Thread: The DEFT EDC is out!

  1. #1

    Default The DEFT EDC is out!

    Just got the email notification! 40k cp, 5.3 in. long, and powered by an 18650! Seems pretty exciting, can't wait to see the reviews. It's priced at $199, and I'm tempted to pull the trigger, but don't feel like I have enough info on it yet. They've set up a shop at the omg lumens site.

    That looks very very cool. I once joked with saabluster about using an overdriven XP-C, and he dismissed it out of hand!

    Could not resist, and ordered one looks like a fun little light

    Ordered one. Was hoping he would make a light like this.

    The pics from the omg website doesnt look like the original deft, the thrower. The beam looks defused. Wating for some beam shots to click the checkout button.

    Yes those beam shots are zoomed in from 522 and 735 feet away. I have never taken beam shots before but will try when mine arrives.

    You crack me up. I was delaying posting any information on the light here to give all on the email notification list a chance to purchase first. It's all good though.

    Well I would have dismissed it out of hand sometime back for two reasons. The XP-C in the old DEFT platform creates a beam that is in my opinion too small. With a smaller lens the beam gets larger and thus becomes acceptable. I refuse to make a light that is in my opinion unusable just to reach a higher lux number. The whole package must work. It is all part of my philosophy of "right sizing" the components.

    Second the XP-C was only recently available in the Q4 bin. All the XP-Cs I had tested prior to this could not be driven hard enough to outdo a high binned XR-E. That has now changed. These little XP-C Q4s are incredible.

    Lux is 40 cp as mentioned on my site or 40,000 lux @1 meter. It has 230-240 emitter lumens although that is a far less useful spec for this type of light. For a dedicated throw light the lux number is the one the matters most.

    Many have asked for some more beamshots and other info. I will get that up as soon as possible. Also just to avoid the apparent confusion the DEFT-edc is, like the old light, based on a host which has significant work done to it to make it a premium light. The host is the Skyray. We then gut it and use our own components. It is no longer a drop-in type light as that is far from optimal for heatsinking especially when pushing the limits. And you all know I push the limits. That is why the LED is mounted to a solid copper pill cut on our CNC machine.

    When choosing the material to use I didn't pick just any copper. I chose the highest conductivity copper I could find(99.99% pure OFHC). It is more expensive but has far better conductivity than the vast majority of copper out there and is almost as good as pure silver. I also made sure to buy annealed copper as even the hardness of the metal can affect the conductivity.

    The outer body rings that come on the Skyray are junk and they therefore get junked. We make our own high quality rings in a metallic finish that compliments the light beautifully. I've yet to be able to get pictures that really show how nice they look on the light.

    We put quite a bit of effort on deburring the threads and proper oiling so the threads are silky smooth. Conductive grease is also added in some key spots to assure reliable operation and a low resistance circuit. To aid this as well a silver coated beryllium copper spring is used on the positive battery connection.

    Anyway hopefully it is clear there is a bunch of work that goes into these lights. I will start my own thread soon and have some more info that people have been wanting. -Michael

    It's a Seraph body, yes. I wonder if the P60-dropin standard is preserved or whether the internals are permanently installed.

    The XP-C is an interesting choice. I had an SOSFLARE light that I got from Newegg a few months ago that used an XP-C behind an adjustable-focus TIR optic, and while I ultimately decided I didn't like it very much, the emitter could put a (dim) spot on a tree much further away than any of my other lights could touch.

    No the P60 setup is not used. That setup is junk in my opinion. That is if one is trying for high output-which I am. As mentioned in my post above the LED is soldered to solid copper. This in turn is mounted in the body using an interference fit so the heat has a highly effective thermal path to the outside.

    It's not so good for heat conductivity, but it's great for flexibility. Of course, I don't think anybody would buy a special DEFT model just so they could swap the light engine for something more pedestrian, so the loss of flexibility doesn't matter in this case.

    Perhaps it's a bad question to ask, but how much is the XP-C emitter overdriven in this setup? As I recall, their OEM specs (admittedly designed for inferior heatsinking) don't allow for much wattage.

    The LED is run at 1.4A which is quite beyond the max spec. Trying to squeeze every last drop out of this LED. Of course max spec is set not only for less than stellar heatsinking but for lower bin parts and on top of all that to be able to last 10s of thousands of hours. The combination of extremely good heatsinking, high bin parts, and lack of a need for tens of thousands of hours in use allows me to push it far beyond spec.

    In my tests the LED will hold steady at 1.6A with good heatsinking so I decided to back off that a bit for reliability's sake. Pushing the LED this hard and keeping the P60 format is a recipe for a dead LED in short order. You can also see why I went "overboard" on the thermal path front. P60 has a place in the market just not in my lights.

    Awesome.....Awesome.......Awesome.

    I been wondering when these would come out.

    In the beamshoots in your website the Aspheric beam doesnt show CREE Wires???? My Aspheric XR-E R2 show that square with lines, but does XP-C Aspheric not show those????

    Thanks,

    Just for curiosity, how big is the XP-C die? Just wondering about A/mm^2 vs A/mm^2 for comparing to other emitters. Either way, running at 300% recommended max current is quite a stout overdrive.

    Are you referring to the current spreaders or the bond wires? You can see the current spreaders on a white wall but not in normal use. The bond wires do not show however. It also does not have the artifacts that the XR-E had(rings).

    The XP-C die is .68mm x .68mm. That makes it about half the surface area of the XR-E depending on the chip used. It should be noted that the actual die is rated at 1A max so 1.4A is not that far off from that.

    Are you using the XP-C or the XP-E? The XP-E can take 1.4 Amps with
    your method of heat sinking, but the last time I checked the XP-C was only
    rated at 500 mA and could be safely driven to 750 mA.

    I know not what course others may take; but as for me, give me a PEAK flashlight, or give me the dark.

    Oh yes. Knowing what you do to poor, innocent little LEDs that never hurt nobody, the need for a good thermal path is a given. Mostly I'm surprised you're able to run so much power through a small-die emitter without overwhelming the one part of the thermal path you can't control -- the N-P junction inside the emitter die itself.

    He's using the XP-C, because it has an even smaller die than the XP-E.

    I'd be curious to know if the OSRAM Golden Dragon has a similar die size to the XP-C. It looks like it might actually be smaller, to my eyes.
