The right lamp:
you will need 6000-6500k lamp with small arc
if you see only movies and don't use your projector so much you can see in the link the HTI 150 Style (Generic) 6500K 90V/150W GY 9,5 750h the arc is 4-5mm it cost $69.95 (you can use the projector 2h per day and it would last a year) .

you need to know that if you will use this lamp with the same reflector the light will only be 60-70% of the original lamp. (for me it is fine)
In the thread of YWH you can find better lamp but the ballast can work only with 220V.

So i need 6500k to get the colours right I am going to try to cut the glass reflector of the old bulb with a diamond electric tile saw and mount the new bulb inside if it will fit but still need power supply and balast
No!
Do not cut the glass try to remove it without cuting it
This is a UV IR glass
Try to remove the front glass you can use a 0.035mm-0.06mm filler (the one that adjust the valve in the car engine ,you can cut the filler if it's too big) then pull a littel the glass so the filler will get to the gap, move it and cut the RTV.
sorry for my English I speak Hebrew.
