X4 Stellar
Pairs well with
Button has an inbetween pressure where it is not quite off or on, causing all kinds of misclick readings and wacky behaviour. You get told it is done by design. Would not recommend this light. Once they fix this and stop trying to say it's by design and that you need to click really hard. It would be good. But until then, save the trouble of dealing with android with a button that misread clicks
I got mine with the 1800K emitter to use as a cozy warm lantern. The Stellar doesn’t disappoint. The lantern attachment is top quality and a piece of excellent engineering. It securely attaches to the light allowing you to use the hanger without worrying about the light slipping from the lantern attachment.
The name says it all: The Stellar X4 is a stellar flashlight!
I ordered as red version, because i knew it would look fantastic. And boy it looks really awesome!
But its not only the outer appearance: All the newer Firefly flashlights come with a super efficient driver and they also have some very nice LEDs to choose from.
Of course, i wouldnt mind if there was even more LEDs to choose from, but i still give it a full 5 stars rating!
Von der Qualität einer der besten
Auch Lichtleistung und Reichweite super
The X4 Stellar is the first to support the lantern accessories, but I'm more excited to see the potential for those on lights like the Nov MU2S. Still, this like retains the black features that the Comet and Helios dropped, and for that I'm thankful. Similarly, the USB C charging is back! Supposedly this can be used as a power bank, but it's not the most convenient. A bit bulkier than the Comet but not too bad and still very pocketable. This thing packs a punch, just like the Comet.

User Interface: (Anduril V2)
This flashlight uses the open-sourced Anduril user interface. Anduril 2 is an open-sourced software and distributed under the terms of GPLv3. The source can be accessed here.
By default, this flashlight begins in Simple UI with 5 brightness levels. Enter the hidden Advanced UI to access additional features and more configuration options.
Details can be found in Anduril User Guide.
Charging
Stellar X4 features an intelligent 10W battery charger. For optimal charging, use a USB-C port that can source 5V 3A. Upon the start of charging, the side-switch illuminates red. When charging is complete, the red indicator turns off. A flashing red indicator indicates a charge fault (e.g. battery not inserted).
For battery safety, cells below 3V are pre-charged at 100mA before the full 10W charge starts, transitioning to constant voltage, and ending with trickle-charging. The charger includes a 10-hour safety timer to prevent extended charging.
While not recommended, the flashlight may be used while charging, but if operated at higher power levels than the charging rate, the battery will not be charged.
To enable 'OTG' power-bank mode, enter Momentary Mode (refer to the Anduril User Guide linked above). Note that not all phones or devices may charge using a USB-C to C cable. This may be mitigated by using some USB-C charging-only cables, or adapters that convert USB-C to USB-A, and then from A to mini / micro / or C. The maximum supported output is 5V at 1.2A. The flashlight may be operated at low to moderate levels in Momentary Mode when sourcing power, but at the expense of runtime.
Note - If a charge fault (flashing red LED on the side switch) occurs towards the end of charge, please remove the flashlight from the charger and contact Fireflies.
Battery Level Indicator
Anduril2 UI uses the front RGB auxiliary LEDs to indicate the current battery level upon turn-off. The colors correspond as follows:
This post-off display can be turned off or configured in Anduril.
Operation Notes
- Stellar X4 is a high-performance flashlight capable of up to 40W and generates a lot of heat. Please understand that this is not a toy and should be handled with safety.
- The default thermal regulated limit is set at 50C. This can be configured by the user to be higher or lower via the Anduril user interface.
- To prevent accidental activation of the flashlight, it is recommended to lock-out the flashlight (4 clicks from off to lock or unlock) before storage, or unscrew the body slightly as a mechanical lock-out.
- Stellar X4 has low-voltage protection which cuts off power at 2.8V. It is recommended to begin recharging the cell before this happens to increase battery longevity.
- For advanced users, the Lume X1 driver features UPDI flashing pads for advanced users to perform their own firmware updates or to flash custom firmware binaries.
