New Fambach test hall: every light photometrically tested before it ships

A 1,200 m² hall with three goniophotometer stations, a climatic chamber and a series-circuit endurance line. Here is what happens to a light before it reaches an airfield.

Every fitting passes the same photometric test as the type sample that was certified.

Certification proves that one sample meets the standard. Airports need every light to meet it. That is why we built a hall where each unit is measured before it leaves Fambach, not only the type sample.

Three stations, one report

Every light passes three stations in sequence. The results are stored against its serial number and travel with the delivery.

  • Photometry. A goniophotometer measures the beam in 0.5° steps and compares it with the ICAO Annex 14 isocandela diagram.
  • Climate. Twelve hours between −40 °C and +70 °C at 95% humidity, then a seal check under pressure.
  • Endurance. 72 hours on a 6.6 A series circuit, stepping through all five brightness levels.
“An airport should never be the place where a light is tested for the first time.”Dr. Lena Hartmann, Head of Quality

Open to customers

Customers are welcome to witness factory acceptance tests. A viewing gallery overlooks all three stations, and every report can be downloaded from the customer portal for the lifetime of the product.

Low-visibility performance is checked against CAT III requirements.

What it means for maintenance teams

Because each report is tied to a serial number, a replacement light can be compared with the one it replaces. Maintenance teams see drift long before it becomes a NOTAM.
