По умолчанию Pictures, Impressions - Fenix TK76 (2800lm, 50800cd)

Fenix TK76 arrived few days ago.. now this is the only one TK76 in my country. I made some photos and I would like to share my impressions. I hope you like it.


About TK76

- Uses two Cree XM-L2 (U2) LEDs and one Cree XM-L2 T6 neutral white LED with a lifespan of 50000 hours
(Flood lights angle: Cool white: 120°, Neutral White 60°)
- 222mm (Length) 55mm (Diameter) 100mm (Head length) 77mm (Head Width)
- 800-gram weight (excluding batteries)
- Digitally regulated output - maintains constant brightness
- Reverse polarity protection guards against improper battery installation
- Intelligent thermal control to protect the flashlight against over-heat
- Tri-color displays indicate the running level and the remaining power with low-power warning
- Anti-roll and slip-resistant body design
- Independently-controlled lighting heads permit easy and fast operation
- Instant Turbo activation for immediate illumination
- Made of durable aircraft-grade aluminum
- Premium Type III hard-anodized anti-abrasive finish
- Toughened ultra-clear glass lens with anti-reflective coating and quality PC lens

Tech specs (ANSI NEMA FL1)

Output
Single head: 7lm (200h), 135lm (33h), 350lm (11h30m), 933lm (3h30m)
Three heads: 20lm (66h), 420lm (11h), 1100lm (4h), 2800lm (1h10m), SOS (420lm), Strobe (2800lm)
Distance (max): 420m
Peak Beam Intensity (max): 50800cd
Weight: 800g (excluding batteries)
Impact Resistant: 1m
Waterproof: IPX-8, underwater 2m
Accessories: Lanyard, O-rings (2pcs)

Notice:
1. The above-mentioned parameters (lab-tested by Fenix using ARB-L2 18650 rechargeable Li-ion batteries with the intelligent thermal control off) are approximate and may vary between flashlights, batteries and environments.
2. Since the lighting effect varies among the three LEDs of the three individual heads, the output and the runtime of a single head may vary and the parameters shown above reflect average values.
3. The flashlight has various intelligent protection functions (e.g. intelligent thermal control), therefore, the runtime in the table is the accumulated time without the protection functions, and the actual runtime will be longer.



There are four indicators behind each lighting head. When the light is working normally in the general mode, the indicators will be blue. The number of the indicators illuminated shows the head’s current brightness up to a maximum of four.
There are five buttons on the neck of the flashlight. The upper three mode switches control the three individual heads for flood light, spot light and flood light (neutral white) from left to right respectively. The lower yellow button on the left with a sun mark is the Instant Turbo mode switch, while the red button on the right with a power source mark is the power switch.


On/Off

1. To turn on /off the three individual heads, press and hold the related mode switch button;
2. A single press on the power switch button will turn off all the lighting heads whether one or more lighting heads is on; another single press will turn on all of them.

Change brightness level

With the lighting head on, a single press on the related mode switch button switches the light between Turbo -> Low -> Mid -> High -> brightness levels.

Strobe and SOS

1. For Strobe mode, press and hold the power switch button for 1 second, and the three lighting heads will flash between 6Hz and 15Hz every two seconds.

2. For SOS mode, press and hold the power switch button for 3 seconds; the three heads will flash by the SOS signal.
Under the condition o f Strobe or SOS, a single press on the power switch can return the flashlight to the general mode.

Instant Turbo mode

Press the Instant Turbo mode switch button to enter into Turbo mode. The three individual heads will run at the highest levels with the remaining power. Release the switch, the flashlight will return to the former brightness level. Press and hold the switch for over 5 seconds and it will continue to run at Turbo output until a single press on the Instant Turbo mode switch button or any other mode switch button returns it to the last-used brightness level. A single press on the power switch button will turn off the flashlight.

Power indicators

Double press the middle mode switch button for the searching head and the indicator light will turn purple while the other two indicators will be off. In this case, the flashlight enters into the power display state and it will automatically return to the normal working condition after 3 seconds. Under the power display condition, the flashlight will continue to run at the current output level and the switch buttons can work normally. Flowever, the power indicators will be off when pressing the switch buttons.

With advanced circuitry, the TK76 will remember the last-used brightness level of each lighting head (not flashing modes) the next time it is turned on.Whether it is on or off, the light will enter into strobe or SOS mode if the power switch is pressed and held or it will enter into the Turbo mode with a press on the Turbo mode switch.

Intelligent over-heat protection

As with any high-output LED flashlight, the TK76 builds up heat when operated at higher brightness levels for extended periods. For your safety, the light will downshift to avoid overheat. When the temperature is lower, it will automatically reset to the current brightness level in full power; a single press on the Turbo mode switch will allow the flashlight to continue to work in full power.

Intelligent low-power warning

The circuit is programmed with a low-voltage protection function. If low voltage is detected, the indicators will turn red and the foremost indicator will blink to indicate that the power will not support the light to continue to run at the current brightness level. If the voltage is too low, the light will automatically downshift to a lower brightness level and the indicator will turn blue again. If low voltage is detected in the Low brightness level, it will turn solid red and then blinkto remind you of battery replacement. To ensure normal use, TK76 will not turn off automatically and will work until the batteries run out completely.

Intelligent low-power protection

1. Before turning on the flashlight, if the remaining power cannot support the flashlight in the last memorized level, the flashlight will light up at the lower output level instead of the last-used one to ensure the flashlight can be successfully activated.

2. When using Instant Turbo, the flashlight will enter into the highest output level that the power can support. If the remaining power can not support the three lighting heads to rim at Turbo output simultaneously, then the running output may be lower than the previous level. Battery Specifications


My impressions,

Pros

+ High quality machining, very solid, strong construction
+ Very nice anodizing as always from Fenix
+ Perfectly centered led (spot)
+ Clean reflector, lens surface, no dust etc
+ Very good beam quality no rings etc.
+ Extremely wide spill/flood lights without any problem (eg. rings)
+ Spot light: relative small hotspot with narrow spill, but excellent throw, seems to me this is more powerful than ~50000cd (but I don't have light meter)
+ Very well lubricated threads, o-rings
+ Strong battery holder (same as TK75)
+ Well spaced modes
+ Hidden strobe and SOS mode
+ No pwm or other irritating flickering etc, all modes perfect
+ No buzzing sound, all modes perfect
+ Battery/mode indicator leds (blue leds are spectacular in the night)
+ Excellent reaction time (switches)
+ Separately switches for all leds and instant turbo mode
+ Excellent heatsink
+ Tripod adapter (thread)
+ I like the design. For me "a flashlight from Star Trek movie"

Cons

- nothing significant (maybe the price)

Other comment

- Maybe the weight is too much for some peoples, ~1kg with four 18650 batteries.
- The tint is not bad, but three neutral white leds would be better
- Too big difference between two flood and spot light

and now the pictures.. if you need higher res pls click image, more photos coming soon, incl beamshots!
