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

One way to check this is to take several readings at slightly different distances. When accurately done, the source intensity will be independent of measuring distance. For practical measurements it is acceptable to work close to the limit of the photometer’s sensitivity. This could be more than 100 metres for some PEL-6 Sector Lights. Distances less than this will give false readings on the low side. An alternative method is to use a calibrated zero-range photometric facility, which simulates performance of the light at considerable distances (in far fi eld). DIMENSIONS PEL-6-3.5D 483 495 PEL-6-5D 483 495 PEL-6-7.5D 255 1929 Left-to-Right Sequence of Sectors Some PEL Sector Lights laterally invert the sector array out in front of the light. The left-to-right sequence of the sectors as they appear looking into the barrel will not necessarily be the way they are projected. Always check sector orientation from a distance. Focus at Infi nity PEL Sector Lights are normally focused at infi nity. This gives sharp sector boundaries at normal viewing distances. Within the fi rst few hundred metres the sector boundaries will appear blurred. 90 483 486 Clearance to remove Rear Can For servicing 495 495 PEL-6-15D 975 1288 483 260 1100 PEL-6 Mounting Layout 1893 1209 1398 495 714 PEL-6-10D 483 486 480 793 1100 218 230 495 144 PEL-6-20D 872 Non-Compliant M36 Lamps The original M36 lamp is ideally suited to the PEL-6 Sector Light. Some lamps now sold as M36 do not comply with the original specifi cation regarding lamp life, fi lament centre height, and pin diameter tolerance. These lamps must not be used in PEL Lights, as they run at higher temperatures, are prone to explode, and can crack lenses with excessive heat. For PEL-6 lights that are fl ashed, Vega recommends the use of Bailey M36 lamps, which have reinforced fi lament support wires. Other lamps may not give the rated service life. If in doubt, source replacement lamps from Vega. 45 350 65 483 155 230 240 nominal Scale 1:20 377 275 275 420 11
