LED Range Light E8552

We regret to inform you that this product is DISCONTINUED; please find our current products here

The Range Lantern E8552 utilize highly efficient LED technology to provide a narrow high intensity light beam guaranteeing  nighttime visibility range of up to 14 nautical miles. The light consists of an inner light unit box with a transparent polycarbonate front cover and  anodized  back cover, housed inside a powder painted outer metal enclosure with hot zink coated base plate and adjustment facility.  Optical and electronic devices: LEDs, custom lenses, and a controllable power supply unit - are protected from the environmental influence to IP67. The E8552 lights are currently available  in  one of the three colours. red, green, or white.

At  the  installation site, the light will be fixed to the host structure by the  base plate. Direction of the light beam around the  horizontal axis can be adjusted by rotation of the enclosure  with the light unit. Direction of the light beam in vertical plane   is adjusted  by deflection of the light unit within the outer enclosure.  For the precise adjustment of the light beam, an optional optical sight mounted to the upper backside of the light  can  be used.


  • Designed using Luxeon’s revolutionary, energy efficient and  compact new Lumiled STARTM light sources, combining the lifetime and reliability advantages of Light Emitting Diodes with optical lenses  designed at Cybernetica
  • High intensity (up to 18,000 cd) narrow light beam, field adjustable around vertical and horizontal axes
  • External control of flashing using a flasher of any available type
  • In order to extend the visibility area at short distances, we offer lantern versions with extended light beam formed by two or three additional wide angle light sources (see specification B). This is a  new feature, enabled by implementation  of LED technology

Note: STARTM  is a registered trade mark  of Lumileds Lighting, LLC
