Please suggest some thing other than Oriel and Lumina Power. We have a 450 W Xe lamp but the power supply is not working. So need to buy an power supply with the igniter/ignition box.
Try Jobin Yvon Horiba (lately the name changed to Horiba Scientific). They may still have laying around the high voltage power supply that is connected to the Spex Fluorolog Spectrofluorimeter that is using a 450 W Xe lamp.
The other option is Hamamatsu, their lamps are pretty good too.
