Level Lume builds ambient IoT hardware that turns real-time utility data into beautiful light. No app, no screen, no learning curve — just a glance.
Level Lume connects to your home's smart meter and water meter, then visualizes consumption through ambient LED light. Green means low usage. Yellow means moderate. Red means high. A water leak turns the light blue. No app to open, no numbers to read — homeowners just glance at a beautiful wall fixture.
Research from the 1970s showed that simply making energy visible cuts consumption by up to 30%. Level Lume applies that insight with modern hardware and design.
Black aluminium fixture. Slim, architectural, invisible against the wall. For the home that takes design seriously.
Natural oak frame with warm wood finish. Designed to blend into living rooms and hallways where presence matters.
Frosted acrylic halo with 360-degree ambient glow. A statement piece that belongs in the center of a home.
Level Lume is built by two co-founders — one based in Antwerp, one in the San Francisco Bay Area. Between them, they cover hardware design, firmware engineering, cloud infrastructure, web development, and product design.
The team has grown to include roles in engineering, sales, and operations. Every part of the product — from the PCB layout to the checkout page — is designed and built in-house.
The entire platform is designed for reliability and low operational cost. Hardware connects to cloud services with zero ongoing server management.
