Plasma lamp

Most commonly, Plasma lamps are available in spheres and cylinders. Although there are many variations, a plasma lamp is usually a clear glass orb, filled with a mixture of various gases at low pressure, and driven by high frequency alternating current at high voltage (approx. 35 kHz, 2--5 kV), generated by a high voltage transformer.

Placing a hand near the glass alters the high-frequency electric field, causing a single beam to migrate from the inner ball to the point of contact. An electric current is produced within any conductive object near the orb, as the glass doesn't block the electromagnetic field created by the electric current flowing through the plasma (though the insulator does block the current itself).

wow these things are amazing lol i never saw a plasma lamp man anyone tell me where can i buy it in india?

[aciolan]

@saiyan0gohan check ebay

[nuhvok01]

You are readin the wikipedia article word for word lol.

[F1RE3RR0R]

i just got one :p there amazing XD

[LethalMetalHead]

@MrAmmonation mostly true that.. when i was small i always said to myself'' if i crush that glass the plasmabeams will spread all over my room and i'll get killed D: xD

[MrAmmonation]

@LethalMetalHead lol i wanna try it but probally nothing will happen

[MrAmmonation]

@nuhvok01 lol yeah your right

[LethalMetalHead]

anyone else but me that wonder what happens if you crush the glass? xD

[DeadlyTeaParty]

Tee hee I bought one today!! XD

[vampiress49]

Hey... I bought one of those a few days ago at a yard sale for 25 cents....

want to know how to burn out the circuit in your plasma lamp? place two open circuit windings at the top of each other around the lamp sphere and connect a light emitter diode between only one wire end of each coils, it might not work for you but it did to me.

Nice. What's the music?

[zpopcornpawz]

Just got one of these.
