X4Q Comet
Pairs well with
Lovely form factor. The light has a slimmer profile compared to the X4 Stellar due to removing the usb charging port. The aux on this particular model seems to be much more vibrant and saturated, especially certain colors like pink. All in all a great addition to my growing collection of fireflies lights!
This might just be the perfect quad! I am more than satisfied with the finish, feel, and focus (of the beam).
The blue anodization of the Comet is quite similar to the gray/blue finish of Hanklights: only slightly darker. It's a deep, steely hue that exudes elegance in harmony with the overall design language.
The Comet's clip design is sleek and functional.
My favorite design element of the Comet is the bezel. Its glossy finish along with the the clear optic and aux lights is just beautiful. And the minimal crenulation adds a needed edginess to the otherwise formal design.
In my opinion the white aux set to low is very classy. (I've set my black X4Q Comet to high green aux, and it also looks great with pink.)
The button's actuation is flawless, and feels amazing with the deep travel and clear click. I don't know if the nub is stainless steel (it almost feels like plastic) but it doesn't matter. The synchronized RGB button is a nice touch.
And the beam... is perfect. I specially requested a 3700K/5000K mix for a modest $5 upcharge - it's like 5700K 519A dedomed but maybe somehow even better: silky smooth even with the throwy optic, and just a touch rosy. It's still a great color temperature for general use and neutral enough tint for serious jobs, but also very pleasing to the eye.
Overall, this light is meant to be carried, not just collected - and I think it does outstanding in both of those roles. So far... impressed.
I have to remove the battery a few times a week to get the flashlight to come on but my other firefly lights have the same problem.
The knurling on the handle is attractive and functional, it doesn't chew up my jeans but still gives me a confident grip. The switch is very clicky and illuminated with an RGB LED switch that has nice color options. I ordered mine with a 4000K/1800K mix and the tint is just gorgeous, definitely worth the small amount extra.
Great addition to the X4 series, while the onboard charging is slightly missed the more compact and edc friendly design makes up for it. Ordered the 4k ffl led version, it is noticeably cooler cct than the E07 cannon version i have but it works well anyway. Great to pair with Pharos or X1 elite which have charging onboard. Addition of rgb button is nice as well.

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.
