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.
