Kailh BOX Night Firefly — Crisp Clicky Switch with 5-Pin | 50gf · IP56 · 80M Cycles

Kailh Night Firefly Clicky
Tired of boring switches that vanish in the dark? Sick of the cheap, scratchy rattle and metallic spring ping of classic blue switches?
Peripherals titan Kailh delivers an absolute showstopper that fuses visual magic with an immaculate auditory experience—the Kailh Night Firefly.
This switch pushes custom keyboard aesthetics to a whole new dimension. Unprecedented in the industry, it features a pink-purple high-clear PC housing infused with premium fluorescent powder, emitting an emerald firefly glow in the dark (no power required). Armed with Kailh's legendary Click-Bar mechanism, a golden 50gf actuation force, and a fast 1.8mm response time. Whether you're building the ultimate glow-in-the-dark desk setup or chasing an incredibly therapeutic, ASMR typing rhythm, the Night Firefly guarantees your board will be the absolute centerpiece, day or night.
Core Advantages: The Ultimate Fusion of Visuals & Sound
We know you love the distinct physical confirmation of a clicky switch, but you also desperately crave a unique setup that flexes your personality. The Night Firefly breaks the "Good Looks OR Good Sound" curse once and for all.
The Problem: Lights Out, Game Over
Standard clear switches entirely depend on your PCB's RGB. The second your PC turns off or you are in a dark room, your expensive custom keyboard loses all its visual magic and becomes incredibly boring.
The Problem: Cheap Plastic Rattle & Ping
Traditional clicky switches (like classic blues) use a plastic jacket that slams against the housing. It produces a scattered, shrill noise accompanied by maddening metallic spring ping.
The Problem: Boring Aesthetics & Degradation
Basic switches lack color coordination for clear keycap builds. Plus, cheap metal contacts oxidize rapidly, causing infuriating double-clicking or dead keys just months after building.
End Dim Aesthetics
Glow-in-the-Dark Magic
Sparing no expense, the high-clear Polycarbonate (PC) housing is innovatively infused with premium fluorescent powder, all while retaining a gorgeous pink-purple tint.
It automatically absorbs ambient daylight or room lighting. When the lights go out, it naturally emits a soft, stunning emerald glow without requiring any power or UV blacklights.
24/7 visual magic. By day, it's a crystal-clear pink jelly; by night, it turns your desk into a mesmerizing sea of fireflies. Brings an unmatched cyberpunk/mystical aesthetic to your barebones kit.
Kill Cheap Rattle
Crisp Click-Bar Acoustics
Driven by Kailh's highly acclaimed, patented Click-Bar mechanism. It generates a tactile snap on both the downstroke and the upstroke, paired with a snappy 1.8mm fast actuation.
Completely ditches the cheap, scratchy plastic rattle of classic blue switches. The sound is incredibly clean, sharp, and entirely devoid of messy metallic ping.
Every keystroke is an intensely therapeutic ASMR experience. The pure, retro mechanical feedback not only provides confident blind-typing accuracy but makes typing feel like playing an instrument.
Industrial Reliability
Pink-Purple PC & 80M Lifespan
Constructed with a dreamy semi-clear pink-purple PC housing that doubles as an incredible RGB softbox. Armed internally with anti-oxidation gold contacts and a rock-solid 5-pin base.
The 5-pin design drastically reduces horizontal stem wobble on hot-swap plates. The gold contacts completely eradicate oxidation-induced double-clicking or dead keys over time.
The perfect marriage of custom keeb aesthetics and industrial durability. Backed by a staggering 80 million keystroke lifespan, ensuring the crisp click and pristine glow last for years.

Real Reviews from the Keeb Community
"The glow-in-the-dark effect is absolutely insane!"
"I've never seen a switch designed like this. By day, they are a gorgeous pink-purple jelly. But the second I turn off my PC at night, my board literally glows a soft green like fireflies! It doesn't even need power. The cyberpunk aesthetic is unreal."
"The perfect match for my acrylic build. The sound is therapeutic."
"Threw these into my fully transparent acrylic hot-swap kit and it’s a match made in heaven. The Click-bar sound is incredibly clean without any of that messy, rattly garbage you get from classic blues. The 1.8mm actuation feels super snappy for gaming too."
"Not just a gimmick, the performance is hardcore."
"Bought them for the glow, but was blown away by the actual feel. The 50g force is the perfect sweet spot, and the 5-pin design sits rock solid on my board. Been daily driving them for months and the click is just as crisp as day one."
