Fireflylite’s New Versatile X4Q Comet Is an Enthusiast’s Must-Have

In an enthusiast market dominated by Hanklights with fully customizable platforms between Emisar and Noctigon models, it’s nice to see new challengers bringing some fresh new features to the table. The X4Q Comet is one of the latest such lights from Fireflylite, a compact, 4″ and 2.7oz (without the battery) light maximizing the 21700 battery form factor. But don’t let the size fool you; it’s packed with features like powerful LED emitter configurations (especially impressive ones Fireflylite make themselves), enthusiast-level drivers and interface in the Lume X1 and eminently powerful and customizable Andúril UI (naturally), all while offering a robust host build that still keeps the price somehow below 50 dollars.

The star of the show is the option to put in Fireflylite’s own FFL351A 4000K emitter into the X4Q, which not only gives it up to 2,600 lumens of output, but also comes with an incredibly desirable rosy white tint, one that hearkens back to the much celebrated, but discontinued, Nichia 219B sw45k emitter. The Lume X1 boost driver is also a standout, giving you enough brightness while staying efficient, and comes with constant-current power regulation as well as Ultra Dynamic Range (UDR) to be able to hit very low floors for moonlight or firefly modes.

In spite of its enthusiast internals, with its durable CNC-machined body, IPX8 water resistance, and 2-meter drop resistance, this light is still built to handle real-life adventures and serve you well as a main EDC. The X4Q doesn’t come with a USB port for charging like its sibling, the X4 Stellar, so keep that in mind if you don’t have a charger that fits the recommended 21700 batteries. Available in four colors: Timber Green, Navy Blue, Desert Tan, and Matte Black, the X4Q Comet is fun, functional, and has all the nerdery we could want from an EDC flashlight.
