Mixed street light sources electrical design?

Hi All, 

Can we electrically design  mixed street light sources on the same circuit for example LED and SON lamps?

  • Yes,  and we often do when the circuit is covering  a mixture of terrain - narrow alleys for pedestrians need different lighting to a main road and that is different near a junction or crossing. If in doubt allow each fitting to have a local fuse/isolation point rather than grouped.
