Features

Features

  • Enclosure is molded of SMC glass fibre reinforced polyester (GRP) with benefits of high strength, impact resistance and corrosion resistance;
  • Lamp shade is injected of polycarbonate with benefits f high light transmittance and impact resistance;
  • Light fitting adopts labyrinth seal structure with the performance of strong water resistance and dust resistance;
  • Famous brand fluorescent tube with long service life and high light efficiency;
  • Exclusive explosion proof ballast according to the tube type;
  • Adopt specified explosion proof lamp holder;
  • Light fitting are of mechanical interlock hold-down gear and automatic power failure. When open, it cuts off the lighting and emergency power supply. When close, lock the seal an automatic transmission.
  • With convenient locking structure, opened or closed the transparent cover can be quickly according to indication;
  • Lighting fixture with emergency unit will automatically shift to emergency lighting status when normal power is failed;
  • Special designed over charging and over discharging circuit inside emergency unit;
  • Steel pipe or cable wiring.
