Rugged, high-efficiency linear lighting for Zone 1/21 and Class I, Division 2 hazardous locations
The Rhino Series is a heavy-duty explosion proof LED linear luminaire built for the demanding conditions of oil and gas, petrochemical, marine and process industries. A corrosion-free GRP body, impact-resistant PC cover and IP66 protection keep it performing in wet, dusty, vapour-laden and high-temperature areas, while up to 130 lm/W efficacy cuts energy use compared with conventional fluorescent fittings.
Key Highlights
Product Overview
Designed as a direct, long-life replacement for explosion proof fluorescent fittings, the Rhino Series combines high-quality SMT LEDs with a Meanwell driver for stable, flicker-free output across a wide AC100–277V input range, with a DC supply option also available. It is offered in two lengths: the compact RL2 (10–40 W) and the longer RL4 (20–60 W).
Each fitting can be specified with an integrated emergency battery that maintains 1,200 lm for up to 180 minutes during a power failure, making it suitable for escape routes and critical process areas. Dimmable and non-dimmable drivers, clear or frosted covers, and LED plate or LED tube light sources allow the luminaire to be matched to each project.
Key Features
- Certified for hazardous areas: ATEX, IECEx and UL844 Class I, Division 2 marked for gas and dust atmospheres.

- Flexible power supply: AC100–277V 50/60Hz as standard, with DC supply available.
- GRP body and PC cover: lightweight, non-corroding housing with a high-impact polycarbonate diffuser.
- Heavy-duty construction: high impact resistance for harsh industrial and offshore use.
- Premium components: high-quality SMT LEDs and Meanwell LED driver.
- Fully sealed: waterproof, vapour-proof, dust-proof and corrosion resistant to IP66.
- Configurable: dimmable or non-dimmable, clear or frosted cover, LED plate or LED tube source.
