— The Problem

Every year, the world
throws away 15 billion bulbs.

Modern LEDs are sold with a promise of 25,000 hours — and engineered to fail in 8,000. A whole driver board, heat sink, and aluminum housing get tossed because one filament burned out. We thought that was insane. So we re-designed the bulb from scratch.

Smoothly dimmable.
From candle-low 1% to full output. No flicker, no buzz, on any standard TRIAC dimmer.
— How it works

Twist. Swap. Forever.

The housing is built once — from solid brass and borosilicate. The filament is the only consumable. Replacing it takes 12 seconds and costs €4.

01

Power off. Cool down.

When you notice the filament dimming, simply flip the switch and let the bulb rest for two minutes.

02

Twist the glass cap.

A quarter-turn unlocks the borosilicate top. No tools. No mess. The cap is keyed so it cannot be over-tightened.

03

Lift the spent filament.

Magnetic contacts release the old filament cartridge. Drop it in any recycling bin — it's 100% glass and tungsten.

04

Drop in a fresh one.

Refill cartridges ship in a small reusable tin. €4 each. Twelve flavors of warmth — from candle 1800K to studio 4000K.

05

Glow on, forever.

100,000 hours later, do it again. The housing is engineered for at least four refills — about a century of daily use.

— Why it lasts forever

Six reasons it
outlives everything else.

100,000h rated life

Even at 8 hours every single day, that's over 34 years per filament. With four refills: a century.

8W = 75W incandescent

Drops €30 per bulb-year off your electricity bill versus a vintage Edison. Without losing the look.

CRI 97 warm light

Renders 97% of natural sunlight's color spectrum. Most LEDs hit 80. The difference is unmistakable on skin and wood.

Flicker-free dimming

1% to 100% on any TRIAC dimmer. No buzz, no strobe, no eye strain. Tested at 50Hz and 60Hz.

94% less e-waste

Only the filament gets replaced. The brass housing, driver, and glass stay in service — never landfilled.

Lifetime warranty

Housing fails — we replace it. The brand is the bet. Free shipping on all warranty claims, forever.

"I installed mine in a velvet pendant over the dining table. Every guest stops mid-sentence to look up. It's not a bulb, it's a piece of jewelry that happens to make light."

"The filament swap took me eleven seconds. My eight-year-old did the second one without me. This is what every appliance should feel like."

"After three years in our café, every other LED has died. The two EverBulb prototypes are still on, still warm, still gorgeous. I'm replacing every fixture we have."

"I bought one as a gift and ended up keeping it. Re-ordered six. It feels weirdly emotional to own a bulb that's going to outlive me."

Three years of R&D in Stockholm. Two patents on the magnetic filament socket. A custom driver chip that runs cool enough to touch — which is why the brass housing never warps.

— Questions, answered

Frequently asked.

The filament cartridge — the glowing part — pops out of the brass housing with a quarter-turn. The cartridge is the only consumable. The housing, driver, and outer glass stay forever. Refills cost €4 each and ship in tins of six.

Three reasons. We underdrive each LED at 35% of its rated current. The brass housing acts as a passive heat sink — no electrolytic capacitors. And the filament cartridge is sealed in xenon, not air, so the tungsten doesn't oxidize. Result: tested 14,200 hours so far with no measurable degradation.

We replace it. Lifetime warranty on the housing — that's the bet we're making as a brand. You just email a photo. We ship a new one. Free.

Yes — tested with Lutron Caséta, Philips Hue Wall Switch Module, Shelly Dimmer 2, and 14 other major TRIAC dimmers. We don't do Bluetooth or WiFi — we believe a bulb's job is to make light, not push notifications.

Backers ship in June 2026 in batched waves — earliest pledges go first. Refill subscribers start receiving filaments quarterly from October 2026.

Absolutely. We ship worldwide. North America, EU, UK, Australia, and Japan are flat-rate. Everywhere else is calculated at checkout. All taxes & duties handled by us — no surprises at customs.
