Explosion proof tunnel light is specially designed for underground tunnel illumination, industry plant and offshore oil plant, which has potential explosive atmospheres or combustible dust, sulfide or salt in the air.

Absolutely corrosion proof, explosion proof and waterproof, the tunnel light is a very good item for coal mine, metal mine and offshore oil plant;
As higher final output efficiency, it can replace the 200 watt halogen lamp, and reducing energy by 7 times. ( the energy you saved for one year using is enough to buy the lamp)
Very long lifetime, and no maintenance cost.

Housing material:

stainless steel with nickel plated, absolutely corrosion proof
bulletproof PC lens with antistatic oil painted, which can bear more than 20J impact, no need metal mesh as normal light

Light source:

6pcs American CREE LED, total power 30 watt, initial output lumens is 3000 lumens.

Life time: more than 50,000 hours

CRI: 78, color temperature: 6500K

Patented reflectors enable the lamp to illuminate the underground passage uniformly, 150 degree beam angle in longitudinal plane, and 120 degree in transverse plane


Input: AC85-265V, 50/60HZ, or DC24-36V, no critical to voltage drops.
Total power consumption is only 30watt, .reducing energy consumption by 7 times.


water proof: IP67

Corrosion proof: WF2

EXD IIB T4 (for Zone 1 and 2, Zone 21 and 22 )
