Oh yes, I agree with the general point, that the Jevons non-effect in lighting is canceled by the Jevons effect in general energy usage, and that we can't expect energy efficiency improvements alone to reduce the latter. So there's an important point here: the benefit of energy efficiency improvements is not that it will get total energy usage down by itself (and thereby hit GHG targets), but rather, that it will reduce the total hit to consumption/utility that we experience when regulations disincentivize (GHG-emitting) energy usage.
