VL-EXLM9223-XXX Tri-Proof Explosion-Proof Street Light for Hazardous Locations (120W–180W)
[rank_math_toc]Explosion-proof for Hazardous Locations
The VL-EXLM9223-XXX Tri-Proof Explosion-Proof Street Light is a high-output road and perimeter luminaire rated for Class I Division 1/2 and ATEX/IECEx Zone 1/2 hazardous environments. “Tri-proof” refers to its three combined protections: explosion-proof, dustproof (IP66), and waterproof — making it suitable for outdoor perimeter lighting at oil terminals, LNG facilities, chemical plant fence lines, and offshore platform deck lighting. Available in 120W and 180W, the VL-EXLM9223 delivers up to 23,400 lumens from a Type II or Type III street-light distribution pattern optimized for road, pathway, and perimeter fence illumination in classified industrial sites.

Perimeter Lighting Design Guidelines for Classified Sites
Industrial site perimeter lighting in classified areas must comply with both photometric requirements (IES RP-28 for security lighting or API RP 500 for oil facilities) and hazardous area electrical standards. Key design parameters: (1) Pole-mounted fixtures must maintain the classified-area boundary — if the fence line is within a Zone 2 or Class I Div 2 area, all pole fixtures require explosion-proof rating. (2) Underground conduit must be sealed where it transitions from classified to unclassified areas. (3) Photo-controls and dimming controls must be located in non-classified areas or must themselves be rated for the classified area.
Application Environments
- Oil Terminal Tank Farms: Perimeter and internal road lighting within Class I Div 2 fence boundaries
- LNG Facilities: Roadway lighting within NFPA 59A classified boundary zones
- Chemical Plant Sites: Internal access roads and parking lots in classified perimeter zones
- Offshore Platform Deck Lighting: Helideck approach and structural perimeter light poles in Zone 2
- Refinery Internal Roads: Primary and secondary roadways within API RP 500 classified boundaries
Frequently Asked Questions
- What does “tri-proof” mean for the VL-EXLM9223?
- “Tri-proof” refers to three combined protective ratings: (1) explosion-proof — flame containment per NEC/ATEX standards; (2) dustproof — IP6X complete dust exclusion; and (3) waterproof — IP6 protection against high-pressure water jets. Together these ratings qualify the fixture for the full spectrum of outdoor hazardous area challenges including rain, wash-down, saltwater spray, and combustible dust accumulation.
- What pole height and spacing achieves 20 lux average for a service road?
- For a service road 8m wide, 180W VL-EXLM9223-XXX units on 10m poles at 35m spacing achieve approximately 20–25 lux average with a uniformity ratio (Emin/Eavg) of ≥0.3 — meeting IES RP-28 Class P1 security lighting requirements. Photometric calculations for specific pole heights and road widths are available on request from Veilux engineering.
- Is the surge protection adequate for exposed industrial pole installations?
- Yes. The integrated 10kV/10kA transient voltage surge suppressor (TVSS) per IEEE C62.41 Category C3 handles the high-energy surges common at outdoor industrial sites including those near large motors, capacitor banks, and lightning-exposed locations. For sites with extreme lightning exposure (IKL IV), an additional Type 1 SPD in the distribution panel is recommended per NFPA 780.
- Can the VL-EXLM9223 be controlled by a wireless lighting control system?
- Yes, via the standard 0–10V dimming input or NEMA 7-pin photocell receptacle. The photocell socket accepts any ANSI C136.41-compliant wireless node (Lumenade, Itron SL, Philips SRG) that fits the NEMA twist-lock receptacle. The control node itself must be rated for the classified area if mounted on the fixture; alternatively, install it on the non-classified side of the area boundary using a remote-dimming control cable.
