Recently, I've been using LED floodlights, normally 2 or 4 of them. It depends on the venue. 4 lights need a proper blackout, but this is not always possible to achieve. Most often, all the lights are in my car, and it's up to me how many of them to use.
I bought my small plastic case light in the "Light and Music" chain store. Right now, each one costs about 5 thousand rubles. You know that prices are constantly changing, so do not rely on this figure.
The lights are connected to the mains; the lights must be installed before the performance, do not forget about it.
The lights are to be installed on the floor. If you need 4 lights, I place them on the carpet corners, all of them pointing at me. If it's 2 lights, then I just put them on both sides.
