Jellyfish lanterns are the signature element of marine-themed light displays and always become viral social media hotspots.
Design features
Translucent silk fabric forms the jellyfish dome, with long, flowing tentacles. Built-in programmable RGB LED lights create slow color gradients, simulating soft bioluminescence in deep seawater.
Flexible installation methods
Size options
Available in small hanging jellyfish (1–2m) and giant standalone jellyfish (3–8m high). Cluster multiple jellyfish in mixed heights to create layered, floating underwater visual effects.
Many clients choose to line entrance paths with groups of jellyfish lanterns, letting visitors walk through a glowing jellyfish forest. This setup generates plenty of photos and short videos shared on Instagram, TikTok and Facebook, bringing free organic promotion for your event.
If you need a striking landmark installation, custom octopus lanterns are an excellent choice.
Classic design options
Octopus arch gateway: Octopus tentacles wrap around the entrance arch, forming an immersive entry tunnel for the whole ocean zone.
Free-standing octopus sculpture: Giant octopus crawling along the ground or reef lantern sets, creating a mysterious deep-sea atmosphere.
Customizable details
We can adjust tentacle poses, add hand-painted texture patterns, and install dynamic lighting effects. For premium projects, optional slow movement mechanics can make tentacles sway gently.
Octopus lanterns work perfectly as main photo check-in spots, especially for summer events, seaside carnivals and aquarium seasonal exhibitions.

Single jellyfish or octopus lanterns look beautiful, but a full immersive underwater scene delivers far better visitor experience. We recommend matching these supporting elements:
Layout suggestion:
Place a large octopus arch as the main entrance. Arrange clusters of jellyfish along the main walking trail. Fill gaps with coral and fish lanterns to create depth, turning ordinary walkways into a continuous underwater adventure.
Ocean-themed lantern scenes with jellyfish and octopus elements continue dominating global light festivals. These luminous marine sculptures turn ordinary venues into magical underwater worlds, effectively increasing stay time and social sharing for your attraction.
Whether you need a single landmark octopus arch, rows of floating jellyfish, or a full large-scale underwater lantern exhibition, our factory provides one-stop custom design, production and technical guidance.
