Model #721-1185-001

Bayonet Based Substitute for MS35478-305 and 307 Incandescent Lamps. This bayonet based LED product is qualified to MIL-STD-810 and approved for use on the C-130 platform. One 721-1185-001 LED lamp can replace a 305 and/or 307 (S-8) 28VDC, reducing the number of lamps in your inventory.

LED lighting provides greater initial luminance and far longer life. 305 and 307 incandescent lamps are used in a variety of aircraft dome, reading, and general purpose lighting and only provide a catalog life of 300 hours. The 721-1185-001 provides a minimum of 10,000 hours in service and uses less than half the power. The number of hours spent changing lamps will be greatly reduced.


  • Extremely durable
  • Greater initial luminance


  • Minimum of 10,000 hours in service
