This is the voltage inverter where two cold cathode tubes can be connected to it. Cold cathode tubes and inverters can be bought at Sim Lim Square. If I remember correctly, I bought them for less than $30.
I stick the 2 tubes that I have got inside the panel of my lighting. These tubes won't look bright when the surrounding is bright. And when it is dark, it will give a dim blue glow as shown in my first few post in this thread. That's why it is not like fluorescent tubes or what.
Hope you guys enjoy it!
