The universal lamp holder is screwed onto the Tesla coil with its M4 thread. After that, any lamp with an E27 thread can simply be plugged in. On the one hand, this allows the lamp to be held securely and the lamp to be changed in seconds. There is no more elegant way to attach your lamps to a Tesla coil.
Delivery without lamp!
When used with the 230V Tesla coil, the power of the SSTC must be reduced. Either with a variable transformer or conveniently with a staccato controller.
