MV lights are old tech and as someone else pointed out, high pressure 
sodium are more efficient.  However, I went with a couple of CFL floods 
to illuminate the area in front of my shop and I'm pretty happy with 
them.  I'm using two outdoor rated floods in a more or less standard two 
lamp floodlight fixture with a photo cell.  I think the floods are 23 
watts each, and they put out what seems to be just about as much light 
as the old 175 watt MV fixture they replaced.  I have been running CFL 
lights outdoors in protected areas (but not enclosed fixtures) fixtures 
for six or seven years now and haven't had any problems with them not 
working in cold weather.  I have five or six little conventional 9 watt 
CFLs running in porch light fixtures on photo cells around the property 
and they seem to last just about forever.
