    New Zebralight H31

    I think that on the H31 the modes are .5lm and 5lm so it should be even more visible. All I can say is that on my SC50w there is a big difference between .6lm and 4.4lm modes. Have you tried setting the Novatac closer to .5lm (.47lm?) to directly compare the lights?

    4Sevens Maelstrom G5 *SHIPPING VERSION* Review (XP-G R5) - RUNTIMES, BEAMSHOTS +

    Re: There is no spoon, but there is a tree. Yeah, it seems a bit too much. Especially since regular Quarks don't have such a great efficacy in the moon mode. The question is how accurate is the specification that we know. Many manufacturers in the lower modes seem to provide "not less than"...

    4Sevens Maelstrom G5 *SHIPPING VERSION* Review (XP-G R5) - RUNTIMES, BEAMSHOTS +

    Re: There is no spoon, but there is a tree. Probably simply because one uses PWM and the other CC.

    New Zebralight H31

    It seems that ZL specifications for moon mode are not really precise. I read about the new H501 and your H31. On the other hand, I have an SC50w and the moon mode in it, specified at similar level - 0.6lm, is really low. If my eyes are not dark-adapted, I can look directly at the LED without...

    KD all-in-one charger

    Yeah, it would be too high also for my liking (at least it is still not dangerous). It's just a $5 item from DX so we cannot even be sure that the one you bought has the same design as the ones I have. The protection shouldn't have any effect here so it seems you were unlucky. My two chargers...

    First and last li-ion light

    I don't know how the Nano charger works but I haven't seen any mention in that thread of it charging past 4.20V. All that is said is that it trickle charges. It may be obvious but trickle charging doesn't mean that the voltage will rise. A Li-Ion cell voltage will naturally drop down when...

    First and last li-ion light

    The charger was tested in mdocod's charger roundup thread. As expected, it does not use the CC/CV algorithm, it is painfully slow, it overcharges the cells and doesn't terminate the charging at all (it trickle charges). It is yet another charger that sacrifices the cells life and user's safety...

    First and last li-ion light

    I's sorry for the off topic post but I'm afraid I am not confusing anything. When with a surprising frequency the recommendations are given to the products offered by one particular vendor, it starts to be a vendor advertising for me. When Carrot writes "I buy my AW cells from 4sevens.com" what...

    First and last li-ion light

    In theory a LiCoO2 cell can leak but as many people in this thread pointed out it seems to be really unusual and unheard off. I'd also guess that what you are seeing is something originating from the light, not the battery. BTW, Carrot, how on earth is your "excellent charger available at...

    The Real Reason for Throw - an in depth examination

    I'm sorry for the off topic post but I must say that I'm truly impressed by your ability to adhere to the copyright terms attached to the FL1 standard. It is especially worth mentioning in the context of the 0.25lx figure. I applaud your willingness to protect the confidentiality of this...

    The Real Reason for Throw - an in depth examination

    It is reflected but the ambient light level at the Sun may make it a bit hard to see. I think though that if the observer is comfortable with what they consider the room temperature there, the illumination shouldn't also be a problem ;) As far as I know the stars other than the Sun are usually...

    The Real Reason for Throw - an in depth examination

    The FL1 standard discusses the distance at which the target is illuminated with the predefined illumination (0.25lx) so it is not the illumination which is measured but the distance. What I was writing about was still the distance but taking into consideration also the amount of light that goes...

    The Real Reason for Throw - an in depth examination

    I'd have to check but it looks like what you propose doesn't really need any plot. If we define 0.25lx at 1m as the reference, the throw definition you propose would be simply a square root of the beam distance. If for example the beam distance is 100m the throw is 10m - at 100m the target...

    The Real Reason for Throw - an in depth examination

    I like the definition in the standard but I agree with saabluster that it can be misleading. I think no one previously mentioned that measurements in the definition performed at the target may be problematic. The light has to go back to a person holding the flashlight so as I understand it the...

    The Real Reason for Throw - an in depth examination

    Thanks for this information. I didn't know that such a standard finally appeared :) If I understand correctly, to determine the "beam distance" (i.e. our "throw") they simply measure the maximum illuminance (at 2, 10 or 30 meters) and use the inverse square law to determine at what distance it...
