Plasma Ring Light – Electrode-Free Xenon, Krypton & Neon Plasma Sphere (90mm / 130mm)

A real ring of glowing plasma, floating inside a glass sphere on your desk. This is not your childhood plasma ball: instead of random lightning arcs, you get a steady, adjustable glow that you can watch for hours. Choose your gas, sphere size and base below.

Choose Your Gas

Each noble gas glows in its own color and forms its own shape.

Xenon

Purple Ring

A crisp blue-violet ring of plasma, floating in the center of the sphere. The classic plasma toroid look.

Krypton

Pink Beads

Soft pink plasma beads that glow and drift inside the sphere. A gentler, more organic effect.

Neon

Red Glow

A warm red plasma glow, the same color that made neon signs famous.

Choose Your Base

The glass sphere and plasma effect are the same. The difference is how the base is made.

Why You'll Love It

• Real plasma, not a plasma ball: A classic plasma ball shows random arcs. This lamp forms a stable plasma shape in the center of the sphere. The xenon ring is the same donut shape (toroid) studied in tokamak fusion research, at desktop scale.
• Electrode-free: An induction coil around the sphere excites the gas from outside the glass. Nothing inside touches the plasma, so there are no electrodes to wear out.
• Adjustable with one knob: Turn the knob to start the plasma, then adjust its brightness and how thick the glowing ring appears, from a fine line to a bold band.
• Interactive: Bring your finger to the glass and watch the plasma react.
• Bright enough for a lit room: The glow stays clearly visible with the lights on, and looks even more striking in the dark.
• Made for your desk: A conversation piece for engineers, makers and science fans, and a memorable gift.

How to Use

1. Place the lamp on a flat, dry surface. Make sure the glass sphere is seated in the coil before powering on. Never run the lamp without the sphere.
2. Connect the power adapter and plug it in.
3. Slowly turn the knob until the indicator light comes on and the plasma forms.
4. Once the plasma appears, turn the knob back slightly. This normal setting is ideal for long viewing.
5. If the plasma does not form, touch the glass sphere and restart the lamp.

Safety & Care

• Glass sphere: Safe to touch. It warms up during use, so avoid keeping your hand on it for long periods.
• Enclosed base: The whole base is safe to touch.
• Open-Frame base: Touch only the glass sphere and PVC parts. Never touch the metal parts, coil or circuit boards while the lamp is on, as this can cause electric shock or burns.
• Turn the lamp off and unplug it before moving it.
• Handle the sphere with care, especially the sealed glass tip on top.
• Keep the lamp in a dry, well-ventilated spot. It is not waterproof.
• People with pacemakers or other implanted medical devices should keep a distance while the lamp is on.
• Keep away from children and pets. Recommended for ages 16+.
• Use only the original power adapter. Do not disassemble: the lamp contains high-voltage circuitry and a sealed low-pressure glass sphere.

Specifications

Size Guide

Note: The 130mm sphere is wider than the base, so allow about 135mm (5.3") of desk width.
