Obsta - Model HI STI-240V - Cold Neon Discharge Low Intensity Light - Brochure

The OBSTA HI STI is devoted to the marking of all kinds of obstacles such as buildings, airports, broadcast towers etc. The OBSTA HI STI is a one piece moulded assembly which includes a constant power converter and the proper discharge lamp (13 turns). The OBSTA HI STI P/N113110 has no requirement for a ground connection, which avoids any voltage return from the earth (for example due to lightning). However in intense electromagnetic fields (radiant poles, multi directional radio antennas), it is recommended to use the OBSTA HI STI APR P/N113113.
