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 is continually improving existing lighting systems and developing 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 testsGeometric Measurement A measuring projector is used to check the filament geometry - with regard to the statutory standards in accordance with IE C 60810. The filament must be dimensionedand 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 HELL A bulbs over a long period. Vibration and Shock Test Here, 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 G such as the PY 21W for example G is tested in a climate chamber at different temperatures and air humidities. Optimum adhesion of glass bulb paint guarantees the prescribed amber indicator light over the whole service life period.Light Flux Measurement The Ulbricht sphere and goniometer are used to determine the light fluxes and luminous intensities of the HELL A bulbs. This guarantees optimum light output of the bulbs.BULB T4-5/8BULB T4-5/8 12V 15WBULB T4-5/8 12V 15W SV8.5-8Glove Box Light BulbMulti Purpose Light Bulb
