Le Labo Solar energy Placed in a sunbeam, HELIA sets itself in motion. This magnetic solar system unites a glass-look sphere containing a small decorative element on a domed, metallic-finish base featuring a fine grid, with two rotating rings that slowly orbit it. No batteries, no cables: an integrated solar cell captures light and maintains rotation as long as the lighting is sufficient. The result evokes a stylized planetary model, a little miniature celestial mechanism whose movement changes with the hour and the clarity of the day. Its sphere appears suspended at the heart of the rings, and the eye constantly returns to this discreet ballet. HELIA finds its place on a desk, a shelf, a windowsill, or a car dashboard. As a secondary function, a small compartment under the lid holds scented tablets for a subtle olfactory touch. Four colors are offered: black, red, gold, and silver.

How does light make the rings turn?
Magnetic solar systems of this type generally rely on a simple and ingenious principle. A photovoltaic cell converts the received light into a weak electric current. This current powers a small circuit that sends an impulse to a copper wire coil at regular intervals. When current passes through it, the coil briefly becomes an electromagnet.
A magnet is fixed onto the moving part. Each time it passes over the coil, it receives a small magnetic push that boosts its momentum; the inertia of the rings does the rest between impulses. This is in no way a perpetual motion machine: the rotation lasts as long as there is sufficient light, slows down when it fades, and stops in the dark. That is why the object thrives near a window or in the sun, much more so than in the glow of a dim lamp. The manufacturer does not detail the exact internal mechanism of this model: this description corresponds to the general principle of the family of objects to which it belongs.
Why you will love it
Celestial mechanics in the palm of your hand
Ever since the first mechanical orreries in cabinets of curiosities, humanity has loved holding the universe in miniature: spinning spheres, orbits followed by the finger, an order one can intuit. HELIA takes up this tradition with thoroughly contemporary economy: a sphere, two rings, and daylight as the only motor.
The design plays on contrasts. The domed base and its grid have an almost technical look, the glass-look sphere catches and reflects light, while the rings draw trajectories that intersect and disentangle as they rotate. Depending on the sun's angle, the show changes: vibrant in the mid-afternoon, slower as the day fades.
It is this connection to light that gives it its charm. Like a sundial, HELIA lives to the rhythm of the day and serves as a quiet reminder that all the energy animating it comes from a star 150 million kilometers away.

Good to know: HELIA runs on light, and its speed depends directly on it. In the sun or near a bright window, the rings spin briskly; under dim artificial lighting, they may turn slowly or even remain still. In darkness, the movement stops: this is normal, and it resumes as soon as light returns.
Tip: to enjoy the show as long as possible, place HELIA on an east or west-facing windowsill, which receives beautiful light in the morning or late afternoon. Occasionally wipe the solar cell with a soft, dry cloth: a thin layer of dust is enough to reduce the energy captured.

Precautions: the sphere has a glass appearance: handle the object with care and avoid impacts and falls. The compartment and any scented tablets contain small parts: this is a decorative object that is not suitable for children under 3 years old; keep out of their reach. On a car dashboard, place it on a flat surface without obstructing the driver's visibility or the airbag deployment zone, and do not handle it while driving. The mechanism of this type of object generally relies on a small magnet: for caution, pacemaker users should avoid keeping it against their body. Do not leave scented tablets in contact with delicate surfaces.
A luminous gift for curious minds
HELIA will appeal to an astronomy enthusiast, a lover of beautiful desk objects, a colleague who works by a window, or a driver who loves customizing their interior. For a birthday, Christmas, Father's Day, a farewell, or an original corporate gift, it has the merit of being at once decorative, intriguing, and environmentally friendly.

Frequently asked questions
How does a magnetic solar system work?
Objects of this type generally combine a solar cell, a small circuit, a coil, and a magnet. The cell transforms light into a weak current; the circuit sends it in pulses to the coil, which briefly becomes an electromagnet. The magnet fixed on the moving part is then pushed away with each pass, which restarts the rotation, and the inertia of the rings maintains the movement between pulses. The manufacturer does not detail the exact internal mechanism of HELIA: this is the general principle of this family of objects, which explains why rotation depends directly on the light received.
Do the rings rotate permanently?
No, and that is the whole point of the object: HELIA lives to the rhythm of the light. The rings spin as long as lighting is sufficient, more vigorously in the sun or near a bright window. When the light dims, rotation slows down; in darkness, it stops completely, then resumes as soon as light returns. It is therefore not a perpetual motion machine, which is physically impossible, but a movement maintained by solar energy. No battery or accumulator is mentioned by the supplier: the object does not store energy for the night. This dependence on the day is part of its charm and its educational value.
Does it work under artificial light?
A lamp may suffice to maintain the movement if it is powerful and close to the solar cell, but the results are significantly less effective than in natural light. Under dim ambient lighting, the rings may spin very slowly or even remain still. For consistent operation, we recommend a location that receives daylight: a windowsill, a desk facing a bay window, or a dashboard. If you wish to install it in a dark room, consider it primarily as a decorative object that will come back to life as soon as it finds a sufficient light source.
Does the sphere really float?
The glass-look sphere is placed at the heart of the two rings, and their rotation gives the impression that it is suspended in the center of a small planetary system. However, the supplier does not confirm levitation per se: we prefer not to promise it. What matters here is the visual effect of the rings tracing their orbits around the sphere and its interior decor, and the solar and magnetic principle that drives them. If you are looking for a true magnetic levitation object, Le Labo offers floating globes powered by mains electricity, presented in our comparison table.
Are the scented tablets included?
The supplier does not confirm the presence of scented tablets in the package: consider them not included, unless otherwise stated. The scent is, in any case, a secondary function: HELIA is primarily a decorative and scientific object. If you wish to use it as a subtle diffuser, simply unscrew the compartment lid, place a few small scented beads or tablets inside, then screw it back on. Choose dry refills, without liquid, to preserve the mechanism and the finish. You can also leave the compartment empty and simply enjoy the movement of the rings.
Can it be placed on a car dashboard?
Yes, and that is actually how the manufacturer showcases it: the windshield provides it with abundant light. Place it on a flat and stable area where it will never obstruct the driver's visibility and remains clear of the airbag deployment zone. No mounting system is mentioned by the manufacturer: verify that it is not at risk of sliding during turns, and do not manipulate it while driving. In summer, a vehicle interior can become very hot; if you leave it there, monitor the condition of the object and any tablets. At home, a windowsill offers a more serene environment.
What are its dimensions and which color should I choose?
According to the supplier's specifications, HELIA measures approximately 6 cm in diameter by 6 cm in height: a small, round object that can be placed on a desk, shelf, or dashboard without taking up space. Its weight is not specified. In terms of finishes, four colors are available. Silver and Gold bring brightness and are suitable for light-colored interiors; Black, enhanced by a red border at the base, offers a sober, graphic look; Red provides a bold touch that stands out at first glance.
