The SEEMATZ marine searchlights are constructed of seawater proof aluminium and have extra hardened safety front panes.The reflectors are of aluminium.
Series HGS, HMI and ZH have thermostatically controlled heating.
These searchlights enjoy ease of servicing since the rear is removeable without using tools, by means of stainless steel quick release snaps.
As the cable glands as well are located at the rear, the complete sub- assembly consisting of mirror, socket, lamp and heating are removable for servicing or replacement of lamps
This may be of prime importance in cases of heavy weather conditions.
The stand-mounted types to be operated from the wheel house are totally watertight and very easy to install, simply by a single hole cut in the vessels ceiling.
Most models can be equiped easily with a signalling shutter.

SERIES AND TYPES
The SEEMATZ searchlights are grouped in series according to their type of light source and their diameter.

These series are:

Series HGS = Halogen Lamps
Series HBO= High Pressure Mercury Lamps
Series HMI = Metal Halide Vapour Lamps
Series XBO = Xenon Short-Arc Lamps
Series ZH = Tin Halide Lamps

All series are assembled with similar elements, in 4 sizes with diameters of 273,351,463 or 525 mm.

HGS Halogen Lamps
These lamps are the base of the extensive SEEMATZ range of advanced marine searchlights, and are suitable for many types of vessels and tasks.
Available from 24v to 220v. No compass interference from a distance of 0.5mm. Thermostatically controlled heating is standard.

HBO High Pressure Mercury Lamps
These are wellknown searchlights for sailing in polar areas. The extremely long range bluish - white light gets maximum reflection back from the ice.
The main advantage in this series is the small size combines with the greatest range. A warm up time of approx 1.5 minutes. No compass interference from a distance of 0.5mm. Thermostatically controlled heating is standard.

HMI Metal Halide Vapour Lamps
Suited as search and working light due to scattered angle, as used by trawlers and tugboats.
A warm up time of approx 1.5 minutes. No compass interference from a distance of 0.5mm, power supply from 2 m Thermostatically controlled heating is standard.

XBO Short Arc Lamps
These are multi purpose searchlights in the super class. They have illumination as daylight and enormous ranges and actually turn night into day.Very suitable for all types of vessels needing a maximum luminous efficacy.
Available from 75 w to 7000w. No warm up time. No compass interference from a distance of 0.5mm, power supply from 2 m. Thermostatically controlled heating is standard.

ZH Tin Halide Lamps
Suited as working light at a relatively close range e.g in fishing boats and trawlers.
A warm up time of approx 1.5 minutes. No compass interference from a distance of 0.5mm, power supply from 2 m. Thermostatically controlled heating is standard.
