    Default Moby Dick Trinity (3 X Ostar, 3 X Cree, 3 X Shark), beamshots added

    Hardware:

    - Fivemega FM3H head
    - FM fat tube, 120 mm extension, deep tailcap
    - 18 X AA holder 10.8 V operation, soon to be powered by LuxLuthor 12 X Emoli 18650 pack
    - (3) 1000 lumen Ostar LE UW E3B QZ
    - (3) Fraen narrow beam reflectors
    - (3) Cree XRE Q5 WG
    - (3) McR17XR
    - (3) parallel SF-V Shark drivers, each driving (1) Ostar and (1) Cree in series. One mother Shark wired to the pot, and two slaves wired to the mother
    - (3) machined aluminum SharkSinks
    - (1) 20K ohm logarithmic pot
    - Heatsink CNC milled from 3" round 6061 aluminum, improved one-piece design, 8.5 oz.
    - Custom LZ pot knob w/ trit vial indicator

    Specs:

    - Current pot-adjustable from 0 - 920 mA
    - Vf of LED strings: ~25 V @ 930 mA
    - Cells are supplying 77.5 Watts




    Pictured next to the original MD:



    Beamshots
    Camera settings for beamshots: ISO 200, F3.5, 2.5 sec, white balance to sunshine.

    Lineup and beamshots L to R:
    - Arcmania SF-V, 1000 lumen Ostar, 2 X 17670
    - Surefire M6, HOLA, M6-R pack
    - My Quinta Magmod, 5 X Q4 WH/McR17XR, Shark/pot, 3 X 17670
    - Moby Dick MDXR-9, 9 X Q5 WG, 6 X 17670, 2s3p
    - Moby Dick Trinity, 18 AA NiMH, 9s2p
    All cells fully charged.




    The beamshots were taken from my porch, as you can see it's snowing lightly which reduced throw. I aimed the lights down the driveway at the road running left to right in the distance.

    In the foreground the small tree at center is at 35', and the far bank of the pond to the right at 80'.
    To the downhill left bend of the drive it's 200', the road is 350', and across the road is a grove of trees at 450' of which some trunks are visible.

    In all the pics you can see the edge of the beam except for Trinity; her beam's too wide to capture with the focal length of 18mm. The small tree to the very right at 10' gives a good indication of beam width and spill.

    I'd like to thank to MJ and Mac for their help with parts and expertice, and DFiorentino for planting the seed in my head.

    EDIT: Shark micro sink installation

    While waiting for LuxLuthor's pack, I've been testing the light running on the 18 AA, 10.8 V holder. I found that due to thermal issues the Sharks were shutting down after 1 1/2 minutes on hi.

    The Sharks were getting hot due to the level of boost (to be somewhat alleviated by the 14.8 V pack being built), and due to the total power running through them. Wayne recommends 15 Watts max in the stock configuration, and these are pushing over 25 Watts each.

    I disassembled the light and fabricated two micro sinks for the top of each Shark from brass shapes and Romex core. The box sink with the soldered Romex epoxies to the top of the IC, and the bent leg sink to the top of the diode. Both create thermal mass and a path to the tube.



    After reassembly, I tested the light running off my power supply at 16 V, 4.8 A, and after four minutes the head got very hot, but the Sharks were still happy. I reinstalled the partially depleted 18 AA holder and ran for 5 minutes, the last of which the cells couldn't keep up and the Sharks were flickering, straining to maintain the increasing level of boost. Again the head got hot, but the Sharks were still going strong.

    Words fail me when I look at these masterful lights of yours Dennis.

    Yet another fantastic creation.

    I guess it must be outputting about 3000 - 3500 lumens at max?

    What is the beam like with the narrow Fraens?

    Does it project far or is it floody?
    Change is inevitable, except from a vending machine

    Thanks easilyled.

    The beam is still floody even with the narrow Fraens.

    It doesn't throw as well as the 9 Cree MD, but the beam is much wider with brighter spill. Definitely brighter than the Cree MD, and your guess about lumen output is as good as mine. It has a nice white tint too, makes the Crees look more green.

    Once I receive the Emoli pack from LuxLuthor, I'll take some beamshots. The 18 AA holder is temporary, and the Sharks don't have any headroom. The Sharks throttle back the last 1/4 turn of the pot running on the AAs.

    wow, thats a very beautiful flashlight !

    waiting for some beamshots and compares

    i think this light will get very hot under fully brightness - 25V*0,930mA=23,25 * 3 = 69,75 Watts

    my BigMag³ runs at near conditions: 3,7 volt@ 20Amperes = 74 Watts. After 5-10 Minutes @ 100% it will be very hot and you have to dim the light.

    Thanks guys.

    This one is really pushing all aspects of the mod. The cells, the Sharks, the fit, and heatsinking. Using just the (3) Ostars and not the Crees is a bit more rational. Ostars need to have a relatively low Vf of 21V or less when paired with the Cree to stay under the Shark boost ceiling.

    The light does get hot, but I'm waiting for the battery pack to really give it a workout and take beamshots. It draws nearly 80 Watts so it's pretty demanding on the cells.

    Zep,

    The Moby Dick Trinity is state-of-the-art, you are the cutting edge of multiple LED mods! You set the bar very high, you'll have many CPF'rs following your lead. I can't wait to see all of the other competitors!

    Awesome work!

    Zep, what exact model number of Fraen narrow beam reflector did you use for the Ostars?

    And, the light is beautiful, but the pictures of the machine work that was done for the Crees is even more impressive.

    Bob, the reflectors are part #FRC-N1-OE2B-0. Here's the data sheet.

    Benny,

    If you could wire the pack that way and use Emoli cells, that would be possible.

    My power supply is limited to 5 amps, so I couldn't test the draw at the lower voltages, but at 15.5 V it was drawing exactly 5 A. That figures to over 7 amps @ the 10.8 V of the 18 AA holder.

    Hooking the light up to my PS and playing around with different Vin values and the pot turned to lo, I found 2 LED strings would start glowing at around 14 V, and the third around 16 V.

    So a 4s pack at 14.8 V would be ideal, as long as it could supply the current. It would dim to near zero, and make life easier on the Sharks.

    Interestingly the two Ostars that lit first would initially light 5 dies, then a bit more juice would light the last. Of each string the Ostar would light before the Cree.

    Could this be the most state of the art/bad ass flashlight ever constructed? Holy crap man, excellent work! I could only imagine how awesome it must be to have something like this in your collection.

    I need beamshots! How about comparing it to something well known like a M6, Mag85, or ROP High.

    Thanks guys for the very kind words.

    Adirondackdestroyer, I found the light does reach full brightness on the 18 AA when fully charged, so I'll be taking beamshots as soon as the weather clears.

    It would indeed be nice to have this in my collection, and I am growing quite fond of it. But unfortunately for me I must return it to the rightful owner, Griff, who provided the fine host. I'll keep it just long enough to verify the operation and fit with LuxLuthor's pack and complete the beamshots. I will build another for myself, but don't have a host quite as pretty.

    I had to dismantle Griff's HID Ellie to build Trinity, so I certainly hope he doesn't regret it.

    Absolutely stunning! Ingenuity at its best. Can't wait for the beamshots! I do believe this light should make a personal appearance at PF10 though. We could compare it to all kinds of lights!

    Roughly how much does one of these cost to put together?

    adirondackdestroyer, good question.

    The difficulty is assessing the cost is the host. I'm guessing this particular host was well over $500, before any extension tube accessory or 18 AA holder.

    Parts cost for the actual mod, including the pretty exotic low volume CNC milling of the 9 oz. heatsink approaches that figure as well, not including my build time of 8 - 10 hrs.

    Then the proper cell solution, which isn't the 18 AA I'm temporarily running it on. LuxLuthor will work his magic (thanks LL), and 12 Emolis with some expert pack wiring won't come cheap either, but worth every penny.

    So add all that up and you're well into 4 digit territory. Prohibitive? Yes. Worth it? That is all up to the beholder, in this case Griff. I certainly hope he thinks so, and after he receives his light back I hope he will post impressions, good or bad.

    I will build a few more with hosts I have or am having made, probably some with just tri-Ostars as well. They likely won't be as fancy as this one, but also should be more reasonable. But regardless of the particular host, cell solution, and bin of LED, they will all probably be close to 4 digits.
