VL-EXLED52-2LL Explosion-Proof LED Linear Light for Hazardous Locations
The VL-EXLED52-2LL Explosion-Proof LED Linear Light is a twin-tube industrial luminaire delivering high-uniformity ceiling illumination for Class I Division 1/2 and ATEX/IECEx Zone 1/2 classified environments. Building on the proven VL-EXLED52-1LL single-tube platform, the -2LL variant houses two LED tube modules in a single explosion-proof aluminum body — doubling lumen output while maintaining the same compact footprint. Designed for surface-mount or suspended installation, the VL-EXLED52-2LL is the high-output choice for wide-span process aisles, compressor buildings, and industrial workshops where single-tube illumination is insufficient to reach OSHA and IES recommended illuminance levels.

Frequently Asked Questions
- What is the difference between VL-EXLED52-1LL and VL-EXLED52-2LL?
- The VL-EXLED52-2LL is a two-tube version of the VL-EXLED52-1LL, providing approximately double the lumen output (5,200–10,400 lm vs. 2,600–5,200 lm) in the same 1,200mm length. The 2LL housing is 100mm wider (220mm vs. 120mm) to accommodate the second LED tube and driver. Both versions share identical certifications, beam angle, and mounting hardware.
- How many VL-EXLED52-2LL fixtures are needed to replace a row of 4-lamp T8 fluorescent shop lights?
- A standard 4-lamp 32W T8 fluorescent industrial fixture produces approximately 10,000–11,000 lumens at initial output (declining to ~7,500 lm at end of 30,000-hour rated life). The 80W VL-EXLED52-2LL provides 10,400 maintained lumens at 50,000 hours — a one-for-one replacement ratio with superior maintained illuminance over the fixture’s life. Energy consumption drops from ~132W (4×32W + ballast) to 80W.
- Is the 0–10V dimming interface compatible with standard DALI ballast controllers?
- The VL-EXLED52-2LL uses analog 0–10V dimming, not DALI digital dimming. It is not directly compatible with DALI controllers without a DALI-to-0–10V converter. Most modern building automation systems offer 0–10V outputs natively. For facilities using DALI, a DALI-to-analog converter (e.g., Helvar DALI dimmer) provides bridge compatibility.
- Does the -40°C rating apply to the LED driver as well as the LED module?
- Yes. The VL-EXLED52-2LL is rated for -40°C to +60°C for the complete luminaire assembly including the LED driver (power supply). The driver uses components rated for cold-start operation at -40°C. Lumen output may be slightly higher at cold temperatures versus rated output at 25°C — no warm-up period is required as with HID sources.
