VL-EX8197D Explosion-Proof Double Linear LED Light for Hazardous Locations
The VL-EX8197D Explosion-Proof Double Linear LED Light is a dual-tube industrial luminaire providing high-output ceiling illumination for Class I Division 1/2 and ATEX/IECEx Zone 1/2 hazardous environments. With two parallel LED tubes in a single housing unit, the VL-EX8197D delivers 10,000–15,000 lumens from an 80W–120W draw — equivalent to replacing two 150W fluorescent hazardous-location fixtures while eliminating UV emission, mercury content, and the maintenance burden of fluorescent tube replacement. The rigid die-cast housing provides mounting points for both surface-ceiling and suspended installation, with sealed polycarbonate diffusers ensuring even light distribution across process aisles, machinery bays, and inspection workstations.

Frequently Asked Questions
- How does the VL-EX8197D differ from the VL-EX8197S?
- The VL-EX8197D is the double-tube version of the VL-EX8197S, providing approximately twice the lumen output (10,000–15,000 lm vs. 5,000–7,500 lm) in the same 1,200mm length. The D variant is 280mm wide versus 150mm for the S. Both share identical certifications, mounting hardware, and wiring configurations.
- Can the VL-EX8197D replace existing 2-lamp T5HO fluorescent fixtures in Class I Div 1 areas?
- Yes. The VL-EX8197D is a direct physical and electrical replacement for 2-lamp 54W T5HO or 4-lamp 32W T8 explosion-proof fluorescent fixtures with equivalent or greater lumen output. The mounting bolt pattern and conduit entry locations are compatible with most Class I Div 1 fluorescent fixture mounting templates.
- Is the VL-EX8197D rated for T4 temperature class?
- Yes. Both ATEX and IECEx certifications specify T4 surface temperature class (maximum surface temperature ≤135°C / 275°F), suitable for gas groups with auto-ignition temperatures above 135°C including propane (468°C), methane (537°C), and ethylene (425°C).
- What wire gauge is required for the VL-EX8197D?
- At 120V, a 120W load draws approximately 1.0A (or 0.5A at 277V). Minimum 14 AWG THWN-2 conductors are suitable for branch circuit wiring. For conduit runs exceeding 100 feet, upsizing to 12 AWG is recommended to limit voltage drop below 3%. Conduit seals per NEC 501.15 are mandatory in Class I Div 1 installations.
