    You should definitely try this LED in a light that has halfway decent heatsinking potential, such as a D maglite, where you can put the LED on a large Aluminum Heatsink (and maybe use a maglite with finned heads.

    Or, you could get a 6D maglite and use one IMR 26650, and fill the rest of it with ice. However, there could be some issues with shorts...

    What is the Vf of the LED? I thought these larger high output LEDs tended to need 20+ volts, since they were never intended for portable lighting sources.

    So if I'm understanding this correctly now, it's not a regulator at all. It's a pwm dimmer like TaskLED's popular D2Flex. Essentially a direct drive circuit at full power minus whatever minimal voltage drop there is from the MOSFET's internal resistance or RDS(on) value of 6.6 m-ohm. I already have a couple of AW's IMR 18650's. I'll have to get an SF-15 and an SSR-90 to do a little experimenting.

    step one remove the p7star , put the ssr-90 star and substitute the wires by copper wires



    step two repair the springs we need very very low resistence and the springs have high resistence:
    springs resistence +internal battery resistence+ swich resistence + mosfet internal resistence+wires resistence + body resistence+ contacts resistence must be < 4.2-3.6v(vled)/9 amp= 0.066 ohm
    the total resitence must be < 66 mohm if we want 9 amp






    step three feels the power

    this mod is only to obtain the max luminous power in pocket size when I want, and in mid mode its very brilliant and efficient, around 400 lumens in mid mode

    I am going to also buy another ssr-90 for make a large flashlight

    v led at 8-8.2 amp is around 3.56v with battery full charged

    That's a horrible heat sink for a P7 and even worse for the SST-90 at full power.

    Output drops significantly at high junction temperatures. I doubt you're getting more than 1000 lumens OTF. Anyone have a extra integrating sphere?

    according to my measurements with luxometer in a closed room I obtain 1350-1400 true lumens.

    they are not 2250 lumens but its ok for me for this size

    in high mode is equal of powerful than my hid 24w(1400 true lumens) and more powerful than 2 flashlights p7 bin D together (1 p7 bin D flashlight @ 4amp =600-700 true lumens)

    in mid mode I obtain 350-400 lumens with really high efficiency

    I never have seen a power mosfet transistor as large as this in another driver of flashlight

    you can buy a large power mosfet chanel N 70amp for 1$ and to control it with another low-power driver pwm

    What is your reference light? None of the lights in your sig qualify for being a reference. They're all horribly overdriven (by the way, you'll probably get more light out of that RC-G2 if you lower the drive current to about 1A...) and have the same problems as this light. I believe you said you own a Jetbeam, but super throwers tend to not so good for ceiling bounce/lightbox measurements. Either way, lightbox/ceiling bounce is really not that accurate in the first place.

    The AMC7135 multimode drivers are PWM. Just desolder the 7135 chips and toss in an $6, slightly overkill, 240A, logic level MOSFET http://search.digikey.com/scripts/Dk...034TRL7PPCT-ND

    At 10A, you'll only be dissipating 140mW of heat!

    its very hard to obtain more of 8,6 amp with the driver,i need to reduce the total resistance to obtain 9 amps, yesterday improving all the points of electric contact but only obtain 8,6 amps

    I am thinking for my next sst-90 flashlight about put it direct drived with two ways(hi ,mid ,off) with resistance in low mode, direct drived obtain easily 10,5 amps and many more lux than with the circuit (I have also taken it lux measurements direct drived) .the efficiency will be smaller in mid mode but I prefer this way and obtain more than 9 amp

    obtain the max luminous power in the smallest size its the only thing matters for me for this mods flaslights

    Hello Moviles,
    I am newbie in this forum, best respects for your work- flashlight as small as it can be- and max lumens! Ordered yesterday on Dx the MTE, ordered 3 days ago SST-90 with & without star from german dealer on stock(!) to rebuild your ideas- and in my opinion all the bad posts according to your work are the same as those, who will never accept, that a SSC P7 will never be driven under full power in a 12,00 cm host without a heatsink, cooled by something like the ice age or anything else like armageddon, ... poooof... :-). By the way i am building a 5x SSC P7 in an Ultrafire wf-500 host, direkt driven by 5x 18650, sunday i´ll push the button- if i am still alive, i´ll post a picture...
    Moviles- thanks for your ideas and best regards from germany,
    Steffen

    Hello, I got this adress to order from someone from Avnet in Germany:
    http://www.amu-electronics.com/9.html
    I ordered only one single SSR-90-W65S-R11-GK100 and SST-90-W65S-R11-GK100, I ordered wednesday and hope ill receive them on monday- price you have to request, cause he offered me a special for both, but expect something under 30,00€/ per piece.

    I seriously doubt he's getting very good performance at all, and the other thread was mostly about safety regarding drawing 3+ amps from a LiCoO2 14500 cell. as I said, lucky he's using a IMR in this mod.

    safety is still a top priority... It isn't worth the risk of a exploding Li-ion cell just because you wanted the quick thrill of an uber bright light for a few seconds.

    I agree with you here, though. . but, with the current public, it doesnt take too many lumens for someone to say that..

    movilles, can you do a runtime with your luxmeter? turn the light on and record lux values every 30seconds or so?

    Your transistor selection looks WAY off!

    The cmt70n03 is a 1-3v threshold. You need significantly MORE voltage than the threshold to turn it on all the way, and turn it on quickly. Failure to do either will result in lots and lots of heat.

    Your schematic shows a diode protecting the PIC, so even assuming it's a Schottky, that's 3.9v-2.2v Vgs. You need a FAR lower Vth than this! This is at high risk of current going into saturation region, which will probably let the magic smoke leak out.

    Also the capacitance is a huge issue. The heat generated during switching will typically be much greater than that generated due to I^2*Rds-on heating.

    In fact, bigger current ratings typically mean proportionally higher capacitance (given similar construction), and thus the part actually can handle LESS current during switching with a modest gate drive like a PIC than one with a lower rating.

    Another thing, the current ratings across different packages is funny. See the rating is based on how much heat it'll take to damage the junction. Bigger packages get higher ratings not because they've got lower resistance, but because of greater dissipation. Consequently, they're often higher rds-on and less efficient than the same current rating in a much smaller package.

    Another significant factor, the ripple rating of the input cap. Tantalums typically have "high" ripple current rating for their size, but in these tiny caps it's still pretty small. I've had tantalums several times larger than these in flashlight drivers that can only handle like 200mA PWM'ed off a lithium cell before overheating. I found better ones which can handle more, but the tech's pushing it. Ceramic MLCC typically has MUCH lower ESR, and there are some darn high capacitance ones in tiny packages now.

    What kind of run times and lumen output do you get in medium mode? How hot does it get in this mode?

    How did you mod the springs? Can't tell what those are from the pics.

    in mid mode around 2-2.5hours, around 350 lumens with battery at 4.23v,the max temperature its only around 38 C (mid mode)... but now I maked it direct drived and have only the high mode because no way to get more than 8.6 amp with circuit(its necessary a really very very very low resistance)

    the springs: its necessary repair the sprigs because springs have high resistance and I need very very high pressure on the electric contacts to obtain great current and output

    great area of contact is necessary too for dont destroy the bottom of the battery with the high pressure necessary

    ok,its all true
    but no room into the drop-in for boost circuit for the pic , since 1 week I have it direct drive because its really hard get high currents with the aw18650 imr and only 4.23v

    Iwill make it with 3 modes switch high (dd) mid (resistor) and off

    since around 2 weeks I have it with SKU 15739 switch ,2 mode high direct drived and low with resistor

    10 amp in high mode and more output

    left mte sf15 with ssr-90 right aurora SKU 15739 with tiablo collimator and ez900

    I want buy more SSR-90 for make more custom flashlights but no way to buy, no stock everywhere

    I prefer the high bin SSR-90-W65S-R11-GN100 but the cheap SSR-90-W65S-R11-GK100 low bin its ok too

    edit
    :the best its the GN102

    Can you mod a flashlight, using sst 90 that can give a +-100% throw more than 2 hours ?...and if you can...can you email me at mohdsharir@yahoo.com the price that you wanna quote for it...including shipping/ batteries/ charger to Malaysia..thanks
