LED vs Halogen - beware LED claims!

I have conducted a detailed comparison between LED and halogen lamps and the LED's may last a long time and have very low power consumption, but the light output claims are often wildly optimistic.

The toxic substances issue needs to be addressed too. Though I'm a bit more circumspect about mercury than most people. Still, it's another part of the benefit/detriment equation.
I wonder if everything from raw materials & manufacture to end-of-life disposition are factored in, how the various lighting methods compare. Is such a "big-picture" evaluation even possible or practical?
