20.2 Illumination for optimal plant growth – KBWF
The KBWF 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 24: 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 (KBWF 240), or 900 mm / 35.4 in (KBWF 720).
The waste heat of the fluorescent tubes leads to a modification of the temperature - humidity diagram:
When operating the chamber with illumination: Restricted temperature and humidity range
20 °C / 68 °F to 60 °C / 140 °F , at 20 °C not below 30 % r.H.
20.3 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.
