Might look expensive but this is the new generation that apparently claims 800lumens
I say apparently because this post on the offical yeelight forums which was confirmed by the rep that it may not be 800lm.
Main changes from previous generation:
Voltage (V): AC 100-240V (previously 220V only)
Luminous Flux: 800lm (previously 600lm)
Output Power: 10W (previously 9W)
Standby wattage: 0.5W (previously ~1.2W) - thanks hezuleh
Still has:
16m Colours
Color Temperature or Wavelength: 1700 - 6500K
Lifespan: 25000h
Looks nice
