You can choose between the following digit-heights: 20mm, 38mm, 57mm and 100mm.
The digits are LED digits in the brightest available version (Hyper-Red 660nm).
This guarantees a good visibility even under bad circumstances.
Self-illuminating digits like LEDs are much better when it comes to visibility and
signaling than reflective systems like LCD for example. Therefore we only use LED technology in our HvG displays.
The reading distances resulting from the digit-heights can be found underneath the digit pictures.
