When it comes to driving safety, sight is the most important sense.
Visibility can be impaired under various circumstances, and driving under these adverse conditions will increase the risk of an accident.
To meet these challenges, HELLA continually improves existing lighting systems and develops new lighting equipment and components.
HELLA bulbs undergo strenuous quality tests.
This is achieved by using the most modern equipment in light metering, which provides information if a bulb has the necessary properties.
Hella products are subjected to the following tests: Geometric Measurement: A measuring projector is used to check the filament geometry with regard to the statutory standards in accordance with IEC 60810.
The filament must be dimensioned and positioned within the bulb as specified in the standard.
This is the only way to achieve optimum headlight power and prevent glare to oncoming traffic.
Life Test: Sophisticated tests are used to prove the high reliability of the HELLA bulbs over a long period.
Vibration and Shock Test: Here, the vibration resistance of the bulb and the filament in particular is tested on an electrodynamic vibration table.
Paint Adhesion Test: The adhesion of paint on colored glass bulbs, such as the PY 21W for example, is tested in a climate chamber at different temperatures and air humidities.
Light Flux Measurement: The Ulbricht sphere and goniometer are used to determine the light fluxes and luminous intensities of the HELLA bulbs.
