Uniform Lighting for Zebrafish Research

Uniform lighting across zebrafish systems — from left to right, top to bottom, and between racks — is not an aesthetic consideration. It’s a critical environmental control parameter that directly influences welfare, observation accuracy, and reproducibility.

ZebLED COB LED technology delivers

·       Smooth, continuous output – eliminating spotting seen on standard LED lighting, providing even illumination across rack systems.

·       Improved Welfare Through Environmental Stability - Fluctuations in light intensity and direction can induce stress responses, disrupt circadian rhythms, and alter behaviour. By maintaining uniform illuminance, zebrafish experience a stable visual environment — supporting natural behaviours, improving welfare, and aligning with Refinement principles.

·       Enhanced Visual Assessment for Health Monitoring - Consistent lighting enables technicians to perform accurate, repeatable visual inspections. The absence of shadow gradients or glare means early detection of disease indicators, morphological anomalies, or behavioural deviations becomes significantly easier and more reliable — reducing unnecessary interventions and contributing to Reduction in animal use.

·       Reduced Experimental Variability and Improved Replicability - Lighting uniformity removes a key environmental confounder. Standardised illumination between tanks and racks ensures comparable experimental conditions across replicates and facilities — strengthening reproducibility and supporting the Replacement of redundant experiments through reliable, validated outcomes.
