Fenix RC40 (6000L) | Fenix TK75 (4000L) | LD75C (4200L)

Review of Fenix RC40 2016 with TK75 4000L and Fenix LD75C 4200L

Posted by : kj75 (CPF) 

Lately, I got in the most impressive flashlight that I had my hands-on: the new Fenix RC40-2016 version. This impressive, big torch has an output of 6000 lumens, that is an increase of about 2000 lumens compared to my actual output-king, the Fenix LD75C. Above the impressive output, the RC40-2016 should reach a distance of 730 meters too. There are more interesting features, that I will show you in this review, including beamshots compared to other big lights. Let’s kick off!

Unboxing:

The RC40-2016 comes in transparent plastic case, that we earlier met at the TK75. Fenix “wrapped” an attractive carton around the case, that shows the RC40-2016, the most important specifications and some “action-pictures”. The box has a lot of storage-components to restore the chargers, spare part and so on… The box is complete, except a holster. You should carry the RC40 by using the shoulder strap. Overall, a neat and complete carrying case! Scroll down to have a look into the box!

complete: two chargers, a lot of spare parts, and so on. Ready to go!


Impressions:

If you’ve ever had your hands-on to a Fenix, you will recognize this: There’s almost no flashlight that feels like a Fenix. The RC40 feels solid, long-lasting and is excellent manufactured and finished. Because of the large proportions this isn’t an all-day torch that you will carry every day. Although the RC40 has a heavy head (filled with many emitters), the light is balanced well. The RC40 has Fenix-looks: you will recognize details of the TK- and the other RC-members. Personally, I like the design, that gives the RC40 an impressive appearance. The machining, anodizing, and the used materials are of good quality. I couldn’t detect any flaws in the reflectors and the 6 XM-L2(U2) led are well-centered and have their own and typical position. The RC40 has total three holes in the head where you can screw-in the ring that is needed to add the shoulder strap. So, you can choose your favorite position. Also inside the tube it looks ok: No glue of solder rests, and gold plated contacts for the rechargeable battery-pack. At the lights’ back we see four (blue) indicators, a dc-in and an usb-out port and a little button. The little button is only for a power-check and can’t be used to turn the light on or off. All parts on this light feel durable, so overall, we can say the RC40 has very good quality. Please scroll down to view a lot of impression-pictures!

User interface:

Because the RC40 is a heavy torch, the shoulder strap is needed when using the light for longer time. The RC40 needs a “big hand” because of the dimensions and the thick tube. The light is controlled by two button below the lights’ head. Personally, I would prefer stiff structure and illuminated of glow in the dark buttons that are easier to locate in total darkness. But the operation works fine and without defects.

Charging-job can be done using the power adaptor or the car-charger. It works simple, and the progress will take about average 3-4 hours when the cell has totally run out of power. In future, I would like to usb-charging, because the risk of forgetting the special charger….The blue leds will blink clockwise during the charging-progress until the RC40 is fully charged. The discharging works also fine, you can use the RC40 to recharge your cellphone for many times. The indicators will blink during that progress too, starting at the remaining power level. For example: when the battery is below 50%, only two indicators will blink during the progress. To check the actual voltage (in standby-mode), simply press the little button next the charging port.

Back to the buttons now: The right button is needed for switching the RC40 on and off and for all normal modes. Pressing the right button for about one second will activate the light in last used mode, after that, you can cycle though the modes by short presses. Again a longer press will shut the light off. The left button is only for Strobe and SOS. Pressing the left button will give direct Strobe; at Strobe mode you can cycle through Strobe and SOS by short presses. In my opinion, Fenix could better use the left button for direct Turbo, a function that’s missing now. If that, a quick double press could be used for instant Strobe. I really hope Fenix will fix this in future!

Summarizing, the charging and discharging works fine, the interface also, but I would like to see some extra (instant) modes/functions.

Modes:

The RC40 has total five normal modes, starting at ECO > LOW > MID > HIGH > TURBO. ECO starts at 45 lumens….I would like to see a lower mode. For the rest, the mode-spacing is good. The light has two special modes: STROBE and SOS. There’s one instant mode: STROBE will be activated directly when pressing the left button. Like the TK75-2016, the RC40-2016 has a lockout-mode: Press both buttons together for about 3 seconds to (de)activate. I’m happy with this feature, because it’s really needed during transport.

Overheat protection:

When the temperature will get about 65 degrees Celsius, the RC40 will automatically lower the output until temperature will be less than 65 degrees. This means that the light will not full stepdown, but will go back in actual mode when it’s cooled down.

Size comparison:

To show the impressive dimensions of the RC40-2016, I’ll show you the light side-by-side to the LD75C and TK75-2015 brothers.

the tails: Fenix LD75C, Fenix TK75-2016 and Fenix RC40-2016


Tint:

A good coolwhite tint to the RC40 here: Compared to the TK75-2016 you can see the spill is less blue. Clearly noticeable the LD75C has a greenish tint. This was a pre-production sample, so maybe later batches should have about the same tint as the other lights.



Beamprofile:

Fenix has angled the six leds in a special way. This creates a big hotspot and corona and also a lot of spill. The spot is intense, this will give the RC40 a nice mix of throw and also enough flood. This beam is perfect for search jobs. Although this beams have their typical shape (which is because of the six reflectors), I couldn’t detect any defects. No PWM at any mode. Please scroll down to view the beamshots I took. They show the impressive output of the RC40-2016!

Beamshots:

Let’s start here by showing the RC40’s profile when shining at a white wall. Because of the big output I adjusted my shutter time a little. Distance to the wall about 0,75 meters.

Camera settings: ISO100, WB daylight, F/2.7, 1/200 sec, 35mm










GIF-picture:




Going outside now: I’ll show the output and the profile of the RC40 here in the forest and also at the field. To show the impressive output and beam, I took the LD75C and TK75-2015 (that are impressive lights too) also with me. Starting in the forest!

Camera settings: ISO100, WB daylight, F/2.7, 4.0 sec, 35mm

Conclusion:

This is clear to me now: The Fenix RC40-2016 is the most impressive lights that I ever had my hands-on! The combination of big throw and output gives the opportunity to light up a complete area. The RC40-2016 isn’t a light to use in and around home…I don’t use a powerful light like this in the neighborhood, but in the field or forest, you can have fun!

The quality and the finishing of the RC40-2016 are excellent done. This light will last for many years. For me, there are some wishes about this big torch: I would like to see a better low, some extra modes (especially instant-turbo) and usb-charging.
I can recommend the RC40-2016 to all who need a wall of light for search jobs or special tasks. Good to know that you carry a good powerbank too, that will charge your cell phone many times in emergency falls. And while carrying a torch like this, you don’t have to be afraid of the dark!

Sections
Ⅰ.A brief introduction of ANSI/NEMA FL1-2009 Standard
Ⅱ.Why was it created?
Ⅲ.Who approved the standard?
Ⅳ.What does it mean to consumers and distributors?
Ⅴ.The descriptions of the contents
Ⅵ.How will Fenix use it?
 
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 standardized 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 for short)
National Electrical Manufactures Association (NEMA for short)
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. The result is
reported in lumen.
Purpose: 
To provide a procedure for the measurement of the quantity of overall light energy emitted by the device.
Power resource: 
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. 
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 light output claim is made, a specific battery type and chemistry shall be recommended with the package. 
The batteries recommended by the manufacturer are to be used for testing.
Procedures:
Devices are to be mounted or held against an external port adapter or placed inside the sphere. Exposure should be set to produce test equipment manufacturer’s
detector saturation level.
Results:
Light output is the average lumen value of the 3 samples.
 
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.
Purpose:
To determine the amount of time elapsed (under continuous operation) at which the device’s light output reaches a level when users will commonly replace the batteries.
Conditions:
If the device offers multiple output levels, the runtime will be measured at the maximum level or as otherwise identified.
Procedures:
The initial reading is taken at 30s of continuous operation when using a luxmeter, ensure that the light is operated continuously without any off time.
ANSI/NEMA FL-1 standard
 
3.Beam Distance:
The distance from device at which the light beam is 0.25 lux.
Results are reported in meters.
Purpose:
To provide a procedure 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.
Procedure:
Place the luxmeter at a test distance of either 2 or 10 or 30 meters from the lens of the device to be tested. Use the luxmeter to identify the brightest point of the beam pattern and record the highest indicated value.
 
Final calculation:
To determine the beam distance, the Inverse Square Law formula is used:
√( peak beam intensity (cd) /0.25 (lux)) = Max Beam Distance (m)
 
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.
Purpose:
To provide a procedure to determine the peak beam intensity, reported in units of candela, of the device’s beam pattern within 30s to 2 min of operation.
Procedure:
Place the luxmeter at a test distance of either 2 or 10 or 30 meters from the lens of the device to be tested. Use the luxmeter to identify the brightest point of the beam
pattern and record the highest indicated value. Results are reported in candela. 
Measurements shall be taken 30s to 2 min of turning on the device.
 
Final Calculations:
Surface light intensity (lux) x distance (m)2 = peak beam intensity (cd)
 
5.Impact Resistance:
The degree to which a portable light resists damage when dropped on a solid surface. Dropped samples must not exhibit any cracks or breaks, and must remain fully functional in order to pass the impact resistance test.
Purpose:
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.
Drop Test:
Products are dropped with all intended additions: batteries ,elastic, tethers, hand straps, etc. 
Drop height for product samples shall be 1m minimum. 
When measured, all the requirements listed below must be passed:
 
Each sample is dropped 6 times using impact orientations that approximate a cube. 
Samples must be marked prior to the drop test in a manner that can assure that all 6 drop orientations are tested. 
Each sample must be released on each orientation of the approximated cube. Samples should be in the “off” position with batteries in place.
 
Passing Criteria:
Dropped samples must not exhibit any cracks or breaks visible with normal vision. 
The product must remain fully functional. 
Some reassembly is allowed provided that is done without any tool or replacement components. 
Cosmetic defects such as scuffs, scratches, rubs, abrasion will not be considered reasons for failure.
 
Impact Resistance Rating:
Test samples must pass a drop test from a minimum of 1m in order for the impact resistance claim to be made. 
Rating in excess of 1m shall be reported with values rounded down to the nearest whole meter.
 
6. Water Resistance:
Purpose:
To test whether the flashlight water resistance can satisfy the lowest requirements for the reliability.
Procedure:
All test samples shall function normally immediately after the test and 30 min after the test. 
Water ingress is allowed as long as the above conditions are met.
 
Water Resistance: 
There are three tests that measure water resistance:
 
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. 
In order to meet this target, Fenix was the first manufacturer to participate in the ANSI/NEMA FL1-2009 Standard in China. 
It will adhere to ANSI/NEMA FL1-2009 Standard with its products.
For instance, the ANSI Standard was introduced to E21, LD25, LD40 and HP20.
Later products continue to be line with the ANSI Standard.
 
A. In line with the ANSI Standard, Fenix tests the output and runtime.
 
Output Testing
 
Output Test: Devices are to be mounted or held against an external port adapter or placed inside the sphere. 
Exposure should be set to produce test equipment manufacturer’s detector saturation level.
Light output is the average lumen value of the 3 samples.
 
Runtime Test: The duration of time from the initial 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.
Ensure that the light is operated continuously without any off time.
 
B. According to the ANSI Standard, Fenix tests the beam distance.
 
Beam Range Testing
 
Beam Distance Test: To place the luxmeter at a test distance of either 2 or 10 or 30 meters from the lens of the device to be tested. 
Use the luxmeter to identity the brightest point of the beam pattern and record the highest indicated in value.
To determine the beam distance, the Inverse Square Law formula is used:
√( peak beam intensity (cd) /0.25 (lux)) = Max Beam Distance (m)
 
C. Fenix tests the peak beam intensity, abiding by the ANSI Standard.
 
Beam Intensity Testing
 
Peak Beam Intensity test: Place the luxmeter at a test distance of either 2 or 10 or 30 meters from the lens of the device to be tested. 
Use the luxmeter to identify the brightest point of the beam pattern and record the highest indicated value. 
Results are reported in candela.
Measurements shall be taken 30s to 2 min of turning on the device.
 
D. Fenix tests the impact resistance according to the ANSI Standard.
 
Impact Resistance Test:
Samples should be in the “off” position with batteries in place. 
Each sample is dropped 6 times using impact orientations that approximate a cube. 
Each sample must be released on each orientation of the approximated cube.
Test samples must pass a drop test from a minimum of 1m in order for the impact resistance claim to be made.
Dropped samples must not exhibit any cracks or breaks visible with normal vision. 
Cosmetic defects such as scuffs, scratches, burs, abrasion will not be considered reasons for failure.
 
E. With the ANSI Standard , Fenix tests the water resistance.
 
Water Resistance Test:
All test samples shall function normally immediately after the test and 30 min after the test. 
Water ingress is allowed as long as the above conditions are met.
 
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. 
Only the products which completely meet the ANSI Standard and its internal standards can be called Fenix products.
 
A. Shakeout Test
Shakeout test: To provide a procedure to determine the scratch-resistant and wear-resistant abilities of the surface of flashlight.
 
B. Bending Test
Bending test: mainly use to test the bending degree and the strength of wires.
 
C. Salty Spray Test

Internal Temperature Testing
 
Fenix has introduced the ANSI Standard to its new products. All technical parameters of the products, such as E21, LD25, LD40 and HP20, were produced in line with the ANSI Standard. As a result the output and the runtime figures have become much more accurate and scientific. Later products have been produced in line with the standard to meet the international needs.
 
3. Fenix has introduced the ANSI Standard to its product packages.
 
Product Packaging Markings
 
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.
