Yes. Our outdoor LED screens have IP65 waterproof rating. But we suggest regular inspection of the waterproof seal to avoid water leakage.

Outdoor screens have higher brightness and waterproof housing. Indoor models feature lower brightness, fine pixel pitch and no need for waterproof protection.

The theoretical lifespan is 50,000–100,000 hours. Actual service time depends on working environment, temperature and daily maintenance.

Yes. A sending card and receiving card system is required to transfer video signals and control screen content playback.

Pixel pitch is the distance between two adjacent lamp beads. Smaller pitch means higher resolution. Choose according to your viewing distance and budget.

LED technology is energy-saving. Power consumption changes with brightness. Average power is much lower than traditional advertising light boxes.

Yes. We supply warranty service and remote technical support. Overseas projects also support guidance for local engineers to repair.
