Fenix UC01 Vs Nitecore Tube Comparison Video for India LED Torch India


POSTED BY, Username: Budda from Italy

Fenix UC01 It’s a keychain light, with integrated li-po battery, micro usb charging port, battery charge indicator. It shares some features with the Nitecore Tube and because of that, I’ll compare the UC01 to the tube.

Fenix’s specs:

•Utilizes NICHIA high-performance LED with a
•lifespan of 50,000 hours
•Built-in Li-polymer battery
•Micro USB direct charging
•62mm Length x 22.5mm Width x 10mm Height (2.4×0.9×0.4 in)
•13 grams weight (0.5 oz) excluding key chain
•Spill beam angle of 102°
•Micro-USB charging, built-in protection circuits against
over charging and over discharging
•Stainless steel side switch for easy and convenient operation
•Digitally regulated output maintains constant brightness
•Intelligent memory circuit memorizes the last-used brightness level
•Battery level indicator
•Light body made of environmental PC materials
•Key chain made of zinc alloy, white nickel plated of the surface

It comes in a small plastic and cardboard box, with the light in plain sight. The specs on the back of the box.

Inside the box: a warranty card, the instructions (in many languages), some commercial material and finally… the little blue UC01.

The UC01 is a nice little light. The overall construction is simple but classy and sober, especially when compared to the tube that has a more eye catching look. On one side there is the Fenix logo with a nice X for adding contrast, the other side is just plain blue plastic.

The electronic switch is under a grey plastic cover. It is easy to find it because it sticks out, but it’s less grippy compared to the rubber one of the tube. It is more soft than the Tube one.
The UC01 has on the bottom some anchoring points for lanyard or keychain staff. The UC 01 it comes with the lobster clip installed.

The UC01, as the tube, has a horn shaped end to protect the led from damage during fall and carry.

The thickness is a bit more on the UC01, but nothing relevant.

It is a bit longer than the Tube.

However the difference is very little: 62×22.5 mm for the UC01 vs 56×21 of the Tube

The Tube can be took apart removing the screws, but I don’t see any screw on the UC01 so I think it’s kept in one piece with glue or by pressure.
With another widely owned keychain light: the Astrolux A01.

Click once to turn on the led battery indicator (green = charged, red = low charge, red flashing = less than 20% charge), it stays on for 3 seconds.

Keep pressed to turn the light on at the last used mode. Press to cycle to the modes in this order: low, mid, hi, lo, mid… the light has memory mode.
Keep pressed to turn the light off.
When you charge the light, the led battery indicator will be red, when charged it turns green. According to Fenix it will take up to 2 hours for fully charging the UC01 with a standard USB port, and recommends to charging every 2 month for insuring the best performance.

Beamshot: 1 meter from the wall
The blue UC01 has an opaque plastic, so no light will pass through the body of the light for the blue version. The pink one instead has clear plastic.

Fenix UC 01

Nitecore Tube

The UC01 is much more flood than the Tube. This means less throw (UC01 13Cd, Rube 80Cd) but better close range illumination (all the application where a hotspot is less desirable, such as illuminating your working area, reading…).

The tint seems cooler for the UC01, a bit on the blue side.
Also, no PWM at naked eye for each level.

Runtime and output Test:
With my ceiling bounce setup I found the UC01 to have the same output of the Tube, around 50ish lumens. Given the very high error at low measurement of my setup, I’ll stick to the 45 ANSI rated lumen, which I consider to be true.

Great regulation at Hi level. The other levels were not tested.



The Fenix UC01 is a well built keychain light, with a classy look.

The 3 levels are well spaced and regulated. The increased size (few millimeters) is compensated by increased runtime.

I like the battery indicator, it’s easy to read, and when charging isn’t painfully bright (as the one of the tube is).

The micro USB charging port for the integrated battery is always a nice feature. Many led keychains work with button cells: low runtime, output and expansive to replace.

With the integrated battery you get more runtime, and you can always charge them on the run with the widely diffuse micro USB port.

I carried for some time the Tube and I found it sometimes on in my pocket. I believe this also will happen with the UC01 since the pressure for activating the switch it’s lesser and the switch protrudes. If your carry system is prone to turning the light on (you have other items in the same pocket, you press your body against the light), I suggest you to put it in low mode.

By doing this, it will require many accidental activations to drain completely the battery.
For activating the light there is a delay of less than 1 second.

I appreciate the lack of visible PWM.

I red some users complain about the bluish tint of their UC01. My sample is a bit on the blue side.

A pure CW tint would be an improvement, and a NW tint would be even better (IMHO).

The price is reasonable, and is really a bargain when you find it for sale with a special discount.

In simpler terms, like the various other commodities in India and abroad are authenticated, measured and tested in order to maintain their standard quality, torches around the world have their mark too. Fenix being an International brand thats spread across the globe are standardised with the ANSI Mark (American National Standards Institute).

To have a clearer understanding, here are few examples for various commodities:

ISI MARK Indian Standards Institute | Products deemed for safe consumers use.

AGMARK AGMARK | Agricultural Product/produce
BIS BIS HALLMARK | Purity of Precious Metals like Gold & Silver jewellery


ANSI ANSI (American National Standards Institute) | ANSI represent more than 270,000 companies, professional societies, trade associations, government agencies, and consumer and labor organizations. ANSI lobbies for over 30 million professionals and covers nearly every industry across the globe


ANSI / NEMA FL-1 Standard


ANSI Standards, Fenix Torches in India   


Fenix Has Implemented the ANSI Standard for measuring performance and quality across our complete product range. ANSI Standards refer to: 








1. A brief introduction of ANSI/NEMA FL1-2009 Standard

2. Why was it created?

3. Who approved the standard?

4. What does it mean to Consumers and Distributors?

5. The descriptions of the contents

  • Light Output
  • Runtime
  • Beam Distance 
  • Beam Intensity 
  •  Impact Resistance
  • Water Resistance

    6. How will Fenix use it?

    • In line with the ANSI Standard, 
      • Fenix tests the output and runtime.
      • Fenix tests the beam distance.
      • Fenix tests the peak beam intensity.
      • Fenix tests the impact resistance
      • Fenix tests the water resistance.
    • Fenix carries out other tests.


    Ⅰ. A brief introduction to the ANSI/NEMA FL 1-2009 Standard

    American National Standards Institute (ANSI for short) was established in 1918. It is a non-profit non governmental standards institute.

    ANSI is one of the five permanent members in International Standardization Organization (ISO for short) as well as one of the four permanent members in the

    International Electrotechnical Commission (IEC for short). It takes part in 79% activities of ISO/TC and 89% activities of IEC/TC. ANSI is a member of COPANT and PASC respectively.

    ANSI is the potential national standards institute and actually it has turned into the national standards center. Various standardizing activities have connections with

    it. In the meantime, the ANSI Standard has been voluntarily adopted.


    Ⅱ. Why was it created?

    For a long time, there had been no standardised tests or uniform rating systems for consumers to judge flashlight performance. Without any uniform rating systems, it frustrated the manufacturers who were working hard to make high quality lighting tools.

    The establishment of ANSI/NEMA FL 1-2009 Standard allowed consumers to compare flashlight performance. The standard provides a guide for consumers to rate and compare the claims on the packages for each manufacturer’s products.

    Distributors and consumers are more informed. Therefore, it is much easier for them to make the best choices for their needs.


    Ⅲ. Who approved the standard?

    American National Standards Institute (ANSI)

    National Electrical Manufactures Association (NEMA)

    Representatives from 14 illuminating companies, such as Princeton, Surefire, Petzl, Streamlight, Black Diamond and Duracell, etc. Representatives from flashlight users and flashaholics


    Ⅳ. What does it mean to consumers and distributors?

    The ANSI Standard helps the consumers know about the technical parameters of flashlights quickly which allows them to make a comprehensive comparison of various flashlights.

    It can provide a guide for distributors and end users to know more about the products and make the best choices for their needs. It evens the playing field for those manufacturers that participate. It’s important to know that adherence to these standards and reporting results is strictly voluntary. Many leading flashlight manufacturers are now adopting the standard.


    Ⅴ. Description Of Test Conditions

    The testing contents of ANSI Standard include light output, runtime, beam distance, peak beam intensity, impact resistance and water resistance:

    1. Output:

    A measurement of the total quantity of emitted overall light energy as measured by integrating the entire angular output of the portable light source. Measured in Lumens.

    To measure the quantity of overall light energy emitted by the device.

    Power resource: All tests are conducted with fresh batteries or fully charged batteries. Batteries used shall be of the same type and/or brand as of the product. The batteries recommended by the manufacturer are to be used for testing. .


    2. Runtime:

    The duration of time from the initial light output value (that’s 30 seconds after the light is turned on with fresh batteries) until the light output drops to 10% of the initial value.

    To determine the amount of time elapsed under continuous operation at every level.

    Conditions: If the device offers multiple output levels, the runtime will be measured at the maximum level & at every level.


    3. Beam Distance:

    The distance from device at which the light beam is 0.25 lux. Results are reported in meters

    To determine the maximum distance at which the devices is capable of producing 0.25 lux of light within 30s to 2 min of operation.


    4. Peak Beam Intensity:

    Peak beam intensity is the maximum luminous intensity typically along the central axis of a cone of light. The value is reported in candela and does not change with distance.

    To determine the peak beam intensity, reported in units of candela, of the device’s beam pattern within 30s to 2 min of operation.


    5. Impact Resistance:

    The degree to which a portable light resists damage when dropped on a solid surface. Dropped samples must remain fully functional in order to pass the impact resistance test.

    To ensure the structural integrity of hand-held/portable lighting devices under specified impact conditions. The test procedure provide specifications and methods that will ensure products meet a minimum standards of reliability as a result of impact testing.

    Drop test should be a priority to any other reliability tests, shall be 1m minimum.


    6. Water Resistance:

    Purpose: The flashlight water resistance can satisfy the lowest requirements for the reliability.

    All test samples shall function normally immediately after the test and 30 min after the test.

    Water Resistance measured in regards to:

    Resistance to Temporary Immersion in Water

    Resistance to Continuous Immersion in Water

    Resistance to Splashing Water


    Ⅵ. How will Fenix use ANSI?

    1. Fenix will strictly adhere to the ANSI Standard to measure the various fundamental features of its products.

    Fenix will spare no efforts to provide more reliable products and perfect services. The consumers can better evaluate, compare and choose their products provided that they know about the output, beam distance, impact resistance, water resistance and the runtime.

    It will adhere to ANSI/NEMA FL1-2009 Standard with all its products.

    In line with the ANSI Standard:

    • Fenix tests the output and runtime.
    • Fenix tests the beam distance.
    • Fenix tests the peak beam intensity.
    • Fenix tests the impact resistance.
    • Fenix tests the water resistance.

    2. Fenix carries out other tests:

    Besides the ANSI Standard and to allow for consumers’ various real life usage conditions, Fenix performs other tests set by itself, such as the salt spray test, bending test, vibration test, ultraviolet radiation test, etc. 
    • Shakeout Test: To provide a procedure to determine the scratch-resistant and wear-resistant abilities of the surface of flashlight.
    • Bending Test: Mainly use to test the bending degree and the strength of wires.
    • Salty Spray Test: Mainly use to test the corrosion-resistant ability.
    • Ultraviolet Radiation Test: Mainly use to test the changes of flashlight after it goes through the ultraviolet test.
    • Environmental Test: Includes the high temperature test and low temperature test, which are used to test the high-temperature-resistant and the low-temperature-resistant abilities respectively.
    • Vibration Test: To provide a procedure to determine the anti-vibration ability.
    • Switch Test: To provide a procedure to determine the lifespan of the switch and the resistivity.
    • Temperature Test: To provide a procedure to determine the conditions of the heat generation and the heat dissipation and the relevant temperatures, etc.
    3. Fenix has introduced the ANSI Standard to its product packages.
    Fenix now records ANSI test results on its product packaging to allow customers to quickly understand the product capabilities.
    4. Fenix has introduced the standard to the product manuals.
    Fenix has made some modifications to its product manuals. The modifications help the consumers to easily identify, compare and rate the flashlights. Fenix will continue to report the ANSI Standard of its later products to meet the international consumer needs.
    5. The description of the flashlight tests.
    • All tests are conducted with fresh batteries or fully charged batteries /energy storage devices.
    • 12V DC devices that are only tethered shall be powered with 13.8V DC using a power supply.
    • Peak beam intensity and beam distance are both measured by the same test.
    • To provide a procedure to determine the peak beam intensity, reported in units of candela, of the device at which the light beam is 0.25 lux within 30 seconds to 2 minutes of operation.
    • Batteries used for testing and claim substantiation shall be of the same type and/or brand as those offered for sale with the product.
    • If the product is sold without batteries and a peak beam intensity claim is made, a specific battery type and chemistry shall be recommended with the package.
    • Lab conditions shall be a controlled temperature of 21±2℃ and a relative humidity of 50±40%. The lab environment must minimize any redirecting of light that would affect the measurement outcome.
    • If the device offers multiple focusing or adjustable beam angle, the peak beam intensity will be measured at the maximum level or as otherwise identified.
