3–5NM+ Marine Lanterns
Intensity/power settings on Sealite lanterns operate via DIP switches, located near the rotary switches
on the flasher unit. The intensity/power settings may be used to reduce the power consumption and
intensity of the lantern. Setting the lantern to 25% intensity will reduce the power consumption to 25%
of the normal 100% setting and the range by 20% - 40% depending on the maximum intensity. Refer
to Sealite power calculator to confirm reduced range. This setting may be used to adjust the current
draw of the light to local sunlight conditions.
The following diagrams indicate intensity/power settings:-
If the number of Full Sunlight hours is less than 2.5-3.0 hours, please consider reducing the intensity
(Power) or reducing the Duty Cycle.
Automatic Intensity Reduction for Fixed-On Character
• When the flash code is configured to 00 or ‘Steady On’, the maximum intensity is set to 50%. If a
higher intensity is previously set when the lamp is on, the intensity will automatically fall to the 50%
setting when flash code 00 is configured.
• The intensity settings available for lamps with a flash code set to 00 are 25% and 50%. The lamp
will flash an error condition if an intensity setting greater than 50% is selected with the IR Remote
Control.
• If the flash code is changed from 00 to another value, the maximum allowable intensity reverts back
to 100%.
