The ATEX LED HT-650 Zone 0 Headtorch is designed to provide high light output and long duration hands-free illumination, making it especially suitable for challenging environments where access may be difficult, such as climbing or crawling. It is CE marked to the ATEX directive and IECEx certified for safe use in potentially explosive atmospheres, including Zones 0, 1, and 2 for gases, and Zones 21 and 22 for dust. This certification ensures compliance with rigorous safety standards for hazardous environments.
This headtorch’s approval extends to all Group II industrial gas apparatus groups, covering potentially explosive gases up to the T4 temperature class, and it is also approved for Group I M1 mining applications, highlighting its versatility for use in both industrial and mining settings. The HT-650 weighs just 180 grams with batteries included, making it lightweight yet robust. Its construction uses highly durable, impact-resistant thermoplastic materials that resist chemical damage. The lens is made from shatterproof polycarbonate, offering added protection against impacts and harsh conditions. A tilt adjustment mechanism allows the user to angle the light beam, while the bespoke optics provide a broad spot beam that is ideal for close-up, hands-free tasks. Designed for ease of use, the torch features a single-handed switch and is sealed to at least an IP67 rating, ensuring protection against dust ingress and water immersion.
Powered by a ‘fitted for life’ high power LED light source, the HT-650 delivers an impressive light output of up to 130 lumens. Its light duration is optimized to approximately 17 hours using a set of three AA alkaline primary cells, offering an economical and reliable power source for extended personal lighting needs. The use of primary cells makes battery replacement straightforward and cost-effective.
For comfortable and secure wear, the ATEX LED HT-650 Zone 0 Headtorch comes equipped with an adjustable, removable fabric headband designed for direct use on the head over extended periods. Additionally, it includes four helmet clips that allow the torch to be firmly attached to a hardhat. To enhance helmet mounting, an easy-clean inert silicone rubber strap is also supplied, providing strong grip and stability on hardhat surfaces.
The HT-650 offers numerous practical features including compliance with the ATEX Directive and IECEx Scheme certifications, making it safe for use in explosive gas, vapor, mist, and dust atmospheres within the designated zones. It operates effectively within the T4/T3 temperature classes and an ambient temperature range of -20°C to +40°C. Its enclosure is crafted from high impact, chemical-resistant thermoplastic material, paired with a shatterproof polycarbonate lens. The beam emitted is a broad spot combined with a wide-angle fringe light, designed to illuminate close working areas with clarity and efficiency.
Certified under Baseefa 10ATEX0067X and IECEx BAS 10.0023X, the HT-650 is intrinsically safe (‘ia’ protection) for Zones 0, 1, and 2 gas groups IIA, IIB, and IIC, as well as dust Zones 21 and 22, dust group IIIB, with a maximum surface temperature rating of 155°C. This headtorch is an excellent choice for professionals working in hazardous environments who require reliable, ergonomic, and high-performance hands-free lighting solutions.
