The current IP68 dustproof and waterproof can ensure the safe and stable operation of portable explosion-proof searchlights in harsh weather conditions. When using a handheld explosion-proof searchlight, it is necessary to check whether the various components of the searchlight are tightly connected to ensure good waterproof, explosion-proof, and impact resistance performance.
