OK, good, that sounds like normal operation for a NANJG driver. Whew. I thought for a minute Convoy were silently changing drivers.
The NANJG style of mode switching is not as good as the short off cycle method, but I have gotten used to it.
Great review! i was looking for something small for my dad, must be very compact like this!
I guess this is the best pick for the money?
How many ANSI lumens would this be ? 500? at least a guess? 
C8 vs M2 vs M2? which one offer most output? thanks.
Thanks to your excellent review I decided to buy the C8 convoy, and I’m very happy with it.
Great quality plus the price is great.
Recently bought an ultrafire C8 T6 with Smooth Reflector for a change and comparison.
C8 throws better than the M2. Both should be about the same brightness in lumens. M2 has a smaller head
My measurements are not calibrated, so I have no idea of ANSI output. I think it is somewhere close to what I measured though and posted in the review.
Glad you like the light, Perikov. As this was your first post, Welcome to BLF!
Thanks!
I have long reading the forum and learning!
greetings to all
How does the Convoy C8 compare to the XinTD v4? Is it less bright? And is the battery life the same?
I believe there are members that have both lights. I do not fit that category so I cannot compare. My guess is the XinTD V4 will be brighter mostly due to the XM-L2 emitter it uses.
The V3 might be comparable in output to the Convoy.
I only have a xinTD v3 (no convoy)… but from what I have read I think they are pretty comparable in brightness. The xinTD should have a bit more throw because it has a slightly deeper (smooth) reflector.
How many minutes would the ultrafire 18650 battery deliver on the highest mode?
That is going to depend on the actual capacity of the battery. Usually the marked capacity will be inflated on xxxxFire branded lights.
I have a 3000mAh ultrafire. Would that translate to about an hour on high?
I’d guess that the light would remain in high mode for about an hour, but the actual output will begin to drop after 15-20 minutes. As the battery voltage drops, so does current. This will extend runtime, but not at full output.
The light begins to drop out around 3.7-3.8V, meaning as long as the battery remains at or above that value there will be full output. Under that, it will be less than full output.
Also, because the output decreases gradually you may not notice until it gets down to about half output or less.
Those TF are crap, sorry man.
Agent80,
I have 1 or 2 of those ultrafire batteries that are ok, quality seems to vary. I have not tested these batteries in my c8, but I would guess about an hour, if its a fairly decent battery. I recently tested a panasonic unprotected 2900mah, and got about 1hr 20 min. Nice thing is the light starts blinking when voltage gets low, I think battery was at 3.2 volt,IIRC.
I bought a “Raptor” battery from the local( South Africa) Chinese shops,( Latest cheap Chinese offering?) which says 3800mah, weighs 31 g, whereas a decent battery weighs in around 45g, and it lasted 20 mins in the c8.
So battery quality will make a huge difference…
Hmm any discount on the XinTD C8 V4? its 30$ not exactly cheap…
trust me, the xinTD is worth it. if you have more expensive lights you will appreciate the quality of it for the price.
All what i care is decent build quality and solid output. Is the XinTD 12$ better then Convoy M1 which is already great? if it is, i might take it into consideration.
The Convoy is just over $15 with BLF code. The XinTD is about $14 more. I do not have the XinTD, so I cannot compare, just find it difficult to believe that the XinTD could be $14 better than the Convoy.
Thanks, i tought the same.
BTW what do you mean by 15$ never saw price like that for the M1 2.8A U2.
