Im looking into making some glass bottle table lamps for personal use and the possibilities of selling as a sideline business all going well.
Rather than importing power cord sets from overseas and having the incorrect plug/voltage etc, i was thinking of buying cord sets and lamp holders in NZ and repurposing to fit the bottle.
By doing it this way, does anyone know if there are any safety requirements or regulations that ill need to consider beforehand? All wiring will be done by a certified electrician.
