Although, it seems like very standard (everyone has it at home), it VERY tricky to make. The reason is for that is hot cathode instead of cold one. In cold cathode mode it's OK to use glue to seal tubes and connect feed through electrodes. It getting a little bit warm but it doesn't leak. Here the electrodes gets very hot. As this light bulb is 12Volt at 3 Amperes. (Which makes it 36 Watt bulb)
