Very nice project Dimitris,this will be one of my favorites to build this winter.
you have to do someting these dark days.

Note: this is easy to use in case someone has a fishpond filter or aquaria in the house as extra safetywarning in case off leakage.

hope you will have some lightning today

kind regards Chris
