1. Designed with an optimal spectrum from a photobiological perspective (pineal gland impact) to support fish welfare and farming results in tank-based systems 2. A low dimming level (<1%) helps minimise stress when changing light levels, supporting soft start and soft ramp down strategies. 3. The 120-degree downward-facing beam is built to optimise light distribution above water and support stable environment. 4. Lightweight aluminium housing, anti-corrosion paint, and pole mounting make NIMBUS easier to install and better suited for harsh aquaculture conditions.
