I would easily pay 30+ USD per bulb if it had time-sync and NO internet connection (LAN optional and not a must-have).

Actually I already did. LIFX day night bulbs cost more than that and don't have the functionality that you had in your product out of the box.

Actually personally I would pay as much as 50 USD per bulb for standalone bulbs that just follow a cycle pre-set by myself over BLE or wifi or even a freaking USB port :p

Maybe they exist but I haven't been able to find them.
