    quark mini AA & CR123 users thread

    Does anybody know how to fix a Quark Mini 123 so that it actually works properly? The spring is far too weak to prevent the light from changing modes on me, and I got no response after emailing 4-7s customer service. The spring should be thicker, and the length of the spring (if it were to be...

    New website and online shop.

    This was two months ago, and nothing that has a "buy" option at the bottom of the product page does anything other than display a popup saying "coming soon." Any update?

    What makes 5mm LEDs last longer?

    How long have you had this 5mm light? The ones I bought from WalMart at two for $3 maintained their brightness for about 6 or 7 weeks. After that, they slowly dimmed to the point that the LED is only barely noticeable during the day and only bright enough at night to serve as a marker: usable...

    What makes 5mm LEDs last longer?

    I understand. The ones I bought from WalMart look nearly identical, on the outside, to the EliteLED bulbs you see in the images I posted. THEY ARE NOT THE SAME, YOU CAN BE CERTAIN. However, based on the ***** performance, I would not be surprised to learn that the WalMart bulbs that I bought...

    What makes 5mm LEDs last longer?

    I don't mean to drop in and have my post look like an advertisement, but I too once shared the frustration of being unable to find decent LED replacements for the incan nightlight bulbs that burn out every few months (or weeks, even). I was fortunate that I gave the following product a try...

    Panasonic Geolux LED flashlights. Anyone have more info?

    Found these by accident at: http://www.panasonic.com/consumer_electronics/promotions/geolux/geolux2.asp One of them uses a single CR123 battery, and the other uses 2xAA batteries. Eu

    Is there a difference in runtime between the two different RC-T5 lights you have? Eu

    Which one is YOUR best CR123 light ??

    I second the recommendation for the P2D-CE. I have the Cree P4 version, but I will get a Cree Q5 (or later) version sometime soon. The P2D-CE is very versatile and easy to pocket. I don't doubt all the good things people say about Surefire lights, but they are too expensive for what you get...

    4 Cree Light !!

    Mine doesn't. My Romisen RC-T5 operates as follows: Click -> 100% Click -> Off Click -> 50% Click -> Off Click -> Flashing Click -> Off Click -> 100% and so on.... If I leave the light off for more than a minute, it starts over from the beginning just like above, no matter what was...

    4 Cree Light !!

    I am also pleased with my Romisen RC-T5. The high level works reliably without any flickering regardless of battery source. I happen to be exclusively using 2 x 18650 batteries, but I am glad that the light accepts either four or three 123A primaries as well. I have logged about 6 hours on the...

    4 Cree Light !!

    I don't have any rechargeable 123s. I never saw the need, considering their expense coupled with their poor capacity. But my hunch is that with 3 x RCR123 there would be no flickering at first, due to the higher initial input voltage. :shrug: Eu

    4 Cree Light !!

    I can't say I quite understand, but I can say that the flickering (in my light) appears to be dependent on input voltage: 4 x CR123 = no flickering; 3 x CR123 = flickering; 2 x freshly charged 18650 = flickering; yet 2 x no-longer-fresh 18650 = no flickering. Eu

    My CR2 Ion Saga

    I used to have intermittent problems with flickering, but only on low. The simplest solution for me was to just turn the head a little bit more in the clockwise direction until better contact was made. One day the flickering just seemed to go away! I have always used the RS lube, on my CR2-Ion...

    4 Cree Light !!

    I have also observed this. I think there is something in the circuitry that distinguishes between various input voltage levels, so that when the light is in 50% mode there is flickering when the voltage is between about 9v and 8v. However, when I leave the light on 100% for a while with 2 x...

    Why aren't the Surefire lights way brighter?

    The original poster wanted to know why Surefire lights aren't "way brighter," and I think many good answers above explain why. But many of those who defend Surefire against all critics are simply emotionally connected to their past decisions: they bought Surefire lights back when there were few...

    4 Cree Light !!

    Thank you for doing this. I guess this means there is nothing "wrong" with my light (in particular). I was worried that the circuit might be faulty and would eventually fail to function at any level altogether. But it makes me wonder. My light does not flicker on high mode (= 100%) no matter...

    4 Cree Light !!

    I am using *fresh* Duracell Ultra 123A batteries and brand new fully charged protected button-top 18650 batteries from AW which I ordered specifically to use in this light. I cleaned all contact points and the problem remained. I am using the highest quality CR123 (fresh Duracell Ultra) and...

    4 Cree Light !!

    I don't know about the others who have the Romisen RC-T5, but mine flickers on 50% when using 2 x 18650 or 3 x CR123 batteries, but it does NOT flicker on 50% when using 4 x CR123 batteries. By flicker, I mean the output seems to hesitate here and there, a couple of times a second or so, which...

    4 Cree Light !!

    I also couldn't resist and ordered one. :sssh: I actually prefer the 50% setting for low, since to my eyes (with poor night vision) it will be like 25% of the high setting, and that's still a good level for use outdoors (since I don't ever expect to use this indoors). Although a 10% setting in...
