Actually the warmer colour temp in the TK35 is the yellowish green colour. Sometimes it could be pretty greenish, sometimes it could be ok. I have this in my other branded lights in varying degrees like RRT-2 XM-L, Balder BD-4, Sunwayman T40CS, Fenix TK70. All these $$ lights seem to like this tint, which is great for high output but not so good for low output. The TK35 clone is great, not bluish like the STL-V2/DRY in high (1A tint) but in low it's not yellowish+greenish, which looks to me very pale.
I'm thinking about getting one for modding, too. I like the host format and the extra button. Shouldn't be difficult to change it to a parallel setup and use an AMC7135 driver with custom firmware.
Got it from Ric....I have an order on the way (some replacement parts mainly a scratched bezel of another light) so i just tagged this together with it "FOC". :) http://www.cnqualitygoods.com/goods.php?id=1302
Other places are selling with shipping 23 bucks to 35 bucks! *faint*
Well I just got done testing the clone on high for runtime. It got 4 hours 34 minutes VS. 6 hours 26 minutes (I tested the TK35 again at the same time). This was with AW2900 batts.
The clone also ran much warmer than the Fenix during this test, even though it was actually a bit dimmer. PWM is much less efficient than constant drive. On turbo the clone runs cooler then the TK35, but I haven't measured runtime on turbo since the Fenix limits to 25 minutes at a time. The clone might run longer on turbo, don't know. Although dimmer.
Some interesting info from local forum (torch.pl, user 'greg', translated by me so sorry for any problems, link in Polish) for those with soldering skills. There are two R200 (200mOhm) resistors in the circuit. Solder another one to increase current to the emitter by 50%. His results:
before after
1. min 60 mA 90 mA
2. mid 200 mA 300 mA
3. max 930 mA 1400 mA
4. turbo 1940 mA 2900 mA
Remember to improve heat dissipation - there's poor contact with emitter PCB and radiator + almost no thermal paste.
Mine arrived in the mail today. Pretty happy with it, was a little disappointed with the lack of memory. Overall a good light, not as good as the real TK35, but at less than half the price, who cares. Maybe I can start down the modding path with this one. Anybody have any ideas (and some basic instructions) for a novice?
Not really, won't get the real Fenix TK35. I'd pay 30 bucks more for the Sunwayman V60C. Quite a bit better looking, magnetic ring and much lower lows, 3 x 18650 plus bigger front, ie more throw, much more runtime hence "flexibility".
As for the 820 OTF lumens provided by Fenix, it is a wee bit optimistic. Check out the relative figures from Selfbuilt (also following ANSI about measurement time after turn on), it is even lower than quite a few other lights. Relative comparison in the real world directly with other lights is best.
