what is the use of a lens compared to no lens (im not talking about theory but if the real world effect of these lenses it worth the bucks)? Or are they necessary to keep the led away from too much water in the air ?
im planning to do a 2x2space with 4 veros.
So my questions: is a lens mandatory or even worth the bucks ?If yes what lens in particular would you recommend?
