That looks like an inverted can, which would rule out running any type
of energy saving retrofit lamp in that fitting, as it would overheat.
If you find one with an open rear, I would recommend the GE Genura
as a compact fluorescent replacement for 100W filament R80's.
The GE Genura is a long life fluorescent (as it has no electrodes
towear out), and actually has a higher light output than the 100W
R80 it replaces. They are damn expensive though, but still much
cheaper if you work out the saving over even part of the lamp's
rated life. They are floodlamps (very wide angle), not spotlamps.
Life depends on temperature, which is why you want an open-rear
fitting so it runs as cool as possible.
