BYB Super Bright CREE T6 LED Adjustable Flashlight

It’s my privilege to report on many different flashlights – most of them being more high-end lights with a price tag of $50, $100 or more. Here I’m happy to report on a light, or to state it correctly, a light package that you can still purchase for only $16.99 at Amazon!

Included in the package:

-The light.   A nice, hefty aluminum handheld light with a CREE XM-L T6 emitter;




























-An Ultrafire 26650 6800mAh rechargeable cell;
-A charger for the battery;

-A sleeve to allow use of an 18650 cell
-A carrier that will allow the use of 3 AAA batteries
The light is unremarkable in operation. Uses the familiar forward “clicky” style switch with activation of high, medium, low, strobe and SOS. You can move through the modes by activating the light then lightly pressing the button. Or you can click the light on and off repeatedly to move through the modes. There is no mode memory.

An equivalent battery alone could cost $12-20. While the charger is definitely an inexpensive one, having it included is a nice bonus. And being able to operate the light off 3 common AAA batteries in a pinch is also nice.

What I enjoy about the light is the focusing head, allowing for the beam to be shaped anywhere from a pure flood to a pinpoint aspheric spot. You can literally see the etching of the LED chip when set for pure spot.




Definitely a package worth looking into, especially for the bargain price!

Love firearms and flashlights – and they go well together. I’ve been admiring and writing about quality flashlights for about 9 years…built my own integrating sphere….done a few mods. Proof positive that a 59 year old can still love toys!


  • Ricky Kittle

    Link to buy?

  • thedonn007

    What is the battery life with the different batteries? Also, what is the lumen output?

  • Paul White

    might put four of these in my emergency kit (one for each of us). Pricier flashlights can be nice but I’m not dropping 250-500 bucks on flashlights for the family.

    • greek preparedness

      But for a light more cash you get an Ultrafire C8 flashlight that it is way better than this thing.

  • Mystick

    These have been available through FastTech for years.

  • The days of buying $150+ streamlights has been over for me. I’ve been buying these cheaper LED lights for the last few years and I don’t get worked up when one breaks or it goes missing. I always a few of them around.

  • Michael R. Zupcak

    I just bought a Fenix PD-35 TAC that uses the same LED but I paid $80! At least I had Home Depot store credit to use. The Fenix is small, though. Way smaller than it looked in pictures and way smaller than a Mini Maglite. I still don’t have batteries, though, so I haven’t tested it yet.

  • Scott Tuttle

    there’s plenty of cheap chinese flashlights with XMLs in them. The trick is the quality control varies wildly so prepare for unexpected duds. the same goes for lifespan: switches and drivers go out randomly.

  • nova3930

    Ultrafire has several nice little budget flashlights available on Amazon. They’ve got a 300 lumen mini model with a Cree for $5 that I bought a half dozen. I put one on the lathe, one of the mill and one on every work bench. They’re harbor freight cheap and actually put out useable amount of light…

  • Steve

    Seeing the shape of the LED when you focus the lens into ‘spot’ is a sign of piss-poor optical design. Coast makes a smaller focusing light called the HX5 that runs about $24 on Amazon and accepts a rechargeable AA battery – this is my personal EDC light. Doesn’t include the same goodies (charger/Lithium battery) as this one, but you get what you pay for, I suppose.

    I’ve had a few of these cheap fist-sized lights in the past and I just find them much less useful then a well-designed AA or AAA (or even 2xCR123) sized handheld.

  • t_reese

    All the different lighting modes is nothing more than ‘tacticool’ BS. A light needs to simply turn on and turn off!

    • iksnilol

      Not really. Too bright light blinds you at short ranges (when you’re for instance searching for your keys) while a too weak light can’t light up at distance (for instance when spotting coyotes or something).

      Strobe, at least SOS, is nice to have for emergency signalling.

      • t_reese

        Like I said, turn on and turn off!

        • iksnilol

          Okay, I turned off my light. I can’t see anything now, how does that help me?

          I turn it on, it is too bright. Again, useless.

          Being able to change the light output on the go is useful.

          • Cymond

            Also, the low modes help extend the battery life when you don’t need a bazillion lumens.

      • Swarf

        Strobe and SOS should always be a seperate switch. They are 98.99% useless modes to click through in your way to useable light output. Faux tactical BS.

        The switch could be shaped like a small penis.

    • RICH

      Quite evident ythat you have never been in need of a light in a tactical situation ! Check out a different page… yard lights, maybe !

      • t_reese

        You missed that one by a mile Rich, I’m retired Military with combat experience and also former Sheriff’s deputy. I’ve seen and been in more than my share of tactical situations.

        • RICH

          A narrow focused beam as well as a flood beam are both desirable attributes in a light other than just an ‘on & off’ switch. I have used several makes and types of lights throughout my career from spots to penlights. A light that offers more than one operating mode has always been beneficial. IMHO !

        • RICH

          Granted, the strobe & s.o.s. are pretty much useless…….

  • Fruitbat44

    LED technology has come along in leaps-and-bounds. Which is why you can get the performance from a cheap flashlight which would have been . . . well, I can remember when the must-have-tacti-cool torch was the Maglight. -sigh-

    • greek preparedness

      From my perspective, i have stopped servicing such lights. The cost of replacing the circuit board is more than half the flashlight’s value.
      BTW, that battery is of low quality. And makes some big claims. Current QUALITY 26650 do not go further than 5200mAh.

      • Fruitbat44

        Hmm . . . like a lot of modern technology, and I’m not saying it’s necessarily a bad thing, it is easier to replace than repair / maintain.

  • Sgt. Stedenko

    Plastic lens. Nope.
    Non protected cell. Nope.
    Poor English grammar in the product description. Nope.

    I’ll stick with my FourSevens MMX360 which I paid $60 for on Black Friday and enjoy that 10 year warranty and the fact that I can talk to the owner in Atlanta if I have a problem.

    Not sure whether this is a turd sandwich or giant douche, but I’m not willing to waste $17 plus shipping to find out that some no name Chinese company without a mention of warranty has used off-spec LED binnings while throwing around terms like “military grade aluminum” when they couldn’t tell you what that meant if you could get a hold of this fabulous company.

    Too bad the author doesn’t understand the value of American made and owned.

    • He understands but we cover the expensive and the budget lights and all those in between. We want readers to have a choice.

      • Fruitbat44

        Good policy.

    • iksnilol


      20 vs 60 usd. If they both do the same I find this to be a hard choice.

    • Dan M

      I do understand and always prefer American made and owned. And by the way, FourSevens lights (of which I own 6) are manufactured in China. When I write up a Surefire or Streamlight that is manufactured in the US, the comments are “I can buy a Chinese made light for ¼ that and it does the same thing.” As Phil points out, if the light is made available we’ll review it so readers have a choice.

      • Swarf

        Home run comment.

      • Cymond

        Yeah, they’re made in China, but with good QC oversight. I love all of my FourSevens lights, even if they do make some odd design choices.

  • Don Ward

    Instead of CREE. They should have named the flashlight the Creed Adjustable Flashlight.

    Can you make me brighter
    To a place with blinding LEDs
    Can you make me brighter
    To a place with golden beams

  • Hellbilly

    Using the 3-AAA set-up will result in parasitic drain of the batteries (the batteries will drain even with the light turned off). If you buy this and plan to leave it in a glove box or other “sparingly used” location, do not use the 3-AAA set-up or you will have a dead flashlight when you need it. I’ve thrown-out all of my cheap 3-AAA lights because of this. At least this one can also use 18650 batteries.

    • Marco Antonio Gonzalez

      That is the normal behavior of everyday NiCd. Get a low discharge one like Panasonic (previously Sanyo Eneloop) and you get a full year storage time

    • iksnilol

      All batteries do that to some extent.

      Always keep the batteries out of stuff that isn’t used often,.

  • greek preparedness

    Guys stay away from the zoom flashlights. I have taken
    measurements of the lumens and throw in both positions. In one sample I

    Lumens – zoom out – zoom in
    High: 620 – 150
    Medium: 380 – 85
    Low: 130 – 30

    That means that 3/4s of the light is lost in the tube when
    the user focuses the flashlight to a sharp beam. This is because the LED is
    very far away from the optic and see a lot of dark tube.

    • Sir TuberKopf

      Lumins are a lousy performance number. It is purely a measure of the brightness measured at the brightest part of the beam. With a reflector and some optics I can make a pin point beam using 2 watts of led light power and it will have more lumin than a 7 watt led light that can turn a room into daylight.

      I was given a dead laptops battery pack that I took the batteries out of. They were 18650 high end lithium batteries. From Amazon I bought a charger and a half dozen assorted flashlights that used that battery and all claimed to be very bright.

      The one that reported the highest number of lumins was the most useless, it projected a beam about two feet across at a hundred yards. It and one other went into the trash, they weren’t worth the postage to return.

      The best was of course the most expensive at around $14. I bought two more of those and was still surprised to find significant differences in light output. These super bright LEDs seem to have significant variation in manufacture.

      I imagine with the very high end and expensive flashlights you are getting higher quality parts through tighter QC and a high scrap rate. LED’s that fail QC probobly end up in those $5 flashlights I had to toss

      • Dan M

        Measuring lumen output may not be perfect, but it is the accepted standard. And when measured with a proper integrating sphere, it is not a pinpoint or spill that is measured. Light is collected and uniformly reflected and scattered around the sphere’s interior so that the output is UNIFORM.

        As for perceiving the brightness, an increase from, say, 400 to 500 lumen will be all but un-noticeable to most. It takes an increase in output of 4 times to perceive double the brightness.
        I agree about the variation in LEDs as it relates to lower priced lights. That’s one of the reasons that some of the better lights cost as much as they do. As for the batteries, agreed.

  • floogy

    Looks like the myriad of cheap zoom lights from eBay or Chinese direct buy site. Not terrible, but durability is often pretty suspect. I have a Nitecore and a couple Convoy lights. Usually the premium paid for Streamlight and Surefire is for durability and real lumen ratings.

  • Dan M

    Folks, I have no “dog in this hunt” and have no need or desire to defend this light, but this is a good light and a great value. I’ve had (literally) hundreds of lights pass through my hands and still have dozens in my possession and have seen the best and the worst. This one isn’t the quality of a Surefire, Malkoff, Streamlight, HDS, etc……even Zebralight.. But it’s pretty darn good. And quite frankly, it looks to be more substantial than the Four Sevens lights that have been mentioned. What do you get from Four Sevens? A much more customer friendly experience and a warranty/company that will stand behind their product. This BYB is a crap shoot – Amazon might stand behind it, though. All that said, for a decent package for bug out bag, truck light, tool box light, etc., this light wouldn’t break the budget and you would be losing much if it did go bad. When I absolutely have to depend on a light – to be absolutely sure that it’ll work – then I’ll carry a Surefire or, better still, an HDS or custom McGizmo.

  • Sir TuberKopf

    I don’t know if any manufacturers are listening, but for a tactical flashlight all I want is “on or off” at full blinding brightness, a zoom is fine. Anything complicated is too distracting and potentially unsafe in my opinion if used in a self defense situation.

    For a tool box flashlight I do like “dim, bright and off”. Some of these lights are so bright as to be unusable for close work, the reflected light is too bright, but if you are under a car engine looking up in daylight it can take a lot of light to backlight dark engine areas.
