This product has a large area for cooling and a good pressure resistance capacity. Inside, it is equipped with explosion-proof equipment and discharging resistors. It is convincingly safe, is good at self-healing, and has a long lifespan. Its tolerance is very small. Neither will it cause the overshooting of short-circuit current, nor the shortening of its lifespan. This product is specially made for the metallic halide lamps.
