The lamps avalable for the
fixture would be the Osram HMP 575w/DE #54144 which replaces the
HMI 575w/GS most would be looking for.
Othewise the new HTI 575w/D4/75 which will be coming on the market soon.
Other lamps would be the Philips MSI 575, Ushio UMI 575/GS, GE CMR 575/DE or Koto DI-6 if Koto starts producing their own lamps again.
The lamp is a seperate component from the
reflector assembly which would come from
Altman.
In reading the
manual I found this curious:
"Under no circumstances should you attempt to remove the lamp from the
reflector assembly. The lamp and
reflector assembly is prefocused at the factory for optimum performance.
Return the entire assembly to your
Altman Satellite Dealer.
I now see the problem you have. It would seem that by the
manual you need to
return your
reflector to an
Altman dealer and have them either get you a new
reflector/lamp or
return yours for a new lamp to be installed.
Otherwise in the parts
manual I see two part numbers. One for the assembly w/o lamp #76-0372, the other for it with the lamp installed #77-0090. I would than take it for granted you can get the assembly w/o lamp by ordering that part number. Given it's in the
manual that they will
bench focus the lamp for you on the other
hand, it is what I would recommend instead of doing it yourself.
Don't know if it will work but I copied from the PDF on the
Altman web site and asked a buddy of mine to create a pdf of the information relating to your
followspot.

Otherwise, you can just go to the
Altman website, look up the follow spot under parts lists Catalog/
page #77-0090 Satellite Lamp Assy. which is
page 130 of the parts
manual otherwise.
