Because i can`t post my question in the review section, i do it here.
I know that the h50 can be used with 14500 lion, but i couldn`t find runtime graphs for all the modes.

Have somebody a link to them, or doesn`t they exist?

greetings from germany.

Cheers,:thumbsup:

PS. Why am I bumping this? dunno...I just happened to be looking for this info at the minute


However quoted from the same thread

Preliminary Conclusions:
  • A very unique and versatile little light - a true flood lamp.
  • Initial impression is that it is very well made.
  • Excellent circuit design that accepts a wide range of batteries, and has very good pre-set output levels and runtime efficiency on standard batteries.
  • Lacks true low modes on 14500 – and Hi mode is dangerously bright on my sample. However, the light shows an unusual low power “moon mode” feature, even on protected 14500.

just trying to answer the thread title.

I know that there isn't a low mode on the H50, I use the H50 + 14500 on my belt every night.

This is the only graph I know in existance, while it does not include all modes of operation, it does give the op some sort of reference when estimating runtimes.:huh:

The lack of a low mode with 14500s in the h50 was reported to be changed in the newer production models.
I couldnt find any runtime graphs either.

yes, the H60, which is driven , by design, a 18650 li-ion...with a UI way more complicated than that which intrigues me to buy one:shrug:

i did not thought of the h60. There where reports, that the first batch of h50s had the issue of nt offering a low mode with 14500.
The second and following batches of h50s do support a low mode with 14500s though.
Reports said, that the second batch h50s would run at slightly lower output rates on 14500s than on alkalines but with the same modes avaible.

I was in know way bashing the answer you gave, i was just a little worried by "and Hi mode is dangerously bright on my sample"....so i justed wanted the OP to know.

But if you use it with a 14500 daily, i feel comforted that it would be fine.

No worries :grin2:
Given the specifications of the Q5 I think the LED can pull it off with no ill effects, but since the overhead voltage of the regulator is unknown I personally will not explicitly recommend this sort of driving method to anyone. It will get hot though, but I've never ran it to the temperature of my old EDC: Surefire L4. Sometimes I wonder how surefire manages to pull off with the KL4 getting this hot and not melt solderjoints:eek:

Not daily no, but its a pretty good area light to stroll in the parking lot at night trying to find your car...as its always been for me on campus, especially after a hardcore exam:ohgeez:
