6116LL / 6121LL
High-Output Lamp for Runway and Approach Lighting
The 100W 6.6A PK30d is a halogen long-life lamp used in approach, threshold, runway edge, and PAPI fixtures that require higher intensity output. Delivering 2,700 lumens with a CBAR-6 filament at 2,000 hours rated life, it is a significant step up from the 45W and 65W PK30d variants.
Two variants are available, differing only in connector gender:
- 6116LL — Male connector
- 6121LL — Female connector
Both share identical optical and electrical specifications with 20 mm light centre length. The correct variant is determined by the mating connector in your fixture.
The PK30d cement-free prefocus base provides precise optical alignment. The lamp operates on standard 6.6A constant current series circuits through isolation transformers.
