| Manufacturer's article number | 0021071 | ? Manufacturer's part number. |
| Beam angle | 25° |
?
The wider the light beam, the larger the illuminated surface. Brightness decreases as the beam widens, since the light is divided over a larger area. For creating high contrasts it is therefore recommended to apply smaller light beams. However, contrasts that are too high can be distracting and can cause adjustment problems for the eye, which can be tiring. On the other hand, too little contrast creates a dull and flat impression. |
