Features
- DuaLens Optical Design for Road Biking Mode, providing broad closed range flood light with
anti-glare low beam for commuting, no dazzle and glare for oncoming riders and pedestrians. - HiLo Beam System for Mountain Biking and Emergency Modes, providing illuminating light similar to
automotive headlight with far reaching high beam and low beam. - LED real-time display to show remaining runtime in each brightness level.
- Micro USB charging port, compatible with most phone chargers.
- USB output port to charge other USB-powered digital devices.
- Intelligent thermal management circuit to prevent overheat of LEDs.
- Intelligent Memory circuit remembers the last used brightness level and mode when turned on again.
- Quick release design for easily slide in and out.
- Compatible with handlebar from 22.2mm to 31.8mm diameter.
The parcel arrived after 16 days shipping with to Germany which is good from China.

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
Beam shots
distance to wall 10m
my last bike light Klarus XT11GT with XPL HI V3-3C
narrow hotspot and useable spill
Ravemen PR1200 low beam
Ravemen PR1200 high beam
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
