Here is the reflector inside my 70 watt high pressure sodium G.E. M250R2. The lamp installed is a Philips Alto. One can tell by the green dimple at the top of the lamp.
the current ones don't have that dimple anymore. BTW I see you have the socket set for Type III distribution. I prefer Type II since I think the lamp looks better with the arc tube centered in the reflector.
The lamp socket was set like that by G.E., I haven't adjusted it.
