PEL-6 SECTOR LIGHTS<br />
• Up to 6 nautical miles range in<br />
daylight (coloured sectors, 3.5°<br />
subtense, 250 Watt TH lamp,<br />
favourable background).<br />
• Over 21 nautical miles range at night<br />
in coloured sectors, up to 25NM in<br />
white sector (3.5° subtense).<br />
• Automatic intensity reduction at<br />
night using lamp voltage reduction<br />
combined with insertion of neutral<br />
density filter.<br />
• Boundary definition and sector<br />
accuracy typically better than one<br />
minute of arc (for subtenses less<br />
than 20°).<br />
• Optional Oscillating Boundary<br />
provides up to four extra sectors and<br />
proportional indication of<br />
lateral changes.<br />
• Colour integrity – selection of correct<br />
colour filters ensures that sectors<br />
are recognised correctly in all types<br />
of weather.<br />
• Rugged construction and sealing –<br />
proven life exceeds 20 years in typical<br />
harsh marine environment.<br />
