EX LED High Bay 50W 4000K · 120 lm/W – ATEX Zone 1/2/21/22 – Delivery 14 Business Days

Why choose the EX LED High Bay 50W

Most LED high bays are not permitted in hazardous locations. This fitting carries full ATEX certification for gas and dust zones, meaning it can be installed legally and safely where standard luminaires are excluded. With a wide 85–305V input range, a Moso driver rated for -40 to 60°C, and a 5-year warranty, it is engineered for demanding industrial environments where reliability is non-negotiable.

• ATEX compliance: Certified for Zone 1, 2, 21 and 22, covering both flammable gas and combustible dust atmospheres, so the fitting meets statutory requirements without additional enclosures.
• Efficiency: At 120 lm/W and 50W, it replaces a 400W HID or incandescent fitting, cutting energy consumption by up to 87% with no reduction in working light levels.
• Build quality: Pure aluminium construction with IP66 ingress protection resists dust, high-pressure water jets, corrosive vapours and temperature extremes from -40°C to 60°C.
• Driver protection: The Moso driver includes over-current, over-temperature, over-voltage and short-circuit protection, reducing the risk of unplanned downtime in hard-to-access locations.

Where to use it

This 50W ATEX high bay suits low-to-medium mounting heights of 4–8 metres in classified hazardous areas: chemical storage rooms, solvent handling bays, grain silos, flour mills, paint spray booths, fuel depots and offshore utility spaces. At 6,000 lm with a 120° beam, it provides broad, even coverage suitable for workbench-level tasks requiring 300–500 lux in Zone 1 and Zone 2 environments.

What the specifications mean in practice

• 120 lm/W: Every watt produces 120 lumens of usable light, so annual energy costs are a fraction of those for the 400W fitting it replaces.
• IP66: Fully sealed against dust ingress and protected against powerful water jets, making it suitable for washdown areas and outdoor classified locations.
• 4000K: Neutral white light supports accurate task visibility and colour discrimination without the harshness of cool white, appropriate for inspection and process work.
• 50,000 hours: At 16 hours per day, the fitting runs for approximately 8.5 years before reaching rated end-of-life, significantly reducing maintenance entries into hazardous zones.
• 85–305V input: Universal voltage compatibility means the fitting works on any single-phase supply across the EU without additional transformers or voltage conditioning.

Installation and compatibility

The fitting mounts via a hook or bracket to standard pendant or surface fixings; confirm the exact entry thread before ordering. The Moso driver is integrated and non-dimmable. No additional enclosure is required for Zone 1, 2, 21 or 22. Please note delivery is 14 business days.
