I just googled national grid UK smart light and there are dozens of stories from different news services. Just about all have a link to the lifx website to purchase a globe. I only spent a few minutes but this is a national story and from what I can tell lifx is the only supplier offering this green light function. Imagine the government start installing them for free like they do LED lights here. Could be huge. HUGE!
