Convoy NEW 6V 8A Driver in M21B XHP70.3 HI
M21B XHP70.3 HI 6500K 6V 5A Driver
Sofirn SC33 XHP70.3 HI 5000K
Acebeam P17 XHP70.3 HI 6500K
I have a spare XHP70.3 HI 4000K R70 that I want to put into a new host. This driver might pair better with a bigger host like the M21C and it will also throw a lot further in a larger reflector. Nice comparison video and good to know that 8A and 5A is not that much different in terms of visual output.
Hello sir. I think this driver would be great with a bigger host. Thanks for watching and your support sir 😊. Please subscribe 🙏.
Good video always top notch.
You know, I was looking at some resources on the Cree website, not the datasheet, the application notes, and Cree actually lists an overdrive current for portable lighting applications for most of their emitters, except the 70.3.
Example, the xhp50.3 they list an overdrive current of 5A at 6V, normally they say 6v3A right. But they give it an overdrive spec. Cree gives all the xhp emitters an overdrive current, but the 70.3 does not have one. The reason they give is because, according to Cree, the xhp70.3 maxes out at 7.25A. That wasn't true for the 70.2, you could take that to like 20A and lumens would keep going up, but I havent seen a test of anybody taking the 70.3hi to the point of failure yet and I wonder if they're telling the truth and it really does max out below 8A, and convoys driver is pushing it too hard. Or maybe it's just a liability and cree is pretending like that's the case. Not sure but I'm curious.
Wish the m21a would fit this driver because it's a great host. Oh well. Lil heat doesn't bother me. Gonna go make an m21b with this driver and a 70.3 right now. Went with a 5700K 90CRI. See how that goes. Again, good job

wow, thx for review. i think i will build using s21b case with 6v8a driver. best edc for self defence 😂.
Hello sir. Wow. That would be really hot sir. Hahaha. Thanks for watching and your support sir 😊. Please subscribe 🙏.
What emitter?
Some people over at reddit were reporting burned spots in 1 of the 4 dies of their XPH70.3. Having 8Amp as an option is welcome but it sounds like a lot.
Someone was saying he was gonna use it for XHP50.3 instead.
Thanks for the comparison. Good job.
Hello sir. I am afraid of burning my led as well sir but no burning at all. C8.2 might be a better host for this driver. Thanks for watching and your support sir 😊🙏.
Naw that was the xhp50.3 hi
I use the 5a driver for 50.3 hi and no issues yet, 8a driver for 70.3 HI. Good reflow job and thermal paste makes a big difference.
@@ttonAb2 I use thermal paste sir. It helps a lot. Thanks for watching and your support sir. Please subscribe 😊🙏.
@@jsplasha Thanks for clearing that up. I found that reddit thread by Tim. Cheers!
Tui yêu những cây đèn đó của bạn,chúng quá tuyệt vời👍💯👍
Thanks for watching and your support sir 😊🙏.
6v 8A is very bright 👍👍
Agree sir. I think it will be brighter with 6500k led. Thanks for watching and your support sir 😊🙏.
good vid
Thanks for watching and your support sir 😊🙏.
Can you please tell what's the difference between r70 and r90? Ali express just got these back in. And I'd really like to know. Thank you. I've been watching your videos for a while now. We all appreciate everything you do!!
Hello sir. R70 is not a high cri led. It's more powerful than r90 led. But r90 led has more cri which can give better colour rendering than R70 led. Thanks for watching and your support sir 😊. Please subscribe 🙏.
Very good comparison. Thank you for sharing, my friend. I would like to buy Convoy M21B, but can I use Wurkkos 21700 battery inside it, without any issues?
Hello sir. I also use wurkkos battery with my m21b sir. No problems. Thanks for watching and your support sir 😊🙏.
@@weerapatkiatdumrong Thank you very much again, my friend.
Hi, i think you should to compare M21B's different drivers with the same LED's to better see the brightness difference. The 5000k version has lower current than 6500k. And maybe your upgraded M21B has LED with higher cri (even less lumens yet)..My M21B 6V 5A driver has battery drain 8.6A in highest mode for XHP70.3 6500K (5000K version has drain 7.8A only..). 6V*5A=30W it is around 2/3 of 45W LEDs max power only. I have upgraded it with new 6V 8A driver, tested, it has now higher brightness, it seems more than 1/3 increasing. The LED XHP70.3 R70 6500K should have now theoretically around 5200lm, coz i measured Uled 6,5V by led current 7,3A, battery drain increased to 14,8A. Yes, the host has lower brightness than LED's 5000lm due to the reflector, but i do not have equipment to test it. Despite this, the brightness is on LED's max and amazing now, for such small flashlight, almost no competition on market for this price. But yes, it is heating enough by max 5th level, and stepping down faster, but it will stay after few minutes on increased brightness value as well. The 4th level has increased from previous 2,5A battery drain to 4A now, i estimate around 1500lm, and that is avesome as well. 4th level has now comparable brightness like "1800lm" flashlights by turbo (with battery drain also around 4A), but M21B's 4th level brightness will stay much longer time..
Btw, your channel is super, good job.
Hello sir. Wowwwww. Thank you very much for sharing this useful information sir. I like it very much. Thanks for watching and your support sir 😊. Please subscribe 🙏.
@@weerapatkiatdumrong dear sir, you are very welcome. I am always impatiently awaiting and watching each your new video. Good luck.
Did you ever sort out your issue with the 17mm 8a buck driver, I now have two in m21b with adapters and they have identical throw to my two others with the 22mm 8a buck driver.
Hello sir. Not yet sir. Maybe because I don't use it often and I don't use long turbo sir. But in Thai flashlight community, one member reported that his driver is broken already due to long turbo. Thanks for watching and your support sir 😊. Please subscribe 🙏.
What's wrong with the 17mm 8A buck?
Excellent review! Thank you! The Acebeam P17 is a nice flashlight.
A question, does the Acebeam P17step down quicker than the standard M21B with the 5A driver in turbo?
According to 1lumen.com, P17 turbo lasts about 1 min 15 secs and then about 15 seconds later it steps down to about 1000lm. I think M21b 5a can last longer on turbo. It's not as bright as P17 so not heat that much and this can make it last longer in highest mode. Thanks for watching and your support sir 😊🙏.
@@weerapatkiatdumrong
Thank you for replying!
And thanks again for the great reviews!
I compared the 5a and 8a drivers in two L21B hosts and the more focused hotspot seemed to make a more noticeable difference to me in person. Do you have any videos with the 50.3 HI using the 6v 5a drivers? I can’t seem to find anyone doing this even though the 50.3 should be fine for more than 5a. I’m going to try it when I get my order of 50.3 HI, I ordered some 6500k R70.
Hello sir. No sir. I haven't tried or seen anyone using 5a driver with xhp50.3 hi. But I think it's possible to hold that current. I have tried xhp50.3 hi with 4a driver. It's bright and fine. Thanks for watching and your support sir 😊. Please subscribe 🙏.
@@weerapatkiatdumrong I received my order of xhp50.3 hi (6500k r70) and I tried them with the 5a driver but I didn’t think they were bright enough so I actually tried one with the 6v 8a driver lol. It is brighter but I don’t know how long the emitter will last being driven this hard. I have it in an m21b and compared it to my m21b with the sft70 both using the 6v 8a drivers and I think the sft70 is still a bit brighter and definitely has more range (candela). I feel like the 50.3 hi is better for multi emitter flashlights but in single emitter flashlights I don’t really like it that much. Also the 50.3 hi 6500k is cooler white than the sft70 6500k.
@@lumntoob999 Great to hear your experiment sir. Thanks for watching and your support sir 😊🙏.
@@weerapatkiatdumrong I thought you might find it interesting, I’ll comment here again if that light has any issues.
Amigo fiquei curioso será possível o lede SBT90.2 com sua capacidade máxima de iluminação no convoy M21B?
Yes sir. But that needs really a good modification. Convoy Facebook page posted long ago that somebody uses sbt.90.2 in S16! I really want to see the beamshots of that flashlight. Watch this sir. Thanks for watching and your support. Please subscribe 😊🙏.

hi very nice videos hi war you buy the leds and the driver???
Hello sir. I bought it from Shopee Thailand. You can buy it from AliExpress sir. Convoy Flashlight Shop is there. Thanks for watching and your support sir. Please subscribe 😊🙏.
ok thx man @@weerapatkiatdumrong
how about switch, can endure 16A, because using 8a 6v driver? thx
Hello sir. It's still fine. No problems sir. Thanks for watching and your support sir 😊. Please subscribe 🙏.
What do you prefer? sc33 or m21b 5a? Im trying to decide what to buy
Hello sir. It's hard to answer. I like them both. Sc33 has good ui and it's very bright. Its ui is better than m21b but m21b has spare parts. M21b is not IPX8 . So you have to decide whether which one suits your need and usage. I have a lot of m21b because I like its appearance and I can change led and driver. It is immoral. Thanks for watching and your support sir 😊. Please subscribe 🙏.
Thanks. How long does m21b with 8a driver last on turbo vs sc33?
well .... +18 watts in such a small case is not a good idea. I think this driver is for large flashlights. But yes, it’s very bright, 45 watts all the same, it was still worth taking current measurements at all brightness levels
Hello sir. I should install it in c8.2 sir but I insufficient resources. Put this driver in m21b is the easiest for me because I still have one with the old driver for comparison. With a bigger host and 6500k led, I think it would be more powerful sir. I set mine to mode11. Highest is very hot but it controls the heat well. Med is fine. Very bright and just warm. Thanks for watching and your support sir 😊🙏.
@@weerapatkiatdumrong❤
hi this driver fit on sofrin on sc33???
Hello sir. I think no sir. It's not easy to put this driver in Sofirn light because it was designed differently sir. Thanks for watching and your support. Please subscribe 😊🙏.
thx very help full great videos
can you put the link pls......very nice job
How about acebeam e75 4500 lumen?
Hello sir. I am sorry. I don't have it sir. Thanks for watching and your support sir. Please subscribe 😊🙏.
XHP70.3 HI 5000K in M21B with high CRI?
Not a high cri version sir. If it's a high cri, it won't be as bright as my 6500k 5a version sir. Thanks for watching and your support sir 😊🙏.
Acebeam wins, 2nd position M21b 5amp
Hello sir. I think if my 6v 8a is with 6500k led, it will be brighter than the one with 6v 5a led. Putting this new driver in c8.2 would be better. Thanks for watching and your support sir 😊🙏.
@weerapatkiatdumrong the 5000k is clearly brighter than 6500k with 5a driver. These flashlights are incredible. I'm glad I didn't go with the sc33. I just wish I could customize flashlights like you. I know 8m vs 5a driver will get got quicker. But does it drain battery quicker too?
@@sethmichael8188 I think it consumes more power as well sir. Thanks for watching and your support sir 😊🙏.
