Osram 21W Skywhite fluorescent 849mm lamps with light color 880 (color temperature 8000K with good color rendering) are characterized by their impressive quality of light. They emit a large proportion of “blue” light in the wavelength range from 410 to 460 nm and therefore come very close to the character of natural daylight. This in turn means that SKYWHITE improves contrast and reduces visual fatigue – and that is known to boost mental and physical performance. The high luminous flux and high efficiency (up to 85 lm/W) of Osram Skywhite are equally impressive & Are the ideal choice wherever high levels of concentration, attentiveness and well-being are needed in conjunction with special visual requirements:

• Corporate and public buildings – in stairwells and corridors, single and open-plan offi ces, conference rooms and hospitality rooms
  

• Modern industrial plants and pro- duction complexes – day and night, including shift work

•  
• HE stands for High Efficiency.
  
• This system offers excellent properties such as good luminous flux behaviour,
• Impressive economy and improved environmental compatibility.
  
• With a tube diameter of only 16 mm
  
• These lamps offer an extremely high luminous efficacy of up to 104 lm/W (at 35 °C).  
• They are designed for ECG operation and are up to 20 % more efficient than LUMILUX T8 lamps.
• With hot restart ECGs,
  
• T5 lamps achieve an average life of 20,000 hours and a service life of 16,000 hours.
• They also enable extremely slim and compact luminaires to be created
• Suitable for ECG operation only/Lamp designed for internal luminaire
•  temperatures of 30…40 °C; optimum luminous flux achieved at 35 °C
