LED technology is certainly improving and will no doubt be THE choice in the future. We do need to remember a couple of things, though...
The life expectancy of a CF is when it stops working - full bright one day and full dead the next. The life expectancy of an LED is when the lumen output has dropped to half what it was when new. This can skew ROI numbers. A customer will want the bulbs replaced when the room is too dim, not when some paper says time is up. I really do wish LED manufacturers would publish their charts!
One must also look at lumens per watt per dollar. CF bulbs still rule that roost, although LED bulbs are catching up fast. Lee Cordochorea
