Crackle Tubes are available in two varieties:
Classic Crackle Tubes:
This type of crackle tube has been made since early in the 20th century. It is filled with thousands of pieces of small, cut-glass tubing used to break up the gas discharge into fast-moving lightning-like shapes. Filled with neon gas, the light display is a bright Orange/Red. It is also possible to fill to fill with Argon (Pastel Purple) or Krypton (White) as well. These tubes are powered by traditional older “core and coil” style transformers instead of the newer electronic neon power supplies.* These transformers are becoming harder to find and require two wire connections to the tube.
Variable Speed Crackle Tubes:
Developed by Strattman Design, this newer type of crackle tube is filled with small glass beads coated with phosphors to create the same crackling lightning-like effects in a wider range of colors. Blue or White will look like realistic lightning, but Green, Red or Purple are also available! These lighting displays run off of a 12 volt DC wall adapter and use very little power, usually less than 12 watts. The speed of crackle is manually adjustable. These tubes only require one wire connection. Additional circuitry can make the tube crackle with music or other sounds (such as with sound effects in Halloween displays.) Only one wire connection is required for this type of crackle tube.
Available in lengths up to 6 ft and a wide variety of diameters. For custom sizes not listed please inquire for more info.
* “Core and coil” style transformers for Classic Crackle Tube require two wire connections to the tube
Also Available: Crackle Globe! Pricing on request.
Unlike plasma globes with only gas inside, crackle globes are also filled with many small glass beads that the plasma discharge randomly travels through, creating a multi-layered lighting effect.
