Traditional fluorescent tube lighting system is operated using T8 or T10 tube with electro magnetic ballast and starter. These king of lighting system is a low efficiency and high energy loss electrical products. The only way to achieve maximum saving of power consumption is to use high efficiency electronic ballast with T5 tube. By using Faeco's ETIT tube, saving of power consumption can be up 50%. Replacement is so simple as conventional tube, there are no need to re-wiring, modification to the existing lamp fixture. All the lamp fixture can be remained unchanged to avoid producing debris during retrofitting procedure. PODUCT CHARACTERISTIC: 1. Patent product (Tube in Tube Technology) 2. Saving of power consumption up to 50%, Power factor enhanced from\ 0.50 to 0.90 3. No rewiring and modification to the existing lamp fixtures, direct replacement 4. Replacement procedure is so simple as conventional tube 5. Life time up to 10000 hours 6. No sound and flickering when start up the lamp 7. By using T5 phosphor tube with less raw materials and smaller size and Higher colour rendering index of a light source 8. Lower operation temperature to reduce the loading of air conditioning system 9. Appropriate working temperature andno noisy during operation 10. Approved with CE and HK safety mark L00157A, comply to standard IEC61347 / IEC60598
