When ordering the XVBC35 from Schneider Electric it does not include the bulb which has to be purchased separately. The datasheet lists the bulb type as Incandescent BA 15d
Protected LED. The link below will take you to what we carry in that bulb type. Please use the filters and datasheets to further narrow down the choices according to your needs and choose the one that best suits your application.
