Scheme Design
Inside a 7-meter-high aquaculture tank, there are 8 PVC pipes, with 12 light tubes inserted crisscrossing along each pipe. The light tubes are DC 48V, ensuring high safety and preventing electric shocks that could kill the seaweed inside.

Crucial Recommendations for Laver Cultivation
DC System is Preferred (24V or 48V recommended)
Reason:Laver farming involves long-term high humidity, salt spray, and frequent cleaning and spraying. Low-voltage DC systems (such as 24V) completely eliminate the risk of electric shock, providing the highest level of safety for farm workers.
Extra benefits:DC systems deliver cleaner, more stable current with no LED flicker, creating consistent lighting that supports steady photosynthesis in laver.
Use AC Tubes with Caution
Risks:AC tubes run directly on 220V mains power. While easy to install, even small damage to the casing or connectors in damp, corrosive salt-spray environments can cause electric leakage, creating serious safety hazards.
Suitable only for:Dry, non-spraying, well-ventilated auxiliary areas such as control rooms or warehouses.
FAQ
Q 1: Why can't standard white LED tubes be used for laver cultivation?
A: A: Standard white LEDs use a blue chip + yellow phosphor, so their spectrum is concentrated in blue and yellow-green light. But laver needs red light (620–660nm) for efficient photosynthesis, while it barely absorbs yellow-green wavelengths. Problems with standard white LEDs: Wasted energy – most light is in wavelengths laver doesn't use Slow growth – lack of red light limits pigment production Higher costs – need more power or tubes to achieve the same effect
Better choice: Use custom LED tubes with enhanced red light (e.g., red:blue ≈ 3:1) to match laver's light absorption peaks. This improves growth and saves energy.
Q2: My laver tanks are indoors, and the lights won't touch water directly. Do I still need a high waterproof rating?
A: A: Yes, you do. Laver farming environments typically have high humidity, condensation, salt spray (from seawater), and regular cleaning. Even if the tubes are not submerged, they still face these risks: Moisture intrusion: In high humidity, water vapor can seep into non‑sealed lights through gaps, corroding circuit boards or causing short circuits. Condensation dripping: Temperature differences cause dew to form on the tube surface, and water droplets can run into the connections. Cleaning operations: When washing walls and floors with water guns during regular tank cleaning, water mist will splash onto the lights.
