Please rank your priorities for the operation of Controlled
Environments:
• Reproducibility of the environment
• Resilience of the facility to fault or failure
• Running cost and its potential impact on the scale of the trial
• Accuracy of the environment
• Carbon usage /environmental impact

Measured the effects on spectral output of:
• Chamber temperature
• Age of the fluorescent tubes
• Variability between manufacturers
• Dimming

Percentage changes differ substantially
between frequencies.

A small Walk-in Chamber
can contain as much as
10kW of thermal lighting.

enabled the “Low Green Fluorescent
Replication” providing the required
efficiencies and spectral output.
