I think Fenix over drive in the Turbo mode, as I told you before, it happened to me on the Fenix P3D, 30 min in Turbo, the plastic dome lens (what it called ah?) cover the LED will be over heated and become brownish. Though the die may be a bot yellow also, but the dome lens will kill alot of lumens. Take a photo may, for us to see?
So for Fenix owners, check your manual, it says don't run on Turbo for more than 10/15 mins. (Silly clause

) only found out after I burnt the P3D. (it was fixed and now become the world's most Yellowish Fenix

, that is a long story the course of fixing the light)
Yeap, I remember your P3D story. I'll have a photo soon. The TK40 suppose to have thermal protection though, but it looks like it'll only protect the LED from being totally damaged rather than partially now.

Actually i'm contemplating to get myself TK40. I'm already got the 12pcs of Imedion AA together with Maha MHC9000. Along the way I already spend most of the budget to surefire M3 and M3T. The M3 already received but the M3T still no news.
pseudoblue, pls give us some more report about the LED after somemore usage. I like the beam but that night sniper's m2xc4 (is it the correct model?) really got me on the built quality. maybe i should get that also.
However L1 mini also quite nice and also .......
Let me poison you with the Quark Turbo AA^2 with XPG LED!!!
EagleTac M2XC4 was impressive and I think it had the furthest throw compared to all, even the TK40. The new clicky feature allows the light to be completely shutoff which is great. The UI is also easy to handle, and battery management for 2x 18650 also seems good. But you need to hear more from sniper69, he's a heavy user of the M2XC4 neutral white and he said it was very good. Strinq also can give feedback about his cool white version.
Here's what I think about the TK40... I've put it in spoiler cause it's abit long

Let me know if you decide on the TK40.

Regarding the TK40. It's up to you if you are okay with 8 AA batteries, preferably dedicated for the TK40. For me it is fine, but to some people it may seem to be a little too much to manage and I can understand why. Especially when you need to make sure they are about the same voltage everytime before you slide the carrier into the light. I'll be very honest here..
- Max time I've used on high (277lm) was 45 mins+. The light felt a little warm. So I'm guessing it can go up to another hour or two before it gets hot to the touch.
- For medium (90lm), I've used for 3 hours continuously, the light didn't feel warm at all. So I'm guessing it can run until the batteries are depleted.
- Turbo, well we know now don't run more than 10 mins, unless there's some sort of wind to cool the fins. It was hot to the touch, but you can still hold it.
After I found out yesterday abt my LED, I did several 1-2 minutes tests on turbo at different times. LED dies are the same still, light functions are all still okay.
From my personal experience so far, the TK40 is good for any general purpose, e.g house blackouts, photography light, night walks, 1-2 days camping, hunting, work inspection, perfect ceiling light, etc. Has a very nice floody beam, because of its brightness, makes the light sorta of a thrower. It's easy to operate, nice smooth knurling, anodizing are alot tougher. After hours of usage, for several days depending, just charge the 8 batteries and pop into the light again. Simple right, it's great for any of these.
But it's not exactly, I'll use the word "user friendly" if you are gonna use it for something more:
- Long backpacking/camping 4-7 days: You don't necessarily need a super throw light for this and imagine carrying extra AA batteries (8, 16, 32?).
- Security Guard, Law enforcement: You'll be using your light everyday for hours, can be mostly on high. Charging 8 batteries or more everyday or alternate days can be tiring.
- Tactical situations: You don't have quick access to the highest and lowest modes immediately, you need to cycle thru it. Cycling thru the mode you want can be immediate or up to 8 seconds.
- Quick battery change; You'll need to insert batteries carefully and correctly. If you're in a hurry, especially if you need to run 4AA on emergency quick, you might end up putting in the wrong parallel slot, no danger though but no light! Then end up opening the light again. It's actually quite easy but these things do happen.
So there you go, these are some of the practical things I felt about the TK40 when I was using it. I still like the light though, the beam is very nice, though I fall under general purpose. It's just feels nice to hold it
