The ATEX LED HT-650 Zone 0 Headtorch is the ideal high light output and long duration headtorch for hands free lighting, particularly where access is difficult, requiring climbing or crawling and is CE marked to the ATEX directive and IECEx certified for safe use in Zones 0, 1 and 2 potentially explosive gas and Zones 20, 21 and 22 dust atmospheres.

ATEX LED Zone 0 Headtorch HT-650

Product Information

ZONES: 0, 1, 2, 20, 21 AND 22

The approval code also covers all group II (industrial) gas apparatus groups, for potentially explosive gases up to T4 temperature class, and group I M1 mining applications.

The HT-650 weighs 180 grams including batteries and is constructed from robust, highly durable, high impact thermoplastic materials, which are chemical resistant and fitted with a shatterproof polycarbonate lens. The tilt adjustment mechanism allows the user to angle the light and the bespoke optics deliver a broad spot beam suitable for close up hands free tasks, and is designed for single-handed switching and water/dust tight to a minimum of IP67.

With a ‘fitted for life' high power LED light source, the HT-650 has a powerful light output of up to 130 lumens with an optimum light duration of approximately 17 hours from a set of three AA alkaline cells.  The use of primary cells makes it economical for personal lighting.

The ATEX LED HT-650 Zone 0 Headtorch is supplied fitted with an adjustable removable fabric head band allowing it to be comfortably worn directly on the head for extended periods and a set of 4 helmet clips to allow it to be securely attached to a hardhat. The HT-650 is also supplied with an easy clean inert silicone rubber strap, which grips to a hardhat.
