Explosion Proof Linear LED FAQs

What’s the difference between Class 1 Division 1 and Class 1 Division 2?

Class 1 Division 1 areas have ignitable gases or vapors present during normal operation or frequently, so fixtures must be rated to contain ignition. Class 1 Division 2 areas handle flammable gases or vapors but they are normally confined and only present under abnormal conditions such as leaks or equipment failures. For Class 1 Division 1 applications, models like IR4 and EXI are recommended. For Class 1 Division 2, models such as IR3, IR7, and IR1 are suitable depending on the lumen and output requirements. The EXH model is primarily used for dust (Class 2 Division 1) but also covers Class 1 Division 2.

Do these support pendant, surface, or chain mounts?

Yes, all models including EXI, IR1, IR3, IR4, IR7, and EXH support common mounting methods. The IR1 fixture is most often surface-mounted in wet or marine locations. The IR7 model is well suited for chain or surface mounting, making it popular in process bays, while the IR3 includes swivel brackets that allow precise aiming. Always confirm clearance and conduit routing based on your site requirements.

Are marine or wet environments supported?

Yes, several models are designed to operate in marine and wet environments. The IR1 is specifically built for wet and outdoor marine applications with a non-metallic, corrosion-resistant fiberglass housing and gasketted sealing. The IR3 is marine-rated (UL 1598A) and includes additional corrosion protection. The EXI and EXH models also offer enclosures and finishes that are suitable for wet or corrosive conditions. For highly demanding environments, it is always recommended to confirm salt-fog and corrosion requirements with your MAES representative.

Can you provide photometrics and submittals?

Absolutely. Each model section includes a Download Spec Sheet link. Request IES files and project submittals via the Request a Quote form, we’ll deliver photometrics based on your mounting heights, spacing, and target foot‑candles.

What about warranty and lifespan?

These lines are engineered for long service life in harsh conditions. Standard warranties are typically 5 years with L70 lifetimes designed to minimize relamping downtime. Check each datasheet’s exact warranty or ratings.
