standard 'out of the box' fix . . .

I love it!

Sorry if I offended my flashlight brothers and 4Sevens. The problem has been resolved, I made my apologies, and now it is time to move foward. I am done with this thread. :)

Glad it worked out for you in an acceptable manner.
Most of us knew it would. :twothumbs

We weren't offended :-)

I'm sure we'd all love to know what was wrong with the light and what was done to resolve the issue though.

Could you let us know how if it was resolved? Did they send you a new light or did you find a fix?

Thanks!

UPDATE: The flashing is gone, but a new and more troublesome problem has developed. When I switch the light to Turbo, the head is warmish/hot in 10-15 seconds. Literally 10-15 seconds! Also, the color of the light goes to a bluish/purple and is not very bright (relative to Turbo). The space underneath the lens but above the emitter gets "foggy"! I had a light once where I accidentally touched the reflector and tried cleaning it with a microfiber cloth. If that has happened to anyone then you know how bad it looks. It looks like wiping a mirror with cooking spray. So I shut the light off and after a moment the reflector and lens go back to perfectly clean and clear.
4Sevens cust support is sending me a new unit. lol, when I told the CSR what you just read I think I scared him! :eek: Nevertheless they took care of me. I am beginning to think that if this light is a one-in-a-million flukes, then I should play the lottery, win it, and buy the entire 4sevens line!

To me, that sounds like the LED wasn't heatsinked properly. LED's turning blue is usually caused by 2 things: Overdriving, and lack of heatsinking. I've done both on purpose, and the fogging is another hing that happens. I did that with an XR-E, though, so that was due to the epoxy holding the main "lens" being overheated (2.5 amp @ 4.2volts through it = :poof:)

In other words, it was just a bad LED, or slight manufacturing defect in the light. It's nothing 4Sevens could have any control over, especially since they cannot open the packages to test them.

I'm glad to hear that it seems that everything has worked out.

Here's another possibility. We might have shipped you the low V head. If I could see the PCB I can tell instantly. Let CS know if you have any other issues.

Now that you mention that, it gave me an idea.

Would it be possible that the light could have some kind of protection against overvoltage (in the future)? As an example, you could have it flash a few times, then shut off, to alert the person that there is something wrong, and then in the manual (assuming there is one. I got my Quark secondhand, so I don't know if it comes with one), have a sentence or two explaining that if it flashes X times, it means that the batteries the person is using is supplying too high of voltage to the driver.


Just an idea. Not sure how/if that would work.
