Re: The Quark lights thread! (Part 3)
You mean that Quark working voltage is 0.9-4.2V, and if i leave my Quark AA on low it drains the battery below overdischarge protection which is at 0.9V?
Or do you mean that it needs more than 0.9V, if it needs, how much is it?
I have not noticed this kind of behaviour in my Fenix LD10, i need to run a few tests with it....
I don't know about the working voltage of the Quark(or that many details at all), I just mentioned a problem I discovered on other multistage lights, and I guess that goes for all multistage lights(especially those with really really low levels). This is just an issue I remember when you guys brought up other "minor" issues. I don't remember at which voltage my light(think it was a L1D or NDI) but I remember that if I didn't turn the light off, it ran for a LONG time. But if I turned it off and tried to turn it on again, it refused. So the circuit needed more start up juice than it required to run the light. My thought was just that the runtimes could be very misgiving then(especially on lights that has REALLY low) since they will run a lot longer than it's actually practical(you can't turn the light on if it's off).
About the over discharge protection, I don't know if the Quark has that(I asked the same question in an earlier post). The 0,9 might just be the voltage the circuit requires to run the light and you will the battery down if you leave it?
And does the Quark step down in levels or does it just empty the battery and then don't work on low?
I think we could find a scenario for any light that isn't perfect. For those using primary batteries having them sucked completely dry is no problem. However, for those using rechargables that is a problem. I personally like having the light maintain the same level of brightness on any given level for however long it can. That can be seen as a weakness in a "survival" situation but in others it is a Godsend. I have a couple of Fenix lights that just basically drop down in level to the closest they can regulate. For instance, if I am using turbo and the batts can't maintain regulation anymore it drops down to medium or low. I don't have my Quarks yet so I don't know how they will respond.
Oh, I know, there are scenarios when it's prefered that you can't suck your batteries dry. I'm just nitpicking, and was bringing up an "issue" many people don't think about. Personally, I would prefer if I could chose myself to turn of the battery. It would be ideal if there was a mode that was direct drive, and it was up to the user to care for the batteries. But this is as said just nitpicking. Overall I think the Quark seems to be a terrific light.
