Performance and reliability
•
GE’s advanced sodium resistant ceramic helps eliminate
early failures to give a rated service life of 10,000 to 12,000
hours for Lucalox™ PSL products.
•
In order to achieve maximum performance, GE recommends
lamp replacement when the Rated Service Life is reached.
•
The lamps use extra rugged monolithic arc tubes equipped
with GE Reliable Starting Technology which provides
continuous high performance.
High xenon-fill gas
•
Extra light and PAR
(Photosynthetically Active Radiation) output.
•
More resistance to mains voltage fluctuations.
Zirconium gettering system
•
Improves PAR maintenance that drives constant and
uniform plant growth.
•
The diameter of the frame wire in the lamp has been
minimised to reduce shading in the installation without
affecting the robustness of the lamp.
•
Monolithic arc tube construction for durability and
lumen maintenance.
PSL technology
Photosynthetically Active Radiation
to extend daylight
The effect of optical radiation on plants has been studied
extensively. Generally, photons emitted in the spectral region
of 400 - 700nm are particularly effective. Therefore the simple
measurement of the quantity of light (Lux) is not sufficient for
the horticultural market . Photosynthetically Active Radiation
(PAR) and Photosynthetic Photon Flux (PPF) are more useful
measurements.
PPF is defined as flux of the photons emitted in the
400 - 700nm wavelength range by the light source. It is
expressed in micromoles/second (µmol/s), where 1 micromole
means 6x10
17
photons.
The Lucalox™ PSL range from GE has optimised spectra
for greenhouse use, with an enhanced red portion of the
light output .
•
Plants can be used over a longer period
•
In winter, fruit can be produced with taste to match
summer fruit
•
Production can start earlier
•
Year-round cultivation is possible

Relative sensitivity
Wavelength [nm]
Plants have different sensitivity to different
wavelengths.
Spectral range
Plants respond to light of varying colour. In
general, red light causes plants to become tall
and “leggy” while blue light , when used alone,
can cause low, stocky growth. A proper balance
of red and blue energy produces plants that
have normal growth and shape.
