The individual parts as well as the lamp when assembled make a very high-quality impression.
Perfect anodizing and soft running, lubricated threads with O-rings are required. The lasered symbols and logos are perfectly executed. The reflectors are made of aluminum and the Fronabdeckung is genuine, specially coated glass.
The lamp should necessarily be operated by Fenix recommendation with four NiMH rechargeable batteries with at least 9000mAh.
Only with this power supply, the specified performance levels and durations can be achieved.
When using mono batteries Turbo mode can not really be used as the control electronics back on the TK70 after a few seconds in the "high" mode.
However, the "high" mode with 900 ANSI lumens is really bright and adequate for most situations.
Furthermore, it is also possible by unscrewing a portion of the battery tube even to use the lamp with three battery or batteries - the duration is then shortened accordingly.
The lamp has a full-blown electric torch and overall quite large and heavy.
A real men light up.
I personally like the same way. The size is about that of a Abflusspümpel.
The TK70 has four digitally controlled power levels and two Binkmodi which are served by two rubber-sealed switch. A flash modes is performed as an emergency signal with 900 ANSI lumens and more leisurely rate during the second high-frequency and runs at 2200 ANSI lumens and the optical self-defense is. After switching on the lamp starts in last operated mode, as long as the Enerieversorgung was not taken.
If the energy no longer for the chosen mode, the electronic system switches to the next lower.
A duration of 1 hour 50 minutes by 9000mAh NiMH batteries in Turbo mode make the TK70 particularly in Zusammspiel with standard mono batteries interesting.
In this mode, max be. 2200 ANSI (!) - Delivered lumens.
Through the ANSI measurement methods, the actual luminous flux is measured in a standardized test set-up, which comes from the lamp.
Most lumens specifications diverse manufacturers based in this case on the theoretically calculated luminous flux of the LEDs installed under the most favorable conditions and in disregard of life.
That is pure nonsense and they ought not to be able to get an idea of the real light output can be used as well to any comparison.
In practical use, 2200 ANSI lumens are exorbitant bright. Really damn light!
When I previously tested the lamp near a farm, the rooster began to crow there suddenly. The thought probably the sun is going up again.
The beam is fairly balanced and very well usable in practice.
Wide Inge excellent Nahausleuchtung with a not too small spot area for distances up to 720m.
It should be noted yet that the Turbo mode has to pay an enormous waste heat over its aluminum body lamp in particular. The grease in the threads of the pipe joints reduces the heat flow very difficult.
To dissipate the waste heat using the battery tubes I have therefore the fat removed and replaced with Arctic Silver 5 thermal compound.
Now the heat is distributed more evenly over the whole lamp and it is a total of just over warm.
The Fenix TK70 meets exactly my expectations at a reasonable flashlight and I can highly enough to others.
