 Im Bild wurde auf die Glasscheibe ein Papier gelegt, um die Ausleuchtung der Fläche festzustellen. Rechts wurde die alte (24 LEDs), links eine neue Trägerplatine (48 LEDs) eingebaut.
 Die neuen Belichtungszeiten konnten aufgrund von Zeitmangel nicht genau festgestellt werden, werden sich jedoch im Bereich um 15-20 Minuten bewegen.

The goal was to double the number of LEDs from 48 to 96. This is intended to achieve more uniform coverage of the exposure area, as well as, of course, shorter exposure times.&lt;/p&gt;
