Osram 591582 HO 54/840 G5W

The FQ 54W 1149mm Linear Lumilux High Output T5 lamps produces up to 104 lumen per watt & 4000K Cool White Color. also offer Impressive economy and improved  environmental compatibility. With a tube diameter of only 16 mm, HO lamps are designed for ECG operation and, like all LUMILUX lamps from OSRAM, Are ideal in systems with motion sensors and/or daylight dimmers to reduced energy consumption to a minimum. With hot restart ECGs, T5 HO lamps achieve an average life of 24,000 hours and a service life of 18,000 hours.

• Up to 10% higher luminous efficacy of the LUMILUX T5 HO lamps compared with T8 lamps
  

• Up to 8% more light thanks to much less self-shading from the slimmer lamp
  

• Up to 10% higher luminaire efficiency because the Temp for optimum luminous flux has been raised to 35°C

• HO stands for High Output 
  
• 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
