12V LED Explosion Proof String Light: Industrial-Grade Hazardous Location Safety

What does “explosion‑proof” mean for a light fixture?

Explosion‑proof fixtures are designed to contain any sparks or ignition sources within the housing so they cannot ignite gases or vapors outside the light. They are capable of withstanding an internal explosion and venting gases safely without causing an external ignition.

What is the difference between Class I Division 1 and Division 2?

Class I covers locations where flammable gases or vapors may be present. Division 1 means those gases or vapors are likely present during normal operations, whereas Division 2 indicates they exist only under abnormal conditions, such as equipment failure or accidental release.

How do explosion‑proof lights differ from intrinsically safe devices?

Intrinsically safe equipment limits the electrical and thermal energy so it cannot spark or get hot enough to ignite a hazardous atmosphere. Explosion‑proof fixtures can use higher power and brighter output, but they rely on robust housings and flame paths to contain any internal ignition.

How many lamps are included per string, and can strings be linked?

Worksite Lighting offers these string lights in 5‑lamp, 8‑lamp and 10‑lamp configurations. Each string is designed with male and female receptacles so multiple strings can be connected end‑to‑end to cover larger work areas.

How bright is each lamp and what kind of lamp is used?

Each lighthead uses a durable LED that delivers up to roughly 1 500 lumens of daylight‑balanced illumination. LEDs provide long service life (around 50 000 hours) and generate less heat than incandescent bulbs.

What certifications and ratings do these string lights carry?

The lights are certified for Class I Division 1 & 2 (Groups C & D) and Class II Division 1 (Groups F & G). They also carry UL 844, UL 1598, CSA C22.2 and NFPA 70 certifications, and the housings are NEMA 4X rated for rain‑tight and corrosion‑resistant performance.

Are these lights suitable for dusty or fibrous environments?

Yes. The lights meet Class II Division 1 requirements for combustible dusts and Class III requirements for ignitable fibers or flyings, making them suitable for grain handling, mining and other dusty industrial settings.

What design features make these lights durable for industrial use?

They feature copper‑free aluminum housings with an epoxy powder‑coat finish, rubber bumpers to absorb impacts, a heavy‑duty SOOW cord resistant to oil and water, and full swivel hooks for flexible mounting.

In what industries or sites are explosion‑proof string lights commonly used?

These lights are used in oil and gas facilities, petrochemical plants, refineries, shipyards, mines, marine environments and other hazardous areas where flammable gases, vapors or dusts are present.

Do the 12‑volt versions include a built‑in transformer?

Yes. The 12 V models have an integrated step‑down transformer that converts standard 120 V power to 12 V at the source. This lowers the voltage on the cable and lamps, improving safety in confined spaces. Versions with 24 V output are also available to suit different site requirements.
