take out the new led and put them into the old mag, but can we still dd something...

    How to wire 9 xp-g for direct drive?

    sure it is, and in my humble opinion, a resistor still qualifies as direct drive. maybe a regulated 7135 doesnt, but a good old fashion heat wire does.

    How to wire 9 xp-g for direct drive?

    are you sure 2 lithium ion c cells aren't just 4.2 right off the charger, cause i thought they were 3.6 or 3.7 like the 18650s. if they are 3.6 or so, i'll tell you in theory how you could dd them, although ive never done it per say. you could wire 2 in series, 4 times, with each group being...

    SST-50

    nakes results showed over twice the draw, over twice the lumens of an r2, however, only 2/3 the lux. we can only conclude that the lower lux of your light does not mean its less bright over all and a fail. just means the sst50 seems like a flood light like the 4dies, but probably without the...

    2 bad dd mag mods- what am i doing wrong?

    the led now on the 4d mag was in a 3d pulling .2 amps. i moved it up to a 4d and tested at .7 amps. just a very high vf. its dd. no resistor, variable resistor, or driver. as far as the 2d, it is the same led i believe, but different symptom so i dont just attribute it to the led. we took the 4d...

    SST-50 EDC Light 1st Run *All Shipped*

    Re: SST-50 EDC Light *1st Run Closed* please please do an 18650 run of this light either with sst50 or 90. +1 +1 3 mode, no sos strobe would be insanely awesome.

    Optimum D-size Mag for P7 on Alks?

    the 7135 simple resistors will help you keep a constant current until the batteries start direct driving the led (at the point the 1.4 amp 7135 is actually more than the almost dead alkalines can give they will no longer "resist" any current). find a chip with four of them, as they are 350 ma...

    2 bad dd mag mods- what am i doing wrong?

    i finished my 4d dd high vf led mod and it should be putting out 700ma as i tested it with 4 d's and that's what it was getting right off the bat. however the light came on, shone nice and bright with a flood of light, then went down to about the brightness of a fenix eo1, if that. also a light...

    need help 3d mag dd build weak

    thanks. keeping the same 3d body and adding a fourth d cell (nimh) to it netted me .7 amps on the multimeter and that should suffice for me. its a build for a friend and he will be using alkalines no doubt. however any further insight or advice is welcomed. for now i'm transferring everything to...

    Optimum D-size Mag for P7 on Alks?

    its a tough science picking the perfect match. i just build a high vf 3d that is only pulling .2amps whereas my low vf 3d pulls 1.3amps. im changing the high vf led to a 4d and according to my multimeter i'll then get .7 amps. that seems backwards of logic that a 4d should get less current to...

    need help 3d mag dd build weak

    so im building another build. this time a silver 3d. i've got a beautiful red 3d sitting next to it that i've got pulling 1.3 to 1.5 amps depending on when i test it, and the one im building now just looks weak and enemic, thus i pulled out the multimeter and im barely getting .2 amps. its...

    need help starting 4d resistored mag build

    since my goal is a constant 700mah, should i use one of those "smart" resistors from dx that keeps a constant current instead of limiting voltage? is 700 about what you all would recommend for a long lasting 4d alkaline build? im looking at about 170 lumens from the bulb, any idea of my runtime...

    hey guys, read my last two posts. i still need help understanding things for this build. :(

    need help starting 4d resistored mag build

    also im assuming that since i got a h bin low vf led bulb, that if i want it to be on the conservative side (500-700mah) that i would need more of a resistor than if i had an i or a j bin? do i understand the mechanics of it right? harry n, thanks for your offer of hooking me up with some...

    need help starting 4d resistored mag build

    harry n, i do believe im gonna take you up on that. but first guys, i was just at radio shack and they didn't have the ones i needed. can you help me understand what the ohms rating and the watts ratings are for. i assume the ohm is how much resistance it gives you, thereby reducing the power...

    need help starting 4d resistored mag build

    huh. i thought each led had a certain voltage that was considered its "vf" and that they varied so they binned them in categories like h(3-3.25) i(3.25-3.5) j... and so on. so the vf used in that forumula someone linked me to can vary with drive. i knew that the voltage going in varied the...

    need help starting 4d resistored mag build

    cool. the vf is 3.0-3.25 but if the drive ends up being a little higher thats ok. at what point will the d cell alkalines start becoming inefficent?

    need help starting 4d resistored mag build

    oops. not out of the water yet. someone verify my calculations. i have an h bin led, going into a 4d maglite, i want about 700mah to save alkaline batteries since the build is for a non-flashaholic, and i plan to use a 2 ohm resistor. does 2 ohm sound right and where do i buy one?
