Features of NEC High Efficient Lamps

Higher Efficacy (lm/w)

  1. Tri-Phosphor Lamps provides Higher Efficacy (lm/W)
    Save Energy and Emission of Carbon Dioxide (CO2).
  2. Also provides Higher Color Rendering (CRI).
    Goods in shops looks attractive which increases Sale.

Comparison of Efficacy of 5000K Lamps

  1. Hf type’s efficacy (100lm/W) is higher than normal halo type lamp (80lm/W) which saves energy.
  2. Hf high out put type (45W) can reduce number of lamps and fixtures which saves money, save energy and carbon dioxide (CO2) with less materials and less wastes.

Horizontal Production Method

NEC’s Flush Clean Exhaust prevents the remainder of Impure Gas which decreases Lamp Performance

  1. Straight Lamps are produced on a Horizontal Production Line.
  2. One Way Method makes it possible to remove Impure Gas in glass tube more completely.

Long Life with Triple Coil

Triple coil used for our FHF32EX series.

  1. Lamp life depends on amount of emitter coated on coils.
  2. Triple coil has more emitter than double coil for longer life and better matching with electronic ballast.
