There’s much to be said for better worklights! For any usage scenario, optimum light conditions are essential to be able to work faster, more precisely and productively at twilight and in the dark. HELLA’s worklights take care of this thanks to their reliable quality. Stronger and better working light helps. Sleep researchers* in Basel working together with scientists from the Fraunhofer Institute for Work Management Organisation have discovered that people react strongly to light. For example, the colour temperature of lighting has a considerable influence on responsiveness and...

Introduction | 05 Halogen worklights: The established standard. HELLA has continually been improving the design of its halogen worklights for many decades. The challenge: halogen light sources generate a great deal of heat. This heat can only be dissipated if the headlights have a relatively large mounting depth. In order to still be able to offer the customer compact worklights, HELLA developed housing and disks made of synthetic material with a higher heat resilience to enable smaller headlights to be constructed with the same power. Xenon worklights: A leap in quality. The use of xenon...

08 | The technical lighting concept What the lumen output says about the brightness and light of a worklight. The luminous flux emanating from a light source is measured in the physical unit of lumen (lm), reflecting the varying sensitivity of the human eye to light. The lumen output of a light indicates how brightly the light it produces is perceived. That makes lumen output a better reference than the wattage, which only indicates the power consumption of a light but not how much brightness it actually produces. To aid easy comparison, the following overviews therefore list the lumen...

More light, less consumption! A meaningful evaluation of a light's power sees the lumen output in relation to the wattage required to produce the desired brightness. Modern LED technology achieves a particularly good balance in this regard. The energy efficient lights reduce the strain on the generator, which is particularly useful for older tractors with limited generator power. In general: Lower fuel consumption in relation to light intensity makes energy efficient worklights economically sound in the long term, especially in the light of constantly rising fuel costs. How many watts...

10 | LIGHT INTENSITY IN THE CLOSE RANGE Light intensity in the close range An overview of our worklights, ordered by light intensity. The higher the lumen output, the brighter the worklight. The direct comparison aims to help you find just the right worklight for your close-range requirements - with high, medium or low intensity depending on the lumen output.

Light intensity in the close range | 11 Medium light intensity More light with lower wattage: LED achieves around four times greater luminous efficiency than halogen, at the same generator load. In addition, an LED light with 1,200 lm appears considerably brighter to the human eye than a halogen light with 1,200 lm. Brightness perception This is due to the different colour temperatures of LED and halogen light. Halogen worklights with 1,200 lm, colour temperature 2,400 Kelvin LED worklights with 1,200 lm, colour temperature 5,7

12 | LIGHT INTENSITY IN THE FAR RANGE Light intensity in the far range An overview of our worklights, ordered by light intensity. The higher the lumen output, the brighter the worklight. 4,500 lm The direct comparison aims to help you find just the right worklight for your far-range requirements - with high, medium or low intensity depending on the lumen output.

LIGHT INTENSITY IN THE FAR RANGE | 13 Lumen Modul 70 LED Gen. iV 1G0 996 476-01 1 2,500 lm Luminous efficiency compared The brightness of a surface is dependent on two factors: 1. Lumen output (= emitted light) 2. Beam angle (= distribution of emitted light onto surface) The more lumen a light source has, the brighter the emitted light. The oncoming brightness on a surface is, however, determined by the beam angle of the reflector. Higher beam angles illuminate larger areas but are less bright. Example of luminous efficiency: A worklight with 2,000 lm distributes its light onto 12...

Agricultural and forestry vehicles The targeted deployment of efficient worklights, particularly in agricultural use, dramatically increases efficiency. Modern owner-operators can work at full capacity at night and in twilight – older machinery can be used more efficiently by optimising its lighting. The extremely homogeneous illumination of HELLA worklights ensures ideal working conditions and a relaxed working environment.
