EcoSlimLine T5 Lighting
T5 HO fluorescent lamps produce their maximum
luminous flux at 35°C, compared with 25°C for old
T8 fluorescent lamps with a tube diameter of 26 mm. Since
the temperatures in the luminaire are higher than the ambient
temperature of, say, 20 to 25°C, the efficiency is at
least 5% higher than for old T8 fluorescent lamps. The small
tube diameter of 16 mm also leads to an increase in the
efficiency of the luminaire. These lamps offer even more
luminous flux if they are operated within the luminaire
at their optimum ambient temperature. Excellent for energy
saving replacement of old HID lamps where high light output

Aquatic Plants: Actinic
Blue for Marine Plants and PURple for Tropical & Freshwater
Land Plants: Warning: All
fluorescent lights emit UV light, PURple emits proportionally
the most. When using any fluorescent lighting with early seedlings
or early cuttings they would be best be protected from copious
amounts of UV. This is easily remedied with a single sheet
of glass or perspex or plastic, between the fluorescent light
source and the plant tops, a Propagator top is ideal. (see
In many circumstances a combination of only
White and Red are traditionally used, White for all pre-flower
stages and red for all post flower stages. A favourite for
all pre-flower stages is 50% PURple and 50% Gold, a favourite
for all post flower stages is 30% PURple and 70% Red.
PURple is known to be favoured for growing
equatorial plants, such as Orchids and is proven to promote
the production of flavoids which can enhance the colour, odor
and and flavour of plants.
Why do plants need UV light?
UV increases the level of essential oils in mints & the
production of resin by trichomes of relatives, UV is used
for maximum yield and quality of these oils. UV induces color
development in flowers, essential for beautiful red veins
in green Kale or Chard.
Tasty Sunscreen? With added
UV light, an increased level of essential oils yields a more
powerful scent and flavour. The essential oils also aid in
the absorption of UV light , thus a sunscreen for plants.
Plants in the wild produce their own kind of “sunscreen,”
called flavonoids. Flavonoids screen out some of the more
dangerous UVB-type radiation.
