I've just received a new ThruNite TN30 and have observed the following: When running on Turbo with UltraFire 2500 mAh 18650 cells (yes, the cheap ones), the light flickers incessantly.
I've been advised that this is most likely the result of the cheap cells not being able to keep up with the current demands of such a high output light, which seems reasonable to me.
I've ordered some quality EagleTac 3100 mAh 18650 cells to verify, but won't have them for a couple days (and I know not to try CR123As as the light is only rated for 13V).
So the question is, has anyone else encountered this flickering when running a TN30 on turbo, with UltraFire cells?
I also have a NiteCore TM11, and am aware of the flickering problems that some people had with theirs, but mine always ran/runs fine on the cheap cells. Were the cells used perhaps a contributor to some of the early TM11 flickering issues?
FYI – I also have the TN31, and it runs perfectly fine on Turbo with the cheap cells (less than half the total output, so lower current draw).
Thanks in advance, and best regards,
John C.
