I got Yezl Z1 yesterday and here are some notices:
It has very thin - and much less - threads and body is different - worse - than Brinyte PD08 (which looks the same). But it is crazy bright and fits a pocket so as long as its threads are ok and nothing breaks, I very much like this light.
I registered and cost delivery is 5$ air mail,
35$ is big.)))
Dx UltraFire P10 18$, + KD xm-l 9$, + KD AMC7135 Circuit Board 5$
ONLY 32$ + FREE R5 AND DRIVER LEFT,
OR change Dx UltraFire P10 ON Dx TrustFire TR-801 13$
ONLY 27$ +free Q5 and Driver.
I've got one, and it is a very nice light. Review here. Heat is going to be a very big issue in an stainless steel body. Keep the current down - I suspect an XP-G R5 with the stock driver would be better.
Wow that’s weird Mine has the longer threads like the bryinte on the right … It is 6 full turns before it drops off the threads … The head side does look a little bit shorter threads and went 5 turns before it fell off the threads . Wonder if your tube is just flipped around?? …I do like my bezel ground down smooth it looks and feels much better …My biggest complaint with this light (xp-g version )Is the body,specificly the center tube The flat spots on the body makes it slicker for no reason ,just so they have a place to advertise .What I want is just all knurling . This is the same reason I’m afraid to buy the D-11 Nitecore …Silly flatspots
No, it isn’t flipped, it is a different body. Even the lanyard holes are ultra thin on Yezl. I suspect different batches or even built by different factories with the “same”(!) specs…
I received my AW 2900mAh protected li-ion and 1600mAh IMR cells yesterday. With a full charge, the protected li-ion puts out the rated 2.5A but the IMR does a full 3.5A on high. I noticed that there is almost no difference in brightness from 2.5 to 3.5 amps. After doing some reading of Crees product sheets, I see that the XM-L is rated at a maximum current of 3A. It doesn't say what happens when you go beyond that.
One thing I did notice, the head of the light would get absurdly hot in seconds but with the protected cell at the right current, it was a bearable amount of heat.
Am I turning my light into a heater with the IMR cell with no increase in light output?
