Awarded the 2026 Best Product Design Award and Scientific Innovation Award, Billhol® represents a new generation of smart ambient lighting — compact in size, powerful in performance, and designed to transform any bedroom, lounge room, or kids’ room into a stunning 5D visual sanctuary.
🏠 No Perfect Wall? No Problem.
No perfect wall? No problem. Your room doesn’t need to be perfectly shaped, spotless, or completely organised. Billhol® adapts to your space, intelligently mapping your room’s layout to create a more realistic and immersive 5D projection experience.
Whether it shines across the ceiling, corners, furniture, or textured walls, Billhol® makes every galaxy and ocean scene feel naturally blended into your home — like the room was designed for it.
Just turn it on and let Topacmetransform your space into an immersive starry sky or deep-ocean escape.
Discover the future of night lighting — smart, immersive, and beautifully designed for modern homes.
Smart Network Sync. Endless Moving Scenes
The Billhol® HD Smart 5D Ambient Night Light features an intelligent network sync system that helps create a richer, more dynamic projection experience from the moment it’s switched on.
Rather than showing the same repeated patterns, Billhol® generates randomised moving visuals in real time — blending soft galaxy motion, flowing ocean waves, glowing nebula effects, and deep-sea movement into an ever-changing 5D atmosphere.
Every night feels different.
Every room becomes a new world.
From a peaceful starry sky to a calming underwater escape, the projection never feels static or ordinary. It moves, shifts, and evolves naturally, giving your bedroom, lounge room, or kids’ room a premium immersive atmosphere that feels truly alive.
🚗 Bring the Galaxy Into Your Car
Billhol® is not only perfect for bedrooms and lounge rooms — it can also create a calming starry atmosphere inside your car. The soft ambient light is gentle on the eyes and designed to feel relaxing, without being harsh or distracting.
Whether you’re parked, resting, camping, waiting, or enjoying a quiet night drive as a passenger, Billhol® fills your car interior with a beautiful galaxy-like glow, making you feel as if you’re sitting beneath a peaceful starry sky.
The light is soft, immersive, and atmospheric — adding comfort and wonder to every journey without distracting the driver.
