Lei00 Silver is a silver edition limited to 200 units, born from our first collaboration with YANKO DESIGN (YD). Using neither electricity nor batteries, the heat of a single candle creates a breeze that carries scent through the room. 100 units are offered by Lei and 100 by YD, each accompanied by a certificate with its serial number.
Using no electricity at all, it creates a breeze from the heat of a candle alone.
Light flickers, shadows deepen, and between them, scent quietly drifts.
Founded in 2002 as a single design blog, YANKO DESIGN (YD) is now one of the world's largest product design media, visited by more than three million people every month.
Since first featuring it in 2022, YD has returned to Lei00 again and again. Founder Takashi Yamada says that of the countless products he has seen, Lei00 moved him the most. And Lei00 became YD's very first collaboration.
Only 200 units will be made — 100 offered by Lei and 100 by YD.
Why Mrwhosetheboss Gave This Battery-Free Aroma Diffuser a 9/10YANKO DESIGN, September 2026
Add 2–3 drops of your preferred essential oil to the oil holder.
Light the candle and set it in place.
The fan begins to turn, and the scent slowly spreads through the room.
“The flicker of a single candle, the breeze it stirs, the scent that breeze carries — and the richness of that time.” Lei is the world's most poetic aroma diffuser: instead of using a power outlet, it generates its own electricity from the heat of a candle. Like the fires people have gathered around since ancient times, it sits naturally between people wherever they come together, welcoming them and inviting them to slow down and enjoy the time and space unfolding before them. Made from materials that can be recycled, Lei turns the heat of a candle into electricity to create a gentle breeze, which carries the evaporating scent into the room. Its minimal form is designed first and foremost to move the heart, with cordless mobility and easy care. Both as an entirely new, self-contained home appliance that needs no outlet and as a product in its own right, Lei creates a new kind of value.
Compared with ordinary aroma diffusers, Lei's advantages are that it is cordless and easy to care for. Without a cord, it can be used almost anywhere — the living room or bedroom, the bathroom, even outdoors — and carried and set down wherever you like. Simply place aroma oil in the tray; refilling and cleaning are easy. It is also designed to let you enjoy the true character of a scent while using as little oil as possible. Many diffusers use so much heat that the intended scent is lost; Lei uses minimal heat to release the fragrance slowly, preserving its quality while keeping precious oil from running out quickly. The aluminum base gives it a low center of gravity to keep the candle from tipping over, and the glass cylinder makes it impossible to touch the flame, so it can be used safely.
Out of care for the environment, we use only three materials: aluminum, rare earths and glass. The packaging is recyclable too, so even after the product has served its purpose, everything can return as a resource. What Lei proposes is a set of values that will become standard in a near future beyond materialism. More than the simple facts of watching a flame or feeling scent and breeze, what matters is enjoying those phenomena and sensing the poetry hidden in time and space. Rather than chasing immediate function or convenience, Lei embodies a sensitivity to the space beyond the physical.
Belongs Anywhere
A quiet presence in glass and aluminum. From the living room, bedroom and study to the desk and even shops, it blends naturally into any setting. When the flame is lit, light and shadow appear, quietly settling the air of the room.
