That's surprisingly low. I would have expected much higher since I have been told that a bedside dimmer light is a US custom. It isn't a UK one at all as far as I know. I'm in the UK, and I would guess that it is even lower here - close to non-existent outside of smart-home and IoT enthusiasts, and US expatriates.
