1. Engineering & Optical Overview
The T32-5080 Heavy-Duty Marine LED Navigation Bulb is engineered by MIDCARS for ocean-going commercial cargo vessels, fishing fleets, tugboats, offshore platforms, and naval patrol craft. Operating under relentless salt spray, continuous hull vibration, and severe maritime storms, traditional tungsten filament bulbs such as 40W, 60W, and 65W T38 navigation lamps frequently suffer from burned-out filaments and socket corrosion. The T32-5080 delivers an industrial solid-state drop-in replacement built to exceed demanding maritime longevity standards.
Constructed from CNC-machined marine aviation aluminum and fully potted with military-grade silicone resin to achieve certified IP68 submersible waterproof performance, the T32-5080 features a 360-degree cylindrical array of 50x to 80x high-efficiency straw-hat DIP LEDs. The 50-LED version draws 3.0W generating 300 lumens (replacing 25W-40W T25 incandescent bulbs), while the heavy 80-LED version draws 5.0W generating 500 lumens (replacing 60W-65W T38 bulbs). It is factory available across all international marine socket standards including P28S flanged prefocus, BA15d, BAY15d, E27, and B22, with discrete isolated driver configurations for 10-36VDC, 24-48VDC, and 100-240VAC marine power grids.
2. Multi-Base Mechanical Dimensions (1-Row 4-Grid)
Four standardized mechanical blueprint profiles ensure exact focal height alignment in marine fresnel navigation lanterns:

Engineered for full compliance with COLREGs maritime visibility sectors and certified navigation lantern housings:
4. Key Electrical & Mechanical Advantages
- Solid Aluminum Potted IP68 Waterproof: The internal cavity is fully vacuum-filled with thermal silicone resin, preventing saltwater intrusion and electrolytic failure even in direct spray.
- Direct 65W T38 Incandescent Retrofit: Matches the exact Light Center Length (LCL 45mm) of traditional T38 P28S bulbs, projecting light precisely through fresnel glass lenses.
- Vibration-Proof Solid-State Design: Eliminates delicate tungsten filaments that snap under high marine engine vibration and rough wave battering.
- Multi-Voltage Commercial Marine Grids: Discrete models engineered for 10-36VDC (yacht/workboat batteries), 24-48VDC (commercial tugs), and 100-240VAC (shipboard generator switchboards).
5. Primary Marine Navigation Applications
Commercial Vessel Masthead & Stern Lights
225° forward masthead lanterns and 135° stern navigation lights requiring certified 3-5 nautical mile visibility on commercial freighters and tugboats.
Port & Starboard Sidelights (Red & Green)
Dedicated monochromatic red (port 112.5°) and green (starboard 112.5°) or bi-color combination bow lanterns with sharp sectoral cutoffs.
All-Round 360° Anchor & Towing Lanterns
360° omnidirectional white anchor lanterns, dredging signals, and pilot vessel station lights operating continuously on 24V or 220V ship circuits.
Offshore Platforms & Channel Buoys
Solar-powered navigation markers, breakwater light towers, and offshore oil rig signal beacons demanding zero maintenance.
