    Faint New Raw K2 & NS K2

    Raw with K2 UXOL Bin.
    1 Hour + Run time on New (Not so low) setting 45-50 Lumen's.
    High Burst Mode 25 Min's Run time @ 70 Lumen's.
    Same epic Low 10 Hours (8-10 Lumen's) with Regular CR2 3 Volt.

    The new (Not so low) setting is 300 Ma which is very efficient & produces allot of light & not much heat for 1 hour + from the Protected PRCR2 350 Mah Battery.
    You still have the options of full power high (Recommended for burst mode 1-2Mins only)
    And epic Low for huge a 10 hours from 1 Regular CR2 3 volt.
    All these options & more than ample light in a Thumb Size package.

    I only have 9 of the K2 LEDs ATM if Popular I will try to get more??
    The above new Low setting is also available for the Raw & Raw Ns Lux 3 watt TYOK's.

    Cost is £35 www.Lummi.co.uk
    Extra for Nano charger & 2 Stage etc.
    If ordering online please follow up with a email stating K2, 1Hour Low.

    Below photo shows the Raw K2, You can tell the K2 LED by the hexagon Reflector inside the K2 package.

    Nice!

    So this thing has 3 settings and works the same as the others twist more to get brighter, right?

    Thanks

    Very tempting...

    Are these lumen values the actual lumens out the front?

    Also, does it now have 3 light levels (epic low - not so low - burst) or is the "epic low" setting replaced with the "not so low" if you choose that option?

    So what does the "25" mean? Is it 25 minutes on burst or 1-2 minutes?



    Ok, I get it. 1 - 2 minutes on high is the max recommended at one time, for a total burn time of ~25 minutes.

    cheers

    Yes & No with the 3 settings. There are 2 settings High Burst & (Not so Low) Low
    The 3rd Setting (Epic Low) is with a standard 3 volt CR2.

    Lumen's figures quoted are estimated values out the front.

    My Raw collection wouldn't be complete without the Aluminium Raw anyway, and now I'm getting one with a K2!

    Cool news. So this is the same brightness as a T bin 3watt? Are you still doing the U bin 3 watts for an extra £6?

    Regulated? What does that mean?
    Oh I see the dictionary says: Regulated means longer length & more complicated electronics to potentially go wrong!!!

    No just Joking, Regulation is not something I have wanted to build into the Raw Series, Its always been about smallest, simple, bright, quality, practical for Reasonable cost.

    On this 300 Ma setting (Resistor Regulated) & the Li-ions, the Brightness level stays pretty constant between 10 Mins - 50 Mins, Of course there is a fall but the Li-ions do hold there charge well.

    Jiffy: I'll be back in a Jiffy

    I'm Back! Err I would say the K2 U bin is the same a brightness as a 3 watt U bin. Colour tint & Reflectors all play a big part in how bright these appear. The K2 with a Mcr 18mm produces a larger spot going towards more flood than a 3 watt T bin Original height slug with original focal point Reflector, which would give a tight bright spot in comparison. There are many variables out of my hands..
    Yes I still have UXOJ & UWOJ's that we can offer for £6 Extra.
    That's why this K2 offer is a good deal!!!!!!

    All this 'original height', 'original focal point' has got me confused.
    Are you saying that the K2 is more flood than spot?
    Can you compare it to an NS with the cut-down reflectors?
    The original NS were pretty floody but the cut-down reflectors tightened up the spot nicely.
    Is the K2 even more floody than the first NSes?
    I sure hope not.

    I have Just spent most of the Morning assembling some of these
    I will be dispatching orders today.
    I have removed the nano charger from the Raw K2 kit as there is extra work involved in modifiying some components. Price is the same but with out charger.
    Orders already received are unaffected.

    The K2 LED is growing on me, Physically it is a more robust device & the Totally Transparent silicon like dome seems more forgiving than the Lux 3 Acrylic dome.
    The colour Tint from these UXOL is pleasant, the U flux is very bright @ 900 Ma.
    Certainly as bright as any other U bin I have seen before.
    These L Vf are still pulling 900 Ma from the PRCR2, so do not be put of by the L @ the end of UXOL.
    Another bonus ought to be that we are not pushing the K2 to its Limits in the Raw. Infact the K2 is pushing the Battery & the Physical size of the Raw. Hence the Recommendation of high as Burst mode 1-2 mins only.
    The New Not so Low setting means needing the High mode allot less.
    I have made alterations to the heat sink spacer & the Reflectors to produce a nice tight beam with no doughnut beyond 10 Cm.

    Sound good, I can't wait

    Mine won't be shipped until mid august because Rob is currently out of blue tritium vials. I guess this will be a late birthday present from myself then

    So Rob - I'm wondering if this answers the inevitable question: how about the K2 on the Ns?

    If the K2 "pushes" the Raw and CR2 then I suppose it totally shoves the Ns and the 14250 out the door?

    Thanks Rob, I got my Raw K2 this morning.

    My previous experience with Luxeons is limited to a 1w Nuwaii(?) and a 3w Petzl headtorch so I don't have much to compare it with. To my eyes, the beam is superb. As Rob said, there's no doughnut until you put it right up against something. I can't see any blue/green/etc tint in the light either.

    The standard low setting is very useful so I'm glad I went for that. It gets hot really quickly on high so Rob's 1-2 min advice is right.

    The threads are loosening up the more I use it which is good because it was really stiff at first. It's still quite difficult to put it on high.

    All in all, I'm dead chuffed with it. I'm sure it's going to be very useful. This Raw is not going to lead a sheltered life! That's partly why I didn't specify a tritium on mine. Maybe I'll post some pics in a few months of the ugliest Raw around!

    Would be advisable to have a tritium vial(s) if I'm to just carry it in my jacket or jean pocket with nothing else (no keys or change)? I would like to carry my Raw without worrying of anything breaking.

    Unlike the JETBeams, the tritium vials from ORB are nicely recessed.
    They're also so slim that the chances of something making direct contact with only the vial is pretty slim.
    If the whole body of the light was damaged or crushed then the vial would of course break but remember that the amount of tritium contained in these things is completely harmless anyway.

    Thumbs up Re: New Raw K2

    exciting news about a great light!

    I wonder if this could be the best/brightest Raw so far?
    if not which U bin 3 watt would be better?

    WOW! that RED RAW ROCKS!
    I'll rephrase my question:
    Is the new Raw K2 the most powerful white LED so far? or is the U bin Lux 3 a better move?

    Nice to see your Red Raw Solarflare

    The K2 White can be pushed to 1500 mah according to lumileds Specs. There are other white LEDs made up of more than one Chip/Die that are more powerful.
    To my knowledge the K2 could be described as the most powerful single chip/die white LED availble today???
    The K2's I have are UXOL's I.e U bins.

    Just one question ...

    Why is the highest mode (ie. burst) only recommended for 1-2 mins if these
    new K2 luxeons are supposed to withstand much higher currents and junction temperatures than before?
    Change is inevitable, except from a vending machine

    Good Question easilyled, Basically the manufacture covering his backside. The more Torches we sell out side CPF the more education is needed for these still very Niche LED Torches.
    On a more common sense note, I have just Held a K2 NS on Full High for the 20Mins life of the battery. Bare hands and all!!
    My definition of warm may be somebody Else's Bloody hot. Yes it was warm but not Hot I even passed it over to my 4 year old daughter. I warned her it may feel hot & not to drop it. She clasped it tight & said its not hot dad. She then passed it to my wife who dropped it immediately!!!
    If your not aware small High power LED torches run Warm then it may come as a surprise. If you are fully aware & understand Power LED torches have to Run Warm On high settings then you have a dual purpose Light.

    Your quite right with the higher junction temperature permitted on the K2 (150 Deg C) There ought to be less strain on the life of the LED.
