There's definitely value in that. Although it seems like LEDs don't disperse the light as much either. They tend to be a bit more directional. It probably isn't too bad, but it may make for some darker corners in your house.Applying that to MD's other numbers, a CFL is still more cost-effective, but not by a lot (around $10). $10 over 30,000 hours of use seems like an easy price to pay for more eco-friendly.
