A good point. I just checked - the CRT draws about 120W and the 40" LCD about 70W. The latter is more than I expected, given that it's not particularly big by modern standards - though it is a few years old itself by now.

LCD monitors have strong backlights but most of it is lost. You have diffusers, polarizers, color filters, opaque elements between pixels, and this is before the blocking done to construct the final image. I think the overall intensity loss is over 90%.
