Company history

OBSTA, a subsidiary of CITEL group (www.citel.fr) is part of an industrial group that engineers, manufactures and sells obstruction lights for transmission lines, telecom, broadcasting towers and all kind of obstacle to air navigation. more than 30 years. Or obstruction lights are manufactured by us based on ICAO annex 14 chapter 6 (International Civil Aviation Organization) recommendations and the FAA (Federal Aviation Administration).

OBSTA has manufacturing facilities in France and has sales office located in France, Germany, USA, and China through Citel.

A long history

Before joining Citel in the years 90, Obsta was part of the company Claude that was manufacturing all kind of lamps. This company was created by Georges Claude (September 24th 1870 – May 23th 1960) a French physicist and chemist :

1902 : Extraction of rare gas from the air (neon, argon, xenon..) and creation of the company Air liquide
1910 : Invention of the first modern patented discharge lamp tube and creation of Claude company manufacturing all kind of discharge and incandescence lights
1960 : Invention of the first balisors for transmission lines
1992 : Bought by Citel manufacturing gas tube and surge protection
2003 : New led NAVILITE obstruction lights red fixed
2008 : New obstaflash led series flashing type medium and high intensity

Specialist in obstruction lighting

Over the years, tree large product families have been developed in the respect of the most severe standards, requested by our customers, neon xenon and led type. OBSTA lights are designed in the respect of the latest international standards that are ICAO and FAA. They constitute a complete range low intensity or L-810, medium intensity or L-865/L-864 and also high intensity, ideal for broadcasting towers, telecom mast, transmission lines, stacks and wind turbines.

- Cold neon discharge lights,
- pure cold neon discharge 5 and 13 turns OBSTA® HI STI & STI,
- 33 & 49 turns BALISOR® (conductor warning lights) red fixed obstruction lights.

Led NAVILITE® red fixed obstruction lights (low intensity and L-810) since 2003 The NAVILITE series is dedicated to night only obstruction lights especially for telecom mast, buildings close to airports and all kind of obstacle below 45 meters high. Completely molded with 64 leds divided in 16 independent led circuits, they are ideal for all kind of obstacle
