LED Explosion Proof Lights in Industrial Applications

I. Core Advantages of LED Explosion Proof Lights

Compared to traditional explosion-proof lighting, LED technology offers groundbreaking improvements:

• Energy Efficiency: 40-60% lower energy consumption (See Energy Efficiency Comparison Chart)
• Luminous Efficacy: 120-150 lm/W, surpassing metal halide lamps (80 lm/W)
• Vibration Resistance: No filament structure, withstanding 10G vibration levels
• Instant Start: 0.5-second activation, eliminating warm-up delays
