Phytolux 2016 Seminar. “It’s not just about
light”
“Please Turn Off The
Lights.....”
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
A Saxil cabinet, older than I am, still in
use today.
Measured the effects on spectral output of:
• Chamber temperature
• Age of the fluorescent tubes
• Variability between manufacturers
• Dimming
Percentage changes differ substantially
between frequencies.
Fluorescent Spectrum Exponentially Affected When
Dimming
No two fluorescents are the same
Fluorescent Spectral Output Differs Between Manufacturer A and Manufacturer B
A small Walk-in Chamber
can contain as much as
10kW of thermal lighting.

Impact
Manipulation of the 14 frequencies has
enabled the “Low Green Fluorescent
Replication” providing the required
efficiencies and spectral output.
Fluorescent replication including the inefficient green spectrum
By Joining advanced BMS & DALI controls with LEDs we are
improving the research environment whilst saving costs and
carbon.
