Package and content:

The lights box came packed well with a plenty wrap around and in a plastic bag

The light comes in a package with 2 sections one for the light and a small box with accessories

In the box is a plastic inlay with the light

It comes with:

remote switch with 2 o-rings to mount it,
USB cable,
handlebars mount,
2 adhesive stripes,
manual and warranty card

The manual is in 4 languages, but the text is very small and hard to read

Photos of the light

Beam color is neutral around 5000K with two Cree XML2 LEDs, the light has 2 beams comparable to car headlights with low and high beam

Teardown:

The light is easily taken apart, only the adapter plate for the mount is glued and screwed to the light

The front bezel is screwed with 3 small screws under it is the secondary optic and a rubber seal

The back comes loose when 3 screws removed, the outer part is screwed also with 3 screws

The PCB is screwed and glued with the plastic part, probably to seal the lights internals from water that gets past the USB covers

The LEDs are very good reflowed on a solid 2mm thick copper MCPCB, there is no shelf,
but it is pressed in the tube and make contact on some spots to the outer wall and the area where it is screwed
It would have been nice if some heat paste to enhance the heat transfer even more

The light has a hole for a lanyard

The light stands on the tail if it is used ceiling bounce in a tent or so

The light has an internal battery of 2 2600mA 2C low drain cells, that can also acts as a power bank
The battery can get charged with micro USB socket, I measured about 2.9Ah per cell 3.01-4.19V

The driver has 2 separate buck converters for each LED
the LED wires are short and thick

The light has a good sealing against water, even the screws on the back have o-rings

The secondary and primary optics are plasic

Driver and Battery

The light has 2 separate buck/boost converters no visible PWM in any modes, even falling water drops are draw a smooth line

The light keeps the brightness even with lower battery voltage
The light has a soft start and fades fast from one mode in the next

The lights surface is all aluminum except the tail section with the connectors
Even running at 1200 lumens the light gets 55°C warm but not hot

the light steps down when the battery voltage drops below 3.55V

I had the battery depleeted today
The light shuts down when the cells reach 3.01V

Then did a full charge
The build in charger charges with 1.5A

The measured capacity is 5.9Ah I would say than the LED display and electronics eat up about 100mAh
so the two 2.6Ah cells are charged from 3.0V to 4.19V with 2.9Ah

.

The mode spacing is good for a bike light, naturally it has no ultra low mode

relative Lux measurements:

4 static low beam modes
High 100%
High2 66.1%
Medium 38.8%
Low 15.6%

3 high beam modes
100%
52.2%
24.7%

The high beam has about 3500lux@1m measured at 10m

The light has a display which shows the remaining battery runtime and 2 symbols for low and high beam

Modding:

I added some heat paste between the tubing and the MCPCB

User Interface

Unfortunately the manual has absolutely no word about the user interface

I figured it out

.

A 2s press on the big power button powers the light on/off

The light has 8 modes
5 are low beam modes High—>High2—>Medium—>Low—>breathe
3 are high beam modes —>High—>Medium—>Low

short press on the power switches between low and high beam, but also forces the light again in highest mode

short press on the small or external button cycles between modes

>0.5s press on small or external button does full brightness high beam momentary

.

Conclusion
Solid build bike light, good functionality, but the manual has no information about the user interface.

Positive:

- mechanical good production and engineering
- solid aluminum body
- neutral white LEDs
- low and high beam
- a very useful illumination of the low beam with a sharp cut odd above the horizon
- transition between modes is faded, especially good with momentary high beam
- estimated runtime display and proper LVP and low battery warnings
- good capacity of the internal battery
- power bank functionality

Negative:
- no heat paste between body and MCPCB
- manual has no section for user interface
