It's only an expensive led colorfull light🤨

The clock works well (with in-12 A or B tubes). It didn't come with any instructions so here are my own after some experimentation:Nixie IN-12 clock, 4 button instructions:Setting:Hold Menu Button to enter setting mode. Year will flash first.Set using + and - buttons to set. Press menu to go to next setting.Order of setting modes:YearMonthDayHour (set in 24 hour time)MinuteSecondsDay of week1) Interval between Digit Cycling to prevent Cathode Poisoning. Choose 0 to 30 minutes (0=no cycling)2) Turn off display timer (0 to 60 minutes, 0=Display stays on)3) 12/24 hour time display4) Zero Blanking (Turns off first digit when it reads zero) 0= Digit On / 1= Digit off5) Colon Blinking (1=steady on / 0=blinking)Day / Night Mode: Sets time to turn on in the morning and off at night to extend tube life (leave both at 00:00 if you don't want this function)My only concern is that the clock gets a little warm which shouldn't really happen with nixies. Only a day old, so will update if status changes.
