    Are Nitefighter and/or GearBest dead?

    I love my BT40S light. I ordered it on the GearBest group buy over the summer and have used it a few times this fall. It's fantastic. Good battery, good beam, good brightness, and good mounts...for $39.

    I like it enough that I want another (or a BT21) but it seems that either the Nitefighter or Gearbest connection has been broken. Discontinued product? Shady distributor? Company closing?

    Is there a reliable source for Nitefighters now?

    There are other sources. Kaidomain and Dealsmachine to name a few. "Availability"? and "reliability"? are the golden questions. If I were going to buy another Nitefighter lamp it would be from anyone but Gearbest...unless they were the only ones who had the product and I had no choice.

    Thanks.

    Any non-Nitefighter options that may have a more reliable source? Can't beat the price/lumens of a Nitefighter at ~$40.

    Where did you hear that Gearbest wasn't carrying them anymore? BT21 still appears to be for sale there.

    Kevin, check out Amazon (us) for the "Revtronic" BT40S:

    http://www.amazon.com/gp/aw/d/B00R1J...XgL&ref=plSrch

    Tigris already posted that Nitefighter had to change their name due to Streamlight having a fit. So Revtronic = Nitefighter.

    I can't find it right now. It doesn't appear to be in the big BT40S review thread, so it must be tucked away in another thread. Perhaps tigris99 will chime in.

    Guys this has nothing to do with any company going under or anything else. Its a simple trademark conflict with Streamlight for the nitefighter name being used on amazon. So for what nitefighter sells on AMAZON ONLY is rebranded. It still nitefighter, just to avoid any further trademark conflicts.

    I have a BT21 on the way from Gearbest. It was backordered for whatever reason but that happens to stores all the time so I didn't think it was anything to be worried about.

    They keep on telling me I can delete my own order, and there is a trash-can icon, but I can't find it.

    Also they deleted my ticket-request to delete everything from my previous order except for the battery, even though I placed a new order with more things. It seems clear they plan to run the clock out so they can mark it shipped so that they can say they can't make the change and I will end up with a double shipment.

    I tried to live chat during their business hours many times, and it keeps on saying "
    Our agents are too busy to sever you now."

    Too much stress to deal with them. I can't see ordering again. AliExpress is so easy. I placed an order for $13 impact shorts last night with free shipping by ePacket, and it is already marked shipped.

    Ahhh, nice... fast shipping. http://amzn.to/1NlgeZR

    My neighbor bought the "revtronic" light and it seems really nice, didn't know about the name change, no idea about battery life tho....

    They also list the BT21 and claim they ship it within 24 hours.

    gearbest shows they have 30 BT21's, I ordered last week and it shows in transit already. they had 85 at the time I placed order.
    I've been inside too long.

    I would question if they really have them in stock if they take a week to ship them. I think when they get an order, they order them from the maker, and when they come in, they reship them.

    BTW, I see a BT21 listing on eBay that claims 1800 ANSI FL1 lumens. I was under the impression that they could not make 1800 ANSI lumens. If it is not 1800 lumens, they are really asking for someone to file a defect claim, and then the seller has to pay two-way shipping even if the return policy says buyer pays return shipping. Most likely they will settle for a partial refund. The solution is for them to not inflate the lumen value.

    Although that is only a solution for honest people, as eBay buyers make false-defect claims to get partial refunds or to return things without paying for shipping.

    Do you mean they can't make the ANSI FL1 claim? Or that the light can't actually be 1800 lumens?

    According to this old test (testing includes mounted on Aluminum vs. so many other testing done on copper only) an XM-L2 @ 2.8A puts out just under 1,000 lumens, so double that for the BT21 (which is driven at 2.8A per emitter at least with fresh battery pack). Keep in mind that test is without considering losses (in BT21's case for optics). If we assume it's 980 lumens @ 2.8A, then subtract 20% for losses (conservative), that's 784 per emitter, 1568 lumens total. Claiming 1,800 lumens is probably a bit high. 1800 lumens is possible if the optics really only cause 8% loss OR if they are using higher binned emitters than included in that test.

    I am fine with the concept of estimating ANSI lumens in good faith based on the current, bin-lookup, and then removing 15%.

    I was unaware of anyone thinking the BT-21 was an 1800 lumen light.

    If it is a 1600 lumen light, that is awesome, and it makes me wonder why I got any ~1200 lumen Yindings at all. Why not only get BT21s for bar and helmet and change the optics to 10 degree for helmet use? Optics are only 80 cents a set. Is there anything better about the Yinding besides you can currently buy it without a battery kit?

    In any case, looks like I am covered because GearBest won't edit my order down even though I requested it multiple times, so I will end up with three BT21s and two Yindings. Then I will sell the extra.

    The Yinding is easier to mod to XP-L's and/or add a remote switch for helmet use and is smaller / lighter. Depends on user's intentions.

    That 2.8A per LED is based on battery pack draw and I am not sure of the actual current through the LEDs. In reality comparing otherwise identical lights, you'd be very hard pressed to see any difference between 1600 and 1800 lumens. It generally takes 4x the lumens to double the brightness seen by the naked eye.

    What benefit occurs when you modify to XPL? I looked it up and they seem to be about the same lumens per watt.

    Looks like the Yinding is 59 grams the the BT21 is 65.

    I meant XP-L HI emitters. They increase throw substantially. Pictures are worth a thousand words: see this link. Hopefully you can view the mouseovers correctly.

    The mouse-over where one shot looks like it is through a blue filter and monochrome, and the other is full color, is a stunning example of why chasing the highest lumens at the expense of light quality doesn't make sense.

    Also it is pretty neat how the natural LED shows vegetation that is not visible with the cool LED.


    You made some good arguments for the BT21 here:

    "It's pretty much better than the Yinding all around. Better build quality, more mass for heat management, "off" out of the mode cycle, and a bit more output current"'

    Seems like the Yinding does not have a usable daylight strobe mode and I don't think I would use a continuous light in the day.

    Not having off in the cycle is a huge plus for the BT21.

    I assume you're talking about a different set of mouseovers and not the Yinding mod (since neither Yinding pic shows Cool White tint). Note that some of my earlier photos were screwed up by using a wrong white balance setting making the light tints look bluish when in reality they were crisp pure cool white (i.e. the GearBest Triple XM-L2 light is a good example and perhaps the one you're referencing).

    Yep, hence our push for people to move to using neutral white tints, though I'm of the minority preferring a 5B1 tint which is on the warm end of neutral white.

    Not having off in the cycle is a huge plus. Why do I want my light to go off when riding and about to go down-hill so I want to change from medium to turbo mode? Long-press should always be off. Strobe should always be hidden.
    I agree. Exactly why I purchased the BT21 for helmet duty. It was just that the Yinding was easier to mod to try XP-L HI's.

    The Yinding does have a slow strobe accessed by a long press. I actually like the slower strobe better than a seizure inducing fast strobe.

    I found a video of the BT21 strobe and it didn't look like my ideal for daylight riding strobe.

    How much, if any, current does the BT21 draw when off? I notice that the power light is off when the light is off. That is good. Can you practically leave it plugged in when not in use?

    What about the Yinding?

    Not sure what thread but I just answered that question lol. All these lights have a power drain when off. Not many that use external battery that dont have a small draw. Never a good idea to leave a battery pack plugged into any light as it will eventually drain.

    No more DHL for me. These companies have seem to found a way to have DHL take longer and cost less than normal DHL. Some kind of special extra-low grade service.

    I am on my second package that looks about three weeks from Germany. ePacket from China is twice as fast.

    How many hours to drain the battery about 10%? A day?

    To further than line of thinking, why do I leave the battery in my Fenix P32 flashlight when it is not in use if one cannot keep power hooked up to an LED driver?

    The PD32 uses a normal clicky switch, not a momentary switch so that is safe to leave batteries in because the switch completely cuts off the battery from the driver. All momentary switch lights draw some current, some much more than others. Bike lights are so simple to disconnect the battery that you should just do it regardless of how much drain there is.

    EDIT - I can't find any measurements I took on current draw while "off".

    Considering my BT21 (with Glowworm spot optics) has out-powered my Gloworm X2V3.1 (1546 measured MTBR lumens) by 5-10% in all my lux tests (bounce/center-beam) I see no reason why with just the optic change it wouldn't make more than 1600 lumens. Stock frosted optics are very inefficient but I still estimate the BT21 @ 1450ish lumens totally stock. BT21 bar and helmet is one of my favorite setups.

    Little problem is that MS and SS connectors can wear out a lot faster than any other components of a lighting system. In my past decade of night riding experience, I've lost battery packs, lamps and chargers due to this weakness. So now I resist the temptation to disconnect the cables when the battery doesn't need to be topped off and I anticipate riding the same bike again within the next few days. Yeah the cells might discharge a little, but not enough to reduce run time too significantly within that short frame. This holds true even with my lamps with control buttons that stay illuminated when the unit is off, and of course with Nitefighters it is even less of a worry. Over time, batteries are gonna drain by themselves anyway. I'd much rather preserve the connectors, because they're such a headache once they've gotten fiddly.

    My three cents.

    Seems the two fine pins within the female end disintegrate, while the tip of the male just wears down further and further. Will rummage through my collection in the storage room, see if I can find any units left that I haven't already chucked and try to take pictures.

    Already having problems with some relatively new chargers not making acceptable connections — they'll light up green when plugged into either the mains or a battery but I'll have to rotate the jacks over and over before the indicator led will turn red and start charging. Will often go back to green way before charge is complete. Happened with two new MS chargers and a couple crappy chinese ones, as well as my four year old MS charger and MJ-816 (one that came with cylindrical battery case from Geoman). Bought new MS extension cables to cut and solder into the light head and battery pack when I get the chance, not gonna attempt resuscitating any of the bad chargers (still have five working units left.)

    Hmm, I've seen described problem in cheap MS clone after connecting to 5.5/2.5 battery. But it's quite simple to fix - just insert a thin awl (or small flat screwdriver) between each pin and the edge of its slot opposite to the hole...

    I don't think it's so much about trademarks because the Streamlight product ( cheap torches ) is called "Nightfighter" while the Chinese lamp is "Nitefighter"...a different spelling. Still, this is close enough to screw with search engines that are geared for steering different spellings automatically. Since Streamlight was first to market their product on Amazon, allowing two products to be sold with similar spellings would have not been fair to Streamlight...at least that's my take on it. You can still find the Nitefighter on Amazon by searching "BT40S", etc. Only difference is you won't find the word "Nitefighter" as the manufacturer on Amazon.

    It depends on your preference for beam pattern and throw for a bar light. Bt21 will have more throw, bt40 has a more even flood

    And don't forget about the difference between the interfaces. BT40S has up/down controler so you don't have to cycle through all the modes. I find the large button easier to operate than the single small controler on any other lamp, especially when wearing gloves, though that has not been everyone's experience. And of course the BT40S lacks a strobe mode, in case that is important to you.
