Allora...i miei dubbi erano fondati....questa e' stata la sua risposta 5 minuti fa....
Thanks very much for your interests of our items.
Regarding 4-90 degree led lens,it means you can adjust the viewing angle from 4deg to 90deg according to the distance between led & lens.
In this case,you can buy only 1pc lens to make the viewing angle to be 4 deg to 90 deg.
Hope the above information can make things clear for you.
Thanks in advance!
Best wishes

Direi che non e' affatto semplice o ci si inventa qualcosa o sono inutili....
