# Projector

![](/files/flrMTg8o2pFH41kOwnIx)

I have covered projectors in depth in [another article](https://github.com/laserpilot/Guide_To_Projectors_For_Interactive_Installations/blob/master/Guide%20to%20Projectors%20for%20Interactive%20Installations.md) (it is from 2014, so it needs an update as well) so I won’t go into detail with them here.

It is important to remember that they are not much more than a fancy implementation of a light source, an imaging element and a lens. They are best for darker environments, but they tend to be the most economical choice for large scale imagery. It is also easier to blend multiple projectors together more seamlessly.
