18. Illumination system
18.1 Illumination for optimal plant growth
The chambers are equipped with day light fluorescent tubes. Optionally available are efficient FLUORA
®
growth illumination tubes for optimal plant growth or special Arabidopsis lamps. The fluorescent tubes are
built in light cassettes that can be freely positioned within wide areas. They homogeneously illuminate the
racks below them.
Daylight tubes
light color 865 (standard)
Fluora
®
growth lamps
light color 77 (optional)
Arabidopsis lamps
light color 841 (optional)
Figure 14: Spectral distribution of fluorescent tubes
Type of fluorescent tube: T8 fluorescent tube in form of a rod with a tube diameter of 26 mm / 1.02 in.
Length according to chamber size: 600 mm / 23.6 in (KBW 240, 400), or 900 mm / 35.4 in (KBW 720).
When operating the chamber with illumination: Restricted temperature range 20 °C / 68 °F to
60 °C / 140 °F
18.2 Adjustable light cassettes
Special reflector material in the cassettes ensures optimum light diffusion and efficient utilization of the
high light intensity. The lens of the headlight leads to a homogeneous intensity distribution even with a
short distance to the shelf. The fluorescent tubes are built in light cassettes that can be freely positioned
within wide areas. They homogeneously illuminate the racks below them.
