20 & 28-inch Phenomenon Lightning Plasma Tubes

When it comes to plasma lamps, the bigger the better. We have already covered plenty of impressive plasma toys here. These 20 & 28-inch Phenomenon Plasma Tubes are also worth a look. They were made a couple of decades ago. The design seems to be inspired by thermometers. You can put these on your desk or hang them on the wall.

These plasma lamps are not sound reactive but look still trippy. They can excite neon and other gases.
