Bay 51 Series Explosion Proof Linear Light | ATEX & IECEx Certified for Zone 1, 2 FAQS

What is an explosion proof pendant light?

An explosion proof pendant light is a flameproof luminaire suspended from the ceiling to illuminate work areas inside hazardous locations. The Bay 51 series is ATEX and IECEx certified (Ex db eb mb IIC) for Zone 1, 2 and Zone 21, 22, commonly hung over pumps, workshops and walkways in refineries, offshore platforms and chemical plants.
What does "Ex db eb mb" mean on the Bay 51?

Ex db eb mb combines three protection types in one luminaire: Ex d (flameproof), Ex e (increased safety) and Ex m (encapsulation). It is this triple protection design that lets the Bay 51 reach IIC — the most severe gas group, which includes hydrogen — and obtain Zone 1 certification.
Is the Bay 51 rated for IIC gas groups?

Yes. The Bay 51 carries the IIC gas group rating — the most stringent classification, covering hydrogen and acetylene atmospheres — in its marking Ex db eb mb IIC T6/T5 Gb. Many competing linear fittings are only IIB rated, so IIC removes the risk of under-specifying the luminaire for your plant.
Which zones is the Bay 51 certified for?

The Bay 51 is certified for Zone 1 and Zone 2 gas atmospheres and Zone 21 and 22 dust atmospheres, under Ex II 2G Ex db eb mb IIC T6/T5 Gb and Ex II 2D Ex tb IIIC T80°C/T95°C Db, with identical IECEx certification.
What wattages does the Bay 51 offer?

The Bay 51 offers seven power steps from 18W to 60W (18/20/30/36/40/50/60W). Its 20W version replaces two 18W fluorescent tubes, so most legacy installations convert one-for-one with a single LED luminaire.
Does the Bay 51 have an amber light option?

Yes. A 590nm amber LED version is available as an option. Amber light contains no UV wavelength, is friendly to marine life, and meets the special requirements of semiconductor manufacturing plants.
Does the Bay 51 support emergency lighting?

Yes. An optional built-in Ni-Cd emergency power supply keeps the lamp lit for about 3 hours at 5W (1,000 lm) when mains power fails — self-contained inside the fitting, with no external emergency kit or rewiring required.
What is the IP rating of the Bay 51?

The Bay 51 is rated IP67 and IK10, with C4 (ISO 12944) anti-corrosion protection — dust-tight, jet-wash and driving-rain resistant, 20-joule impact resistant, and coated for salt-fog and chemical atmospheres on offshore and marine installations.
How long does the Bay 51 last?

The Bay 51 is rated L80B20 above 100,000 hours at 25°C, retaining at least 80% of initial output at that lifetime — several times the service interval of the fluorescent fittings it replaces.
Which standards does the Bay 51 comply with?

The Bay 51 is designed to IEC 60079-0 (general), 60079-1 (flameproof "d"), 60079-7 (increased safety "e") and 60079-18 (encapsulation "m") — the full standard set behind its Ex db eb mb IIC marking, certified by both ATEX and IECEx.
Where are SEEKINGLED explosion proof lights manufactured?

SEEKINGLED lights are designed and manufactured in Shenzhen, China, in an ISO 9001 certified factory holding ATEX QAN quality assurance notification — audited production, not trading or re-branding.
What is the delivery time for the Bay 51?

Sample orders take about 5 days. Bulk orders usually take 2 to 3 weeks.
What is the MOQ for the Bay 51, and do you offer door-to-door delivery?

Our standard MOQ is 100 pieces, with samples and small batches accepted during early cooperation. We also provide door-to-door shipping — if you have no importing experience, we handle the logistics and deliver directly to your warehouse.
Can I become a distributor of SEEKINGLED explosion proof lighting in my country?
