X4Q Comet
Pairs well with
I got this with the 3700k emitter. I was blown away with how great it looks. Warm enough to feel pleasant on the eyes yet cool enough where it doesn’t feel like a novelty or people feel confused why a led isn’t the cold blue they are used to. The green color on this light looks amazing and the finish feels great in your hand.
I’ve been carrying it a ton since I got mine with the FFL351a 5000K LEDs. It’s my first FFL and it’s been performing great. It’s done well here at my day job. Pocket clip is fantastic, slides on nearly any fabric easily and the button feels great to actuate. Makes navigating Anduril easier. The neutral white beam looks fantastic and the battery is still at 3.7v. Charged it about 2 weeks ago. I’m not going out at night on walks but it gets used a good bit at my job to identify products. I’m really glad FFL supplies quality cells as an option. I liked this so much I ordered a Surge.
First firefly lite and I was blown away. The light feels incredible in hand. Nice finish and heft to it. The beam profile is great, perfect all around light
I have been using my 1800k/3700k mix as a bedside lamp and porch light all week and the battery is still at 3.5v. I am impressed with this driver. The flood optic is my favorite as well. Well done fireflylite! At this price point, this light cannot be beat.
Had to get two Comet’s, 5000K and 3700K. These lights feel solid and are highly pocketable lumen pumpers. Love the orange aux on these!

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.
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.
Note: The RGB will blink a few times after the post-off display on some X4Qs, it is hard to explain due to the firmware so far. It wont influence any functionalities , since it does not cause any confusion in use, we treat it as normal.
Operation Notes
- X4Q Comet 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.
- X4Q Comet uses the high-performance Lume X1 driver. For best performance, use high-drain unprotected flat-top 21700 cells only. Recommend cells include Molicel P42, P45, P50, or Samsung 40T, 50S, or Vapcell T50. Please handle cells with care.
- Batteries and external charger are not included.
- 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 a quarter turn as a mechanical lock-out.
- This flashlight 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.
- The Lume X1 driver (Rev B with AVR32DD20 MCU) features UPDI flashing pads for advanced users to perform their own firmware updates or to flash custom firmware binaries.
