EX99-LED
UL Hazardous Location Process Light
Explosion-Proof LED Lighting for Critical Process Visibility
The EX99-LED is a UL-listed hazardous location LED luminaire engineered specifically for process sight glasses, flow indicators, manways, and environmental chambers. It delivers powerful, focused illumination while operating safely in Class I hazardous areas, where flammable vapors and gases are present.
Where the EX99-LED Is Used
The EX99-LED is designed for direct viewing of live process conditions, including:
- Sight glasses
- Sight flow indicators
- Manways
- Environmental chambers
- Beverage and pharmaceutical process lines
- Chemical and solvent handling systems
These are environments where condensation, heat, vibration, and flammable atmospheres destroy conventional lighting — and where visibility is mission-critical.
Hazardous Location Certification
The EX99-LED is UL 844 Listed for hazardous locations:
Approved Locations
- Class I, Division 1, Groups C & D
- Class I, Division 2, Groups C & D
- Temperature Code: T6
This means the fixture is certified for environments containing ethylene, hydrogen, propane, gasoline vapors, and similar flammable gases — even during normal operation.
Why This Light Is Different
Unlike ordinary industrial LEDs, the EX99-LED is designed as a true process instrument, not just a lamp.
Thermal Management Structure (TMS)
The EX99 offers a patented Thermal Management Structure actively pulls heat away from the LED engine and electronics, extending life and ensuring safe surface temperatures in explosive environments.
CREE™ COB LED Engine
High-power CREE chip-on-board LED delivers:
- 1300 lumens
- >93 lumens per watt
- 4000K neutral white (This produces bright, natural-looking illumination that makes fluid clarity, bubbles, color changes, and contamination easy to detect)
COB (Chip-On-Board) means that many microscopic LED chips are bonded directly onto a single thermal substrate, forming one large, uniform light-emitting surface instead of dozens of tiny LEDs scattered across a board.
So instead of seeing:
- Individual LED “dots”
- Harsh glare
- Uneven light
You get one bright, smooth, optical-grade light source.
Optical Performance
The EX99-LED uses high-grade optics to produce a 26° beam angle (FWHM), delivering tight, concentrated light exactly where operators need it inside the process window, not scattered into the room.
This is ideal for:
- Flow verification
- Foam detection
- Particulate visibility
- Color and turbidity inspection
Industrial-Grade Construction
The housing is cast aluminum, precision machined, with two physically isolated compartments:
- Electronics compartment
- Wiring compartment
This prevents heat, electrical interference, and wiring faults from affecting LED performance and improves safety, reliability, and service life.
The viewing window is borosilicate DIN 7080-16 glass, the same high-temperature, chemical-resistant glass used in industrial sight glasses.
Electrical Performance
The EX99-LED is engineered to be plant-friendly and grid-stable:
- Input Voltage: 120 / 240 / 277 VAC
- Frequency: 47–63 Hz
- Power Factor: > 0.9
- Total Harmonic Distortion: < 20% at full load
This means low electrical noise, low losses, and compatibility with plant power systems.
