The full spectrum light of lamps of the NARVA BIO vital series contains beside the full range of the visible part of the spectrum also some components of the UVA and UVB ranges of the spectrum. It is almost completely equivalent by effect to natural sunlight with its well-known feel-good advantages. In addition, the light has an excellent colour rendering property (Ra 1A) also. These lamps are used wherever there is required to compensate the lack of natural sunlight.
NARVA BIO vital has:
-the UV component's revitalising effect
-a balanced spectrum which gives practically the same effect like natural sunlight
-very good colour colour reproduction (Ra > 90) and excellent contrast sensitivity
-80% energy-saving compared to conventional bulbs
Plant breeding and nurseries
The correct light is one of the main factors governing successful plant growth. The blue elements of the spectrum are particularly important in plant breeding. NARVA BIO vital lamps have a colour temperature of 5,800 K and fulfil this requirement perfectly.
In intensive animal farming, be it dairy cattle sheds, piggeries, or poultry sheds, the animals usually spend their whole lives under artificial light. The NARVA BIO vital range of lamps can compensate to a great extent for the deficiency in natural sunlight, and so improve the conditions in which the animals are kept.
Auditoriums and lecture theatres
High quality lighting is an important factor in facilitating focussed, fatigue-free learning. The light from the lamps in the NARVA BIO vital range is similar to sunlight, and ensures high levels of concentration even over lengthy periods of time.
Nurseries and schools
The UV component has an important effect on bone formation (vitamin D production) and helps to strengthen the immune system. Furthermore, the NARVA BIO vital range of lamps greatly facilitates colour vision.
