LO series Explosion proof Linear Light – ATEX & IECEx Certified,for zone1,2 FAQS

What is an explosion proof linear light?

An explosion proof linear light is a flameproof LED batten built to contain an internal explosion, certified for use where flammable gas or dust is present. The LO series is ATEX and IECEx dual certified (Ex db IIB T6 Gb) for Zone 1, 2 and Zone 21, 22, and is used in refineries, offshore platforms, chemical plants and tunnels.
What is the difference between the LO series and a traditional fluorescent linear light?

The LO series replaces two 18W fluorescent tubes with a single 20W LED module — 20W replaces 2×18W — while lasting over 100,000 hours (L80B20) against roughly 30,000 hours for fluorescent. It delivers 150 lm/W, needs no ballast or starter, and keeps its light output far longer in vibrating industrial environments.
Is the LO series certified for both ATEX and IECEx?

Yes. The LO series holds both certificates: ATEX No. CSANe 25ATEX1229X and IECEx No. IECEx CSA 25.0093X, both for the marking Ex db IIB T6 Gb and Ex tb IIIC T80°C Db. One luminaire therefore covers European ATEX projects and IECEx markets such as the Middle East and Asia-Pacific without redesign.
Which hazardous zones is the LO series certified for?

The LO series is certified for Zone 1 and Zone 2 gas atmospheres and Zone 21 and Zone 22 dust atmospheres, under the markings Ex II 2G Ex db IIB T6 Gb (gas) and Ex II 2D Ex tb IIIC T80°C Db (dust). For how Zone 1 and Zone 2 requirements differ when selecting luminaires, see our Zone 1 vs Zone 2 lighting guide.
What wattages does the LO series offer, and what does it replace?

The LO series is available in 20W, 40W, 60W and 80W. Its 20W version replaces two 18W fluorescent tubes — a 2×18W fitting — cutting energy use by nearly half while producing more usable light, with no ballast losses.
How long does the LO series last?

The LO series is rated L80B20 above 100,000 hours at 25°C, meaning it still delivers at least 80% of its initial light output at that point. Compared with a fluorescent tube replaced every 1–2 years, maintenance intervals are extended several times over — a major saving where access requires scaffolding or shutdown.
Does the LO series support emergency lighting?

Yes, an optional built-in emergency power supply keeps the lamp lit for about 3 hours at 5W when mains power fails — no external kit or rewiring needed. This matters for escape routes and walkways in Zone 1 plants where self-contained emergency lighting is mandatory.
What is the IP rating of the LO series?

The LO series is rated IP67 and IK10, with C4 (ISO 12944) anti-corrosion protection. IP67 keeps out dust and seals the housing against storm-driven rain and high-pressure wash-down, IK10 is the highest impact rating at 20 joules, and C4 (ISO 12944) coating withstands the salt fog and chemical atmospheres typical of offshore and coastal plants.
What cable entries and terminals does the LO series have?

The LO series provides 2 × Φ26 cable entries with one M25×1.5 stainless steel plug (304SS) and one M25×1.5 nickel-plated brass gland, suitable for Φ9–16 mm cable. Terminal capacity is 1.5–4 mm² conductor cross-section.
Where are SEEKINGLED explosion proof lights manufactured?

SEEKINGLED explosion proof lights are designed and manufactured in Shenzhen, China, in an ISO 9001 certified factory that holds ATEX QAN quality assurance notification — meaning the lamps are produced under audited explosion-proof quality control, not traded or re-branded.
What is the delivery time for the LO series explosion proof linear light?

Sample orders take about 5 days. Bulk orders usually take 2 to 4 weeks.
What is the MOQ for the LO series?

Our standard MOQ is 100 pieces. However, during the early stage of cooperation, we can also accept sample orders and small batch orders.
Do you offer door-to-door delivery for explosion proof lights shipped from China?

Yes, we can provide door-to-door shipping. If you don't have experience importing from China, we will work with a reliable logistics company to deliver the goods directly to your warehouse, including export documentation.
Can I become a distributor of SEEKINGLED explosion proof lighting in my country?

If your company is in the oil and gas equipment industry, we would be happy to cooperate with you. SEEKINGLED would be very pleased to become your partner.
