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
