It is widely available in many variants from many sellers. It uses an 18650 lithium ion battery, and sports a Cree XPL HI emitter.
The big problem is that the stock firmware on the Convoy has this stupid "blink on low" so called "feature" that indicates something about when it is ready to be configured. This didn't seem bad at first, but becomes more and more annoying over time. I have really grown to hate it in the worst way. That aside, the Convoy is a really great light. I need to figure out how to flash the Biscotti firmware into all of my lights.
Some people are all about maximum brightness, and for those misled souls the BLF may be the best light. The BLF has a FET to deliver maximum current for the brightest modes, along with a current regulator to allow PWM for a moonlight mode. This is a clever combination, but since I could care less about a super bright mode, it does nothing for me. The bright modes on the Convoy are more than bright enough for me.
XPL HI V2-1A 6500-7000K XPL HI U6-3A 5000-5200K XPL HI U6-4C 4200-4500K XPL HI U3-7A 3000-3300KInterestingly, you can also choose how many 7135 power drivers the flashlight comes equipped with. I am more interested in long life at sensible brightness settings than the absolute highest brightness, so I ordered my lights with 3 drivers.
7135*3 output current 1050mA 7135*4 output current 1400mA 7135*6 output current 2100mA 7135*8 output current 2800mA
I was charmed by the illuminated button. The listing says 7135x8 and I selected the U6-3A color bin. This has the Cree XPL HI emitter. With eight 7135 this can put out 2800mA, so it ought to be bright. They offer 4 color bins, as follows:
V2-1A 1000LM 6500-7000K White Light U6-3A 940LM 5000-5200K Sun Light U6-4C 940LM 4300-4500K Neutral White Light U4-7A 840LM 3000-3200K Deep Yellow LightI ordered the 3A and really want Neutral White. I was nervous about this, but now that I have the flashlight in hand, it is perfect and exactly what I was hoping for.
Switching between mode groups is simple, but not obvious if you have never done it before. Select the lowest brightness and wait about 5 seconds, the flashlight will blink briefly. At this point, hold the button down half way for a few seconds (the light will be out while you are holding the button down) and you are done. Actually it seems to work to simply turn the light out shortly after the afore mentioned blink. Beware though if you do this in routine use as it will switch modes. This has already bitten me.
This is a very nice light, the only possible misgiving would be the lack of a moonlight mode. In general, I very much perfer the Biscotti firmware, and it will be a good day when convoy starts shipping this as the default.
The full brightness is very bright, very possibly more than I will need except on rare occasions. A clip is supplied, which I will almost certainly never use. Thankfully it is not on the light, so I don't have to scratch the light up removing it. An overly complex, but very nice lanyard is supplied. Since I don't trust the clips, I will probably use my own lanyard made from mini-paracord.
I paid $18.36 each for these. They have the Cree XM-L2 emitter, which is virtually indistinguishable from the supposed snazzier new XPL HI. I ordered mine with the T6-3B tint (5000K) and eight of the 7135 regulators. Each gives 350 mA, so 8 of them gives 2.8 Amps of current at full brightness. In retrospect this is silly and the minimum of 3 regulators would be just fine, but no harm done.
I switch it immediately into the second group (without flashing modes that I hate). This gives me 5, 40, and 100 percent current. This means I get no moonlight mode. I will have to figure out how to flash the Biscotti firmware to get that. Also the low mode is 5 percent of 2800 mA, or 140 mA, which is plenty bright enough for my uses, and definitely not a moonlight mode. The high mode at 2800 really serves no useful purpose -- especially with the wide beam of the orangle peel reflector. It might make some sense with a more focused beam for certain uses (like shining down deep mine shafts).
The Convoy has springs at both ends of the battery chamber, so it will definitely accept flat top cells. It does have a strobe mode, but the Biscotti firmware only offers it in certain "mode groups", and group 2, which I like the looks of, omits it. And if you buy the light with Biscotti firmware, there would indeed seem to be an excellent moonlight mode.
The Biscotti firmware has one "mode group" that offers 0.1, 1.0, 10.0, 35, and 100 percent -- presumably of the max current, which in my case is 1050 mA. I find I use my BLF-A6 in a 50 lumen mode (134 mA), so my bet is that the 10 percent selection will be exactly what I want most of the time. The Moonlight mode on the BLF-A6 draws 3.4 mA, so the "0.1" mode on the Convoy should draw 1.0 mA -- which should definitely be a moonlight mode.
