High-Intensity Lighting for Approach, Runway Threshold and End

The 100W 6.6A P28s is used in elevated runway edge and approach lighting fixtures where higher candela output is required. Rated at 1,850 lumens with a C-2V filament, it delivers significantly more light than the 30W and 45W variants in the same P28s prefocus form factor.

This lamp operates on standard 6.6A constant current series circuits through isolation transformers. The P28s prefocus base ensures correct optical alignment in the fixture without manual adjustment.
