Alrouf Ex Proof B-series Highbay

What are explosion-proof lights?

Explosion-proof lights are fixtures specifically engineered and certified so they cannot ignite flammable gases, vapors, or combustible dust in the surrounding air. The B-Series is certified to ATEX (112 G Ex mb eb IIC T4 Gb), IECEx (Ex mb eb IIC T4 Gb), and UL844 (Class I Division 2, Groups A-D; Class II Division 1, Groups E-G) standards, with an IP66-rated sealed aluminum housing and tempered glass lens.

Where is explosion-proof lighting required?

Explosion-proof lighting is required anywhere flammable gases, vapors, or combustible dust may be present — including oil and gas production, refining, loading and storage facilities, LNG plants, chemical production and storage sites, paint facilities, mining operations, metal smelting and foundries, offshore and marine platforms, aerospace clean rooms, military facilities, flour and food/alcohol production plants, and power generation stations. As a general rule, any area with high humidity, high dust, high vapor, or high temperature where a flammable atmosphere could form needs this protection.

What type of lights are best for a high bay shop?

For hazardous industrial shops such as refineries, chemical plants, or mills, a certified explosion-proof LED high bay is the right choice — not a standard LED high bay. The B-Series is available in four housing sizes covering 20W to 400W, so the shop's size and ceiling height determine the right model. Dimmable or non-dimmable driver options, along with a choice of 40° or 60° beam angle, allow the coverage and intensity to be tuned to the space.

How many lumens do I need for high bay lighting?

Lumen output scales with wattage: 20W → 2,800 lm, 40W → 5,600 lm, 60W → 8,400 lm, 100W → 14,000 lm, 150W → 21,000 lm, 200W → 28,000 lm, 300W → 42,000 lm, 400W → 56,000 lm. This works out to roughly 140 lm/W efficacy, with 80 CRI and a color temperature range from 2200K to 7000K.

Are LED high bay lights better?

Yes — modern LED high bays like the B-Series combine high-quality SMT LEDs with a Meanwell driver, and feature a replaceable LED board and driver so the whole fixture doesn't need replacing if a component fails. They're backed by up to a 5-year limited warranty, housed in lightweight but heavy-duty aircraft-grade aluminum, rated for -40°C to +55°C operation, and finished with marine-rated powder coating for corrosion resistance.

What are the common problems with high bay lights, and how are they solved?

Driver or LED failure requiring full fixture replacement is solved with a replaceable LED board and driver design. Overheating in enclosed or hot environments is addressed with an aircraft aluminum housing for heat dissipation, rated up to +55°C ambient. Corrosion in humid, marine, or chemical air is prevented with marine-rated powder coating and stainless steel hardware. Power interruptions in critical areas are covered by an integrated junction box with optional emergency battery backup of up to 3 hours. Water and dust ingress is prevented with an IP66 rating and tempered glass lens.

What is the best high bay light for hazardous areas?

For hazardous, high-risk industrial sites, the right choice comes down to certification, durability, and flexibility. The B-Series covers this with multi-standard certification (ATEX, IECEx, UL844, ABS marine, SASO, TÜV), a full wattage range from 20W to 400W within one product family, a 5-year warranty, and emergency battery backup — making it a purpose-built answer for these environments rather than a generic high bay light.
