What Are the Typical Power, Lumens and Efficacy of Explosion-Proof Lights? Is Over 150 lm/W Common?

In hazardous areas (oil & gas, chemical, mining, pharma, warehouses), explosion-proof lights ensure safety and lighting. Key factors: power (W), lumens (lm), and efficacy (lm/W).

1.Typical Power Range

Modern units use LED. Power depends on height, area, and illuminance (50–200 lx).

• Small/portable: 10–50 W
• Medium (most used): 50–150 W
• High-power flood/high-bay: 150–300 W (up to 400 W+)

Quick guide:
2.5–4 m → 20–40 W | 3–6 m → 40–80 W | 6–10 m → 80–150 W | 8–12 m+ → 150–300 W
Use calculation software and maintenance factor in projects.

2.Typical Lumen Output

Lumens ≈ power × efficacy (110–140 lm/W):

• 20–30 W: 2,200–4,200 lm
• 50–60 W: 5,500–8,400 lm
• 100 W: 11,000–14,000 lm
• 150 W: 16,500–21,000 lm
• 200 W: 22,000–28,000 lm

A quality 150 W unit ≈ 21,000 lm (replaces 400 W metal halide). CRI ≥70–80, CCT 3000–6500 K.

3.Efficacy: Is >150 lm/W Common?

Mainstream: 100–130 lm/W; premium 120–140 lm/W.
150 lm/W is uncommon. Thick housing, glass, sealing, and T-class limits reduce system efficacy. Lab chips go higher, but certified fixtures rarely exceed 140 lm/W. Check whole-fixture reports, not claims.

4.Selection Tips

• Prioritize real efficacy and lumens over wattage.
• Verify Ex marking, T-class, IP66, corrosion grade.
• Good heat dissipation, ≥50,000 h life.
• 100 W LED replaces 250–400 W traditional lamps, saving energy and maintenance.

LED versions cut energy 50–70 %, last longer, start instantly, and run cooler.

5.Summary

• Power: 20–200 W mainstream
• Lumens: 100 W ≈ 11–14k lm; 150 W ≈ 16.5–21k lm
• Efficacy: 100–140 lm/W; >150 rare

All their explosion-proof lights use LED technology with brand-new LED modules and special constant-current drivers. Every model is designed to deliver more than 150 lm/W. Higher efficiency means more light and less heat, so the temperature class stays at the safer T6 or T5 level.
