Thread: NEW WORLD ORDER 4 THROW - V54 World that is HaHa*

    I wonder if you're getting differing lux bins on that tape reel of Osram LEDs, leading to different lumen outputs per LED.

    We won't know until I try in similar lights but yeah I'll ask my supplier
    People loves throw because the grass is greener on the other side...Flood lights cant reach the other side ;-)

    It's something the suppliers can't control I don't think cause Osram doens't bin their leds.

    This was brought up here before and on BLF. It[bin variation] certainly seems like a possibility.

    How can the U21vn have 465Kcd and the D1Svn have ONLY 270Kcd when the size of the head/reflector is not much different???

    MAD777 brought up reflectors designed for specific LED'S. That may be true but I do not think it could be so significant in this case.

    I asked V54 and he was not sure as to what the reason is.

    The Reflector of the U21 is a whole 9mm wider, that's a rather large difference. Now, if the Black Flat in the D1svn were to output the same 800 lumens as the U21vn, the throw would certainly start catching up, maybe to around 350k-380k cd or so, but that 9mm difference probably pushes the U21vn to the 460k cd mark.

    Right, I noticed that the head of the U21 was 9mm or 1/3" wider. [59mm for U21 and 50mm for D1S]

    I guess that translates to the reflector also.

    I wonder what the difference in depth is? I have the U21vn XPL version so I can look at it more closely.D1Svn arrives tomorrow.

    Just my guess,,I still do not think a 1/3" difference in reflector size would make a 200Kcd difference. The depth/type of the reflector and other variables that I do not know about must play a part.The output may also play a part.But then I think of some lights that throw 500Kcd and are only 700 lumens compared to ones that are 1800 lumens and throw much less.Lots of variables, some that I do not know or understand!

    The U21vn with Black Flat puts out 800 lumen, the D1svn only 650. That extra 150 lumens will increase throw quite a bit.

    The power difference would increase throw by only 11%, so if the D1Svn had 800lm it's throw would be 1154m.

    Ok that would mean:

    D1Svn = 270Kcd=1039m of throw

    With 800 lumens[11% increase] it would be:

    333Kcd=1154m of throw


    I was told this 3 or 4 years ago. Lumens are NOT the determining factor for LUX/beam distance.

    My TN31mb is 700 lumens and is 470Kcd

    My TN32 was 1700 lumens and 200Kcd.


    Obviously different LEDS,[XPG2/XML2] same reflector and optics HUGE difference in throw w/ the TN32 having 59% more output and 58% LESS CD's!

    My point is under the right circumstances you can get a LOT more LUX with a lot LESS lumens.

    For the 2 lights in question the LED is the same[supposedly].

    My guess is that the optics along w/ possible bin variation are MORE of a factor than 150 More lumens.

    I'm as excited as anyone about the far reaching throw of the U21vn with Osram. But I want to praise the XPL version, too. I haven't used it in awhile, but I took it out on my walk tonight. Definitely one of my most useful lights. Great performance for its size, economical, and what a large hot spot!

    The U21vn XPL is my FAVORITE mid ranged light. I much prefer more lumens and large hot spot.

    The D1Svn will be an exception for me,,,tight beam and low lumens.

    Differing optics is the biggest reason for the performance difference of the U21vn, again 9mm is quite a difference. Bin variation could very well be the factor for the 150 lumen loss, or maybe that Vinh couldn't drive the Black Flat as hard with an unprotected 18650 vs an unprotected 26650 (which I doubt.)

    150 more lumens will result in more throw when the optics and emitters are the same, while a 9mm larger reflector will also result in more throw.

    I agree totally. The U21vn XPL was my first V54 light, and 20 lights later it is still the most useful and impressive out of all of them.

    I honestly think a shaved dome sst40 or hd u21vn should replace the xpl version.
    It would get more lux and lumens I predict.

    I would be all for more lux and lumen, but it would need to have the same wide beam profile of the xpl version.

    I know right. Itís such a great light. I actually emailed vinh this morning if a 70.2 can possibly be put in the u21vn.
    Id be happy with even a 50.2.

    U21vn XHP70.2 is a no go. Just got an email from the man himself.

    I take that back...its coming in about 1 to 2 months. ;-)

    That is just wonderful! 3600 lumens and 135 kcd is my prediction.

    What about the OSLON in this light? Should be able to break 1MCD?
