Although not mention in the description, there is almost certainly a step-down timer from Turbo mode to High when using a 14500 battery. For comparison, following are the parameters for the original Lumintop Tool AA:
Battery
Lumens/Runtime in
Low
Medium
High
14500
8/ 28+30
95/ 4+00
550/ 0+45
Alkaline
7/ 36+25
25/ 11+00
110/ 1+45
Ni-MH
7/ 30+30
25/ 11+40
120/ 2+55
The orignal Lumintop AA Tool has no mode memory, and no Turbo or Strobe modes
No mode memory
Always starts in Low
No noticeable PWM
Some owners report that the SF14 goes spastic when NI-MH batteries are used. See this thread for more info. I haven't seen this problem and I have been running an Eneloop in my SF14 for weeks. Sofirn reports, however, that the anomaly is fixed in SF14 V2.
Only had two SF14’s one of them did have a fit on NiMh. low and med would work fine but it would have a flashlight seizure as soon as it was put on high mode. Figured it was just mine. Didn’t know it happened to others. The other one worked fine though. Gave the fit thrower away and sold the other one.
Might grab another one though. Thanks a bunch ActiveAl
I am happy to own a SF14 because it performs well using a 14500 - with a nice mode spread, and impressive High mode output. It also has a decent tint with no noticeable PWM. I really have no need to run a Ni-MH in my SF14. There are other AA/14500 flashlight in my collection that are better suited to use with Ni-MH batteries anyway such as the UltraTac A1 and the Jaxman E3 (currently en route).
Oh I agree. I love my little A1 with a NiMh. Besides the Zebralight, it’s one of my favorite AA’s to carry around. Don’t have the Jaxman, I will take a look at it though.
I just saw a flashlight and its price less than 1 dollar! Amazon.com.
How it possible to make a flashlight in this $0.61 price?
I had added a few flashlights in the black Friday which was under $10 bucks Black Friday Flashlight Deals 2023 [Plus Cyber Monday] but never has seen this price flashlight
A red flag for me is that the seller is probably lying about the lumen output of this flashlight. According to Cree, the max lumen output of the XPE famliy is 307 lumens. If you check the XPE-R3 datasheet you will note that the max luminous flux given for this LED is no more that about about 120 lumens. Based on this misrepresentation, the product is probably crap.
