This is a bit misleading, since LED's can now achieve 90 lumen/watt efficacy and colour rendering greater than Ra 90. Their greater expense is also offset by greater life. Follow the developments with Philips LEDs if you're interested in the leading edge of commercially available LEDs. The technology is moving at a tremendous rate. Look at I agree with you in many respects, since in the right application fluorescent is better.
In office lighting, for instance, a fluorescent tube is a big light source. With an LED you're attempting to get equivalent light out of very small point sources. Controlling and limiting glare with fluorescents is much easier than controlling glare with LED.
However I believe the reality is that LEDs will have largely replaced fluorescents within 10 years, but are a temporary measure themselves. OLEDs are on the way, and have compelling advantages. Imagine a light source you can spray onto your room surfaces, and pass a small current through to make glow: now *that's* how to control glare.
