Nitecore TM 26 Switch Trouble; Thrunite TN 12 (2014) Conduction Problems
Hi guys --
I've had my Nitecore TM 26 for about 2 weeks now -- I'm still on the first charging of the batteries. Unfortunately, it's developed a problem with the logic circuits of its switching functions. At times it cannot be turned off to go back into standby mode -- it will require the appropriate switch press (full depression of the switch) to be performed up to 8 times before the light will obey the request. I love it otherwise, so it's off for replacement or repair very soon to either the seller or the manufacturer. Has anyone else had trouble with this area?
As well, I bought two TN 12 (2014)s -- one in the cooler range that they offer, and the other in the warmer portion of the spectrum. The cool white version is fine, though its tailcap must be VERY tightly screwed on to insure contact with the middle section tube. (Note that I have NOT experienced any flickering once the tail is on tightly enough -- it's a good contact, thus far.) And, were this a review, I'd point out that the top two brightness levels are exceptionally close to each other and therefore, a bit of a waste -- it would be much better to have employed an additional low-medium level in say, the 40 lumen range instead of a high that's just below maximum. But I digress....
After a 3 week wait for the device to come back into stock and be shipped, the warmer version arrived non-functioning entirely, and with considerable dust/debris on the surface of the reflector. Some non-invasive experimentation with interchanging parts between the two units revealed that the problem was in the ability of the middle-section tube -- that which is positioned between the head and the tail-cap. It prevented either light from working, though surprisingly, if installed *backwards,* it makes decent contact and either unit will work. The problem here of course, is that this eliminates the utility of the light's clip in any practical set of terms. Something's going on with the manufacturing and the resultant dimensions of the contact points of that middle tube component, it seems.
To be fair, when I emailed them about the issue, Thrunite was quick to correspond toward trying to help me trouble-shoot. For the moment, a resolution is still in the works. Note also, that when I went to the Thrunite site today (6/21/2014), I cannot find warm-emitting version of the light listed at all.
Has anyone else had TN 12 woes? Remember, I also have one that works quite well, albeit with a slightly fussy tube-to-tailcap connection. -- I wouldn't turn away from the model entirely, though I feel that my Fenix PD35 is more reliable. Be well all!
