Optimum light 

Decisive factors for the light intensity of a high-performance searchlight are the applied illuminant and the quality of the reflector. Optimal reflection peformance and even 20% more light intensity are obtained with the WISKA LiGHT parabolic mirror of glass. The 'A' searchlights are equipped with a reflector of high-gloss aluminium.

WISKA LIGHT searchlights are suitable for all ocean-going and inland-waterway vessels - typical examples being merchant vessels, along with Defence, Costal Watch, Search & Rescue, Police, Customs and Fire fighting. The following lighting elements are available to suit different applilcations and illumination ranges:

Halogen incandescent lamps are spotlights of temperature which emit up to 20% of the electric power absorbed ba a Wolfram light wire as light:

• constant light cololur

• Full luminous intensity after witching on, immediate restarting

• also suitable for onshore security

• average life time of lamps between 75 hrs and 400 hrs

• range up to 1,700 m

Halogen metal halide lamps stand out due to extraordinary light colour and optimal yield of light based on valuable metal additions in the discharge of gas:

• ideal for navigation in ice

• with separate power supply unit

• heating included

• constant light colour, hght portion of blue colour, nearly daylight spectrum

• full luminous intensity after 45 sec., immediate reignition without cooling period

• average life time of lamps up to 750 hrs.

• range up to 4,000 m

Xenon lamps are stuffed with pure xenon. The discharge bow burns under extreme pressure reaching the highest luminous density among all lamps. The xenon lamps have a very long working life.

• ideal for navigation in ice, long range

• with separate power supply unit

• heating included

• constant light colour, high portion of blue colour, nearly daylight spectrum

• full luminous intensity after switching on, immediate reignition without cooling period

• average life time of lamps up to 1,500 hrs

• range more than 8,000 m
