Depends what you're measuring. If you're measuring the actual cost of bringing your home up to a certain level of litness, yes, that all complicated matters considerably. But if you're measuring the amount that humans spend on lighting, it doesn't. A router may throw a bit of light into a room, but that's a side-effect; when someone spends £50 on a router, they never think "And 30p of that comes out of my lighting budget."
