All the advantages of modern LED lighting technology are optimally employed in HELLA Work Lamps. The choice of LEDs, the power supply and thermal management of the headlight are key factors in achieving optimum light output (lumen). The quality of the components used by HELLA ensures, for example, that the light remains at the same level of brightness at high ambient temperatures. Good thermal management is necessary to ensure the long service life and the cost-effectiveness of an LED Work Lamp. The reason for this is that as soon as an LED is illuminated, heat is produced. The more current that is supplied to the system, the more heat is produced by the LED. The higher the LED temperature, the lower the light output and the shorter the service life. The heat must therefore be dissipated into the environment. HELLA uses the latest simulation programs during product development to ensure optimal heat dissipation through the housing. LED Work Lamps from HELLA are also equipped with thermal sensors to provide reliable protection again the LEDs overheating. This guarantees extremely long service life of up to 60,000 hours, as well as consistent light output.
