Thread: SBT90 G2 LED - The 2020 Thrower LED

    Default Re: SBT90 G2 LED - The 2020 Thrower LED

    Coincidentally, I just received my SLN with P60 SBT90 De-lens drop-in. It arrived a few minutes ago.

    I placed an Acebeam 5100 MaH 21700 battery in it, and turned it on.

    For a small one LED reflector it projects a very intense beam. Vinh rated mine at 3580 lumens.

    I left it at full intensity for a minute, and it became very warm but not hot.

    To me, this LED makes this very impressive flashlight even more impressive, but I wouldn't leave it at 100% for very long. Even at 10% power or so, it is pretty bright.


    OK, I had a few minutes more to play with it, and adjusted it to mode 10-4-2, or Firefly/5%/33%/100% with no mode memory.

    Now it is even more useful as well as impressive. Firefly projects a small very dimly lit circle 10-15 feet away in a relatively bright room. 5% would be perfect for most general flashlight use, and 33% when more light is needed.

    That's awesome, Star! I think the SBT90 and Lilvortex have the highest 'cool factor' in the SLN. What a sexy set up!

    Im on the interest list.
    Hoping my budget is in my favor if and when they are released.
    Will put it up against my GT90 to see who the badass really is.

    I agree, since I now have both versions

    From what I've read, the triple W2.1 P60 drop-in may be the best SLN version "between" the SBT90 and the Lilvortex. I'll only know when I have the triple W2.1.

    Thanks Vinh, I'll get a 40T

    Would a twisty tail cap for an SLN with SBT90 improve the output, too?

    I know it would for an SLN with LilVortex.

    These are gong to be such cool lights!

    Okay, assuming a 40T cell and performance at turn on, I'll go with;

    T27 = 4900L 565Kcd
    T28 = 5000L 685Kcd

    Gotta be in it to win it, pure stab in the dark guesstimate:

    t28= 3900L 650Kcd

    T28vn90 @ 2 seconds 5000L 760Kcd, 1744m
    WOW so much more OTF lumen.....

    At least we know SBT90 G2 clearly blows away XHP35 HI

    T28vn90 performance is incredible! Since both uses the same LED, driver, and battery, what do you think is the cause of the large output difference?

    So interesting! I kind of understand the discrepancy in throw given the T28 has so much more reflector surface area but I wonder what accounts primarily for the lumen differences?

    You'd almost have to swap the LED's from one light to the other before understanding further what contributes to this.

    Thanks for the fun, Vinh!

    I thought the T27vn90 would be a little closer to the T27vn W2.1 with its impressive 575Kcd. I certainly didn't expect the T27vn90 to come in 2nd place to the MT35vn90's 4800 OTF lumens, especially with the DeLens mod.



    ...but they are about the same size head and I guess it just comes down to things like drivers and resistances.

    I would imaging the K65GT handles heat much better than the T28.... if The K65GT were throttled down slightly would it run for a good stretch around 4000L? Two very amazing options. T28 is obviously lighter but IDK that it would be any less cumbersome than the K65GT all said and done......

    It kind of comes down to 4000mah compared to 10,400mah (VTC5) or 14,000mah in the K65GT if you use LG3500's. No matter the cell formula in the K65GT, it will see less voltage sage.

    The shape of the T28 being what it is, I agree that the K65GT wouldn't be anymore cumbersome to belt or pack carry unless weight was critical. Still, I image small hands will like the T28, especially if it's only being used intermittently as a security light to quickly spot things or to used in conjunction with a headlamp.

    For me personally T28 is much easier to handle than K65GTvn. Its a much smaller and lighter light over all with just the head being equal.
    K65GTvn does have the extra punch and more runtime

    I was thinking of you when I mentioned smaller hands. I could have bet money you'd like the T28vn90 for handle size and rear switch... especially after measuring the performance!

    Crazy thing is I would still take the T27vn90. IN person the difference in performance is not that big but the size diff is. I am just really lazy lately. I only take the smaller lights out. haha

    That's great Vinh! It makes me that much more excited for the T27vn90. Lately, it's about the largest head size that I care to take hiking. It usually rides on my hip, or side pouch on my hydration pack, but sometimes inside the pack if it's not night time yet. When it is night time, sometimes I'll just stick it head up in my pack pocket to free up a hand momentarily. Larger heads make all of those things more difficult. I've always liked the size and performance of the T27 but since receiving the K35GTvn, it has replaced the T27. However, putting the SBT90 into the T27 will likely make it my main hiking "spotlight" again, unless I'm doing something that needs the runtime of the K35GTvn. As performance has increased, I've been able to use smaller and smaller lights and still get the same performance that larger lights used to cover. Thank you for creating so many fun SBT90 options!

    Vinh I know you've been super busy but I'm excited to hear your thoughts or measurements on many of your recent SBT90 builds. Favorites, failures, cell compatibility, etc. For example you've built a D3Cvn90 SBT90 5700K DeLens DriverVN4 running on a 16340!! With maximum 16340 discharge currents of 2-3C how does that work with this LED since it can pull more current?

    Also, the
    D1vn90 SBT90 5700K DeLens... This sounds amazing! I would love to hear about these when you have time.

    Maybe just a video briefly talking about the SBT90 builds you were most impressed or surprised by.


    When you have time

    Hey Vinh, is that video Patriot mentioned done yet?? LOL
    Just kidding.
    Be well my friend and take your time putting these lights together. All of us know that our our orders are custom and will come in due time.
    In the delicate work you do, remember that slow is fast (minimizes mistakes). Besides, our anticipation of receiving a new light is half the fun!

    I know that even if someone orders specs, the "before" testing is extra work for you. So many of us appreciate being able to share in this data with you because we enjoy the hobby so much. Thank you for passing it along to us!

    BTW, I think a nearly 5% gain in throw is pretty darn cool, when we're talking about lights of this performance level.

    Any chance you might try it in a Thrunight Catapult V6???
    Add some copper to manage the heat???
    Anyone (looking at you Patriot - have any ideas on rough numbers regarding output and throw?
    I think it would be a MUST HAVE if Vinh could get it to throw over 1000m...thoughts anyone?
