KDLITKER C8.2 Flamethrower!

Hi,

First, let me get this out of the way: this is not going to be one of those excellent, in depth reviews that many of the members here do. I lack the capability to produce such a document. What I want to do is describe a light, and the figures I recorded.

The light is perfect in appearance. The finish is flawless, and the light gives a secure grip. The only threads I observed were on the tailcap. They were smooth, but I lubed them with a spray Teflon lube, anyway. The LED is well centered, in a nice looking reflector. No dirt, dust, or fingerprints on anything. What common features the light lacks are a low moonlight mode, and there is no USB recharging. I don't know that this last should be expected at this price point. I think KD is trying to supply a quality product at the lowest price possible. I'm glad they did/

Now, to the performance. I picked up this light at my mail drop last evening, and I immediately pulled the 18650 from my usual carry light, and I tried it out. There was too much light pollution there, so I got a better idea scanning the fields later for deer, or whatever. Yes, its bright, no surprise there. The lowest mode has enough light to avoid stepping in used dog food. The next mode up is enough for walking alongside a dog. The third mode is ideal for scanning the entire area where you are, and the fourth (top) mode is OMG. The beam profile is a bit different than what I am used to. I would describe it as "floody". The hotspot in a C8 reflector is not well-defined, not as much as it is in a Mag reflector. I like a defined hotspot. I generally do not illuminate a dog with the hotspot. I use the spill, to avoid blinding them. But if I use the second mode, it all works out well enough.

I measured the Amps at the tailcap, and was surprised at the result. So I charged two Pana 18650s, let them rest for 8 hours, and re-did the tests. My batteries, rested, showed 4.16 Volts. The low mode was 0.015A, the second was 0.374A, the third was 1.411A, and the fourth was 6.26A! Note that these levels do not correspond to the advertised levels. I much prefer the levels as they are, and not just because of the 6A+ turbo mode. I'm really happy with the lower modes. I don't need the turbo, but i'll take it. 3.0A would have been fine with me. It does get warm at this highest mode, and it eats batteries for lunch. My useage of this last mode was in 10-15 second bursts, just to scan a field. If the driver has a thermal stepdown, I did not use it for a long enough period to bump into it. For my normal use, it's a moot point.

Bottom line, for a hair less than $30, I like this light, and I'm going to buy another.

Cool, it seems like a good all-around bright light. About the current you measured, the driver spec is 3A to the LED, but it is a 6V LED and the driver is a boost driver. So it must draw more than 3A from the single cell in order to get the power.

It's a nice light. It isn't as bright as my one (so far, I'm such a lazy slug) remaining 50.2 Mag. A lot easier to carry, of course. I thought the current would be more than 3.0A at the tailcap, but double that seems high. Maybe my batteries can sustain a little higher current than the tested KD cell.

Over the years, I have developed a beam profile fetish. I like HI emitters in P60s, for more hotspot. I generally don't care for them so much in a C8, too narrow. But I'm wondering if a dedomed first gen 50 might be fun in the C8 reflector. I'd be worried that it too would be too narrow, and I would have built another shelf queen. The size of the die might make it inherently floodier, maybe. I would need a 17mm driver, though.

It makes sense that it takes roughly double the current when you remember that power is conserved. The voltage of that LED is twice that of a traditional 3V LED so it takes twice the power to send 3A through it.

A dedomed XHP50 die is about 1.5x that of an XPL HI, and so the beam would be about that much larger as well. You could use two aspire 18350 cells and a FET driver. That would be a bright little light. But if you are all about the beam profile you might not like the resulting donut hole.

Lexel,

Being as it's a C8, I assume it's solid. There are pictures on KD's site.

Any beamshots would be nice. I have been looking at the light for quite sometime but lack of reviews put me off. Which driver does it use?

Haha i still have those MCEs on my Triple Maglite. Thinking of swaping it with XHP70.

Driver is a 20mm H1-A. I like the driver personally, I built my own C8.2 out of a Convoy host which I machined to accept the 20mm driver. A bit over 6A from the cell is about right for 3A to the emitter (it’s closer to 2.8A stock). Mine is modded for around 3.5A to the emitter.

If you wanted to swap a de-domed XHP50 you wouldn’t need a new driver, just a simple emitter swap.

rizky_p,

I can't do pics, so no beamshots. I can tell you, though, it's not a thrower in a C8, and even in a Mag it's not tight.

Btw, 50.2d are easy in a Mag. DD, 2 26650s, it's all good. I'm going to do a 70.2, but that will be a 4D with a 12V emitter.

Thanks for the review Ollie. Do you perceive any PWM pattern in all the modes?

Jensen567,

I took the chicken way put for now, I ordered another light. Apparently the pill is different.
Sometime soon I would guess we will see dropins when the demand for complete lights tapers
off.

bibihang,

So far no joy. Sometimes I can see PWM by shining the light at a fan. It was not noticeable.
It is supposed to rain, and I can see it with the raindrops, but the weather is not cooperating.

Try the shower. Wink

Looking for:

5” parabolic reflector (for recoil light)

rizky_p,

Yeah, this weekend should be a flashlight-building marathon. That's a bit misleading, because I've already done most of the "building", so much of it is soldering 2 wires, and it's done. I should get to it.

bwl123,

It's really bright! It's full power, so pointing it at any reflective surface is nauseating.

Jerommel,

The shower test was not as definitive as I had hoped for. This may be because the water is exiting under pressure,with greater velocity, rather than just falling. However, testing it against another C8, that does show PWM, the observed results were very similar, so I'd have to say that this light has it, too.

And now a confession: I LIKE PWM! Being out in the rain is like having jewels rain down on me. To put this in perspective, this is obviously coming from someone who doesn't have enough sense to come in out of the rain. My dogs are out in it, then I'm out in it.

Thanks you Ollie. Even though the H1-A does seems to have PWM, it’s not like we have any other 20mm boost driver choice at the moment so gotta live with it anyway. Sad

Hi Ollie: So does the light actually put out 3800 Lumens or even near that? A quantitative comparison to similarly advertised flashlight would be great maybe a ceiling bounce for a relative brightness comparison? but Haikelite SC02 with coupon is tempting probably also close in performance.

Ha Ha Ha, thank you for the wonderful review and I’ll keep your confession a secret ha ha ha,
I’ve been trying to buy one of these C8’s and some drivers for must have been a couple hours now and really wondering if I just blowing some money on a joke of a light and then I think KD’s site crashed or went haywire for some reason but I’m very glad now,
I came here and saw your review and I got all my questions answered from your review about this light and a really good laugh to boot.

rizky_p,

They advertise 2600 lumens. As someone else mentioned, it’s maybe more like 1800. When I retired, I left my cheapy light meter for my coworker to use, so I’m just guessing. As I read it, the sc02 is a different beam profile; very floody. A 50.2 is not a thrower, but it does have some reach. If you put it in a Mag, the bigger reflector adds some distance. One other thing, the sc02 is a 26650 light. The way the C8.2 sucks the life out of an 18650, the 26650 makes some sense. This is a personal preference, nothing more, but when I’m out with the dogs, it seems that I usually have an 18650 light on me. I have several 26650 lights, but I see them as car lights. The extended run time could be a benefit. What I like about the 50.2 is not so much the hotspot, though I do like it, but also that the spill is bright enough to be useful. Contrast that with the Manker U21. It has a “Wow!” hotspot, but the spill is dim. I’m contempating putting a 35 HD in there. Ollie

Still no beamshot pictures? Most people don't like flashlight with PWM.

Without any beamshots there's no proof on your claims.

Sorry but what??
Putting 2k lumen on a surface nearby and looking right at is exactly that.

And this emitter and driver combination is well tested and known by now.

T18,

This may sound excessive, but if I could keep only one C8, this would be the one. I'm fickle. When I got my first XP-L HI I was in love! Much like the Manker U21, it was great for scanning the fields at night. But for both of them, the dim spill eventually put them on the shelf, for general use. I think the narrow beam of the HIs is a good match for the P60 reflector, but other than that . . . I would like to see a 50.2 in maybe a 3" reflector, but I wouldn't carry such a thing very much. My beloved Mags are a bit much, too. The smooth bodies do slip into a back pocket, and of course there is always the very useful Niteze swivel holster. For general use, an 18650 C8 does it, and this C8.2 is the brightest I know of. The modes suit me. Apparently I am not real sensitive to PWM, so that is not an issue.

And while I'm on my soapbox . . . It doesn't have USB charging. Oh, boo hoo! I majorly don't care. When I find my lights getting dim, I pop in a charged battery(s). I'm back in business, right now. I don't have to put my light out of commission waiting for the batttery to charge. No additional hole to the inside of the light, for water to enter. I appreciate lights like the U21, which comes with a charger. Pair of batteries, good to go. I must have a dozen chargers, and who knows how many batteries in various sizes, so USB cable charging is very much a non-starter with me. I don't want to pay for an onboard charger that I won't use.

USB charging is one of those "hot, gotta have" features right now. When the cable gets flakey, and you discover that the light has not recharged, it will make you cranky. Meanwhile, a good charger and a power source (I have converters in both my vehicles) and a spare battery will mean you have light, whenever you need it.
