X4Q Comet
Pairs well with
This is a solid torch that has great form and function. The optic in the X4Q has a nice balance of flood and throw. This little torch can put out a beam and still great for up close work. It’s a beautiful torch that feels great in the hand. This tint mix yields a nice and toasty beam. More like the darker parts of toasted sour dough bread. Tali Magnets could be stronger in the X4Q and X4 Stellar.
This is a solid torch that has great form and function. I love the metal button and RGB switch. For this configuration I chose a FFL351A 4000K / FFL351A 5000K tint mix and absolutely love it. The 4000K brings down the temperature of the 5000K for when you looking for something a little less bright than a full sun situation. The Timber Green finish and feel is also very nice. Tali Magnets could be stronger in the X4Q and X4 Stellar.
The X4Q Comet is FireFlyLite's best EDC model and rightfully so. It beats my similar sized Hank EDC in size and form factor. Yes it is larger than the D4v2 but the knurling and clip makes up for it. The X4Q easily slides in and out of tight pockets better than D4v2 due to the smoother yet grippy knurling. X4Q's clip + knurling combo doesn't wear-out your jeans fabric and makes the X4Q stay in place. The X4Q's driver and run time leave the 2 equivalent Hanks in the dinosaur age.
The D4v2 only comes with the obsolete boost driver while D4K comes with the old boost driver by default unless you send an addendum email to Hank after placing your order. That hassle is not required when purchasing any FFL torch.
The dessert tan color may be the least popular X4Q finish, but it provides better visibility when needed. Pictured is my X4Q along with my tan X4 and fossil grey V2S.
It's truly unbelievable that this lamp runs on 21700 battery. Is so small but great consistent package! Wonderful knurling and optics, especially one for throw! FFL LEDs are just amazing! I love 5000, 4000, 3700. All of them rock! Driver is stunning. Perfect replacement of H* lights...
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.

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.
