Good point. But, take it one step further and compare them to LED based bulbs. Not the LED's in a modem but direct plug-in replacements for incandescent bulbs:

You might find them to be a bit pricey but they are now at the price Compact Fluorescent lamps were at a few years ago. My electric bill for last month was over $300. I just filed a complaint with the CPUC, again.

Your numbers are way off. Looking at a 100 watt light bulb, it gives off 1710 lumens, and at 0.0015 lumens/watt means that the incandescent bulb is about 2.6% efficient. A compact fluorescent bulb that I have puts out 1600 lumens for 23 watts input making it about 10.4% efficient.
