It is the latest version with integrated shelf. I had to modify the driver hole and the driver to get it in there.
For the driver I filed down the edges right up to the via holes in the ground ring, this allows it to just barely fit where the stock retaining ring sits.
From there I machined out the 17mm driver spot to the same size as the retaining ring threads, leaving just a small 1-2mm shelf for the driver to sit on. Then it just assembles as normal and everything fit perfect.
Convoy could easily modify the driver pocket in production to fit a 20mm driver, very minimal changes. Retaining ring I did not modify at all, so the center opening is already large enough.
The mod could be done with hand tools, or a dremel if you have a steady hand, but I have access to a lathe, so it was much faster and easier using that.
I have a very similar light with the same host (UltraFire C8 on gearbest), and the host is not bad (not as good as a Convoy C8) but for $4, I would say let’s go!
Nah, chances are it’s a POS. Thin-wall tube, LatticeBrite LED, plastic reflector, thin crappy undersized Al pill, probably a generic cheap switch.
I got a bunch of C8 clones to use as hosts… not worth the ag. By the time you get done swapping out the crap, you could just buy a real genuine Convoy host and get quality.
If you’re not gonna overstress them, like pushing 1A-2A or so through UV, deep-red, etc. LEDs, no prob. But if you intend on pushing them harder and cranking out more heat, nope.
Hello, below some pictures of KDlitker C8.2, compared to Convoy C8 clear - I would describe it as C8 XML on steroids - not that much throw, but very wide hotspot.
XHP 35 with single 18650 is not good idea. Boost driver from 3,6V to 12V is expensive, low efficient, bulky, low runtime etc.
That is why at the moment best achievement with good battery is around 1600 - 1400 lumens and that for short period of time.
This KDLITKER C8.2 Cree XHP50.2 White 6000 – 3000K depending on LED, 2600 Lumens
sounds very interesting.
Any info about step down timer in high (2600 lumens) mode?
Thanks for the sharing Jensen. Well for me it’s too much hassle to do all these as I don’t have the necessary tools, skill and also being lazy. I would just modify one of my cheap existing hosts which has 20mm driver opening, or just off to buy the KD C8.2 lol.
Confirmed - I tried up to 5 minutes, when body got really hot at high mode. No step down observed. I like this type of hotspots - not that far reaching, but really illuminating wide at ~ 100 m. You can’t use the light for extended time at high though - it really gets hot fast. Head gets warm 2minutes, hot, but touchable 3 min, body hot @ 4 min., then 5 you can't hold it - this is 25 degrees Celsius in a room. Besides that, the quality of the host is OK, matte black and smooth, glass and reflector are very smooth, I could’t see AR coating. Overall happy with the light, cannot supply data for currents or lumens.
Hi, I have the following question: I have 2 convoy c8 clear new version with xpl-hi u63a, one mine and one that gives a friend, measure torch with luxometer at 6.5 meters with batteries panasonic ncr-b 3400 mah and stock produces 60000cd, Is a reasonable value? Next, the mine was modified with BLF controller A6, by pass cables springs 22 awg and with battery sanyo ga, produces 81000 cd, is also a reasonable value? Last modified my friend’s flashlight, stacking 4 amc 7135 in source controller of 8 amc, produces in the tail 4.15 amps (logical) and 76500 cd, what is the limitation the type of led? Or flashlight being rendered low? Sorry for the long, greetings !!
