The most common xenon lamps are HPS lamps (high-pressure sodium gas lamps) and MH lamps (metal halide lamps). The principle of both is that the current arc passes through the two poles and ignites the gas to emit light (HPS uses sodium gas and MH uses a mixture of mercury and halide).
The light produced by both is full spectrum. The high-pressure sodium gas lamp has more red light and the metal halide lamp has more blue light. The growers usually choose different lamps at different growth stages of plants.
As for the cultivation of cacti, metal halide lamp is more applicable, because cacti have no specific flowering stage to observe, and blue light can promote their better and stronger growth.
