This wireless LED lamp pack uses magnetic resonance coupling technology to power 10 LEDs without any wires or batteries. A transmitting coil creates a non-radiative magnetic field that wirelessly transfers energy through air, paper, or plastic to small receiver coils built into each LED bead — lighting them up as if by magic.
The technology operates at ultra-low power consumption and produces a magnetic field similar in intensity to the Earth's natural field, making it safe for people and other electronic devices.

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
