A system comprising: a first light source configured to emit a first given colour of light; a second light source configured to emit a second given colour of light, the second given colour different from the first given colour, respective spectra for each of the first colour and the second colour overlapping with each other; a light integrator comprising: at least one body configured to integrate light, the at least one body comprising a respective length and a light egress end; a first light entrance device comprising a first light entrance face, the first light entrance device located distal the light egress end; and a second light entrance device comprising a second light entrance face parallel the first light entrance face wherein the first light entrance face and the second light entrance face are facing in opposite directions; each of the first light entrance device and the second light entrance device configured to receive light and deflect the light into the at least one body and towards the light egress end; and, a beamsplitter system (360, 370-1, 370-2) configured to about equally distribute light from each of the first light source and the second light source to each of the first light entrance face and the second light entrance face, the beamsplitter system (360, 370-1, 370-2) comprising a beamsplitter, a first mirror at the first light entrance face, and a second mirror at the second light entrance face, the beamsplitter configured to: transmit half of the first given colour of light from the first light source to the second mirror; reflect a remaining half of the first given colour of light from the first light source to the first mirror; transmit half of the second given colour of light from the second light source to the first mirror; and, reflect a remaining half of the second given colour of light from the second light source to the second mirror, the first mirror configured to: reflect the remaining half of the first given colour of light from the first light source into the first light entrance face; and reflect the half of the second given colour of light from the second light source into the first light entrance face, the second mirror configured to: reflect the half of the first given colour of light from the first light source into the second light entrance face; and reflect the remaining half of the second given colour of light from the second light source into the second light entrance face, such that the light from each of the first light source and the second light source is about equally combined at each of the first light entrance face and the second light entrance face, and the light entering both of the first light entrance face and the second light entrance face has the same characteristics with regards to at least colour and intensity. a first light source configured to emit a first given colour of light;
