Not that one. It is FTL that will fit the socket as the COLAMP2000. See how the two pins are different sizes:

I bought one of those FTL lamps about ten years ago, but I can't find it now. Maybe I sent it back when I found it did not fit through the reflector.
This are specs for COLAMP 2000 that I used when was playing with producing new ones:
type Projection Lamps
Length 140 mm
52000 lum (4141 cp)
Col.Temperature 3200 K
Voltage 240 or 220/230V
A 9.09 A (220V)
Av.Life 300H
Filament CC-8
40 x 7.5 (H x W)
Glass Diam 13/8 "
Base GY 16 2-pin
Light Center Length 3.35 inch (85 mm)
Maximum Overall Length 5.71 inch (145 mm)
Maybe that helps somebody.
Check focal point and filament size or reflector wouln't work correctly.
My bulb length checks out close to yours (just shy of 4" from the end of the bulb to the beginning of the white ceramic base) but the bulb diameter spec of 1 3/8" listed above for the COLAMP 2000 listed above seems wide to me and at this diameter this bulb would not fit into my reflector as I see it. My halogen bulb has a diameter of 0.9". I can also see how only about the top half of the halogen bulb physically goes "into" the reflector on my unit but I guess it gets the job done.
Colamp2000 are about 26mm in diameter and the hole in the reflectors about 32mm. The FTL bulges to about 36mm in the middle (see below). So it is very close, not much glass would need to be removed from the reflector.

Going back through this thread it really amazes me how time flies. Posts from 2009 seem like yesterday.
Anyway I did find one of my FTL (CP43) 2000W lamps I got in 2009 and it does indeed fit in the hole in my reflector without enlarging the hole.
So, it looks like there were two different versions of the FTL, one with the bulge and one without.
What I cannot answer right now is if the FTL (CP43) without the bulge is still in production.
The picture below shows two different FTL (CP43) lamps from different sources. Top one is 36mm, the bottom one is 26mm.

I have a Coolamp and/or Thorn, if you are interested?
