The mini/maxi compact rechargeable hand lamp has been developed especially for the travelling diver. The lamp provides excellent illumination despite it’s dimensions and weight.

 

Once again a micro processor controls and monitors the lamp with the following functions:

• The standard 20/50 watt HLX high power halogen Bulb is supplied with a controlled over voltage. The Bulb effectively has more than a 30% increase in illumination.
  
• A current limiter regulates the current in the first vital moments when the unit is switched on, thus protecting the delicate high performance Bulb.
  
• A 4 phase variable power setting allows the lamp to be adjusted to individual needs
  
• A magnetic field monitor prevents the unit from being activated by a foreign magnet.
  
• The discharge protection switches the lamp off and prevents the voltage in the cells falling below 0.9 volts.
  
• A low capacity warning informs the user with 3 blinks of the halogen Bulb, of the imminent end of the burn time. The lamp can then be switched over to a reduced power setting, thus extending the time before the lamp turns itself off.
  
• SOS Flashing according to the Morse alphabet, (3 x short, 3 x long, 3 x short), can be used as a distress signal.

The cell pack is a plug in unit and can be replaced within seconds with a second unit.
The spot reflector provides a soft transition from a bright center to a softly illuminated extremity. A special flood reflector for video use is available as an accessory.

 

Optional we offer Lithium-Manganese-Cells.

Since 2003 we took receipt of a newly developed
re-chargeable cell for test purposes, a lithium- manganese- cell. The electrode material is manganese sealed in a so called spinell rather than the traditional cobalt electrode.
The cells have proven themselves to be the "wonder cells" with the following properties:

• Excellent power properties and resilience
  
• Low self discharge, less than 3-8% per Month
  
• At temperatures as low as -15°C (+5°F), the cells retain 95% capacity
  
• A missing (defective) protection switch within the cell will reduce the capacity of the cell but will not produce an explosive reaction such as those previously mentioned in lithium ionen cells.
  
• Mechanical damage such as a blow or squeezing, or even a puncture of the wall of the cell such as with a nail will not produce a critical chemical reaction within the cell.
  
• For fully charged cells at high ambient temperatures, the aging process of these cells is considerably less than that in lithium ionen cells.
  
• Another feature that must be mentioned is that aged lithium manganese cells do not produce dangerous hydrogen gas and therefore make re-charging in a sealed housing much safer and in our opinion only now possible.
  The only disadvantage of the lithium manganese cells is that the energy density is approx 10% less than lithium ionen cells. Compared to the nickel metal hydride cells, the lithium manganese cells have 30% higher energy density

For the mini/maxi compact we offer interchangeable LED modules (mini compact 2x3Watt/maxi compact 3x3Watt, beam characteristic: spot).
The functions of the lamp, such as power control, activation of the SOS distress signal, and remaining burn time warning as well as total discharge warning will be fully sustained.
The existing reflector unit is replaced by the appropriate LED module. After removal of the halogen illuminant the electric contact is established by plugging in an adapter plug into the socket.
The electronic is protected against reverse polarity of the adapter plug.

What are the advantages of an LED-light?
An LED has an extremely long life span. It is considerably longer than that of a halogen bulb.
The LED is hard to break and very durable.

The cold white (bluish) light of an LED is not as strongly absorbed by the water as the warm white (reddish) light of a halogen bulb. Therefore, underwater an LED light has a greater range.
Due to the individual perception (only in dark environments!), cold white LED light seems to be stronger than warm white halogen light .

What are the disadvantages of an LED-light?
Fairly high costs of the LED and the necessary electronics.
Bad rendition of the red colour.

Conclusion:
We recommend the use of an LED-illuminant for night dives in freshwater, for dives in murky and cloudy water and for cave dives.
Despite a rather low power consumption of the LED modules, a sufficient brightness and a considerable longer burn time is achieved.
