fenix L2D, trouble in paradise

[mimis]

ok, there was certainly a problem with my L2D runtime in turbo mode (35mins and sudden fading to 1/3 of initial output) and so i mailed fenix-store for some answers. Of course they suggested i'd send it back on my own postage fees, so i figured what the heck, i'll order a new one with not much higher cost. And guess what, new L2D just came, tested them out in the cold (7oC) side by side old and new one, and yep, they acted as real twins, sudden dimming at the same time, less than 30sec time gap!!! The light bodies are only tepid at hat point, overheating regulation can't be an excuse.. What's happening guys, i couldn't possibly be twice that unfortunate with technical defects! where's the claimed 150mins turbo run?

I strongly suggest to ask here : LED Flashlights

Surely runtime depends on what batteries you are using - what batteries are you using?

Hi mimis,

While I can't say what's going on there, I can mention one thing: Just because the light bodies are only tepid does not mean that some of the internal components are not overheated. (Look up "thermal resistance" for more details.)

With that said, I don't think that the L2D even has thermal shutdown protection. As another poster has said, it might be your batteries.

If you do diagnose what's causing this, please post the results. Thanks.

So I actually gave a helpful comment before he even started the other thread - if he'd bothered to reply to me rather than starting that new thread he'd have had the answer sooner (I'd guessed he might be using the alkalines they are supplied with).
