Product Information

HT-400Z0
ZONES: 0, 1, 2, 20, 21 AND 22

The HT-400Z0 is compact and lightweight weighing only 90 grams including batteries and constructed from robust, highly durable, high impact thermoplastic materials which are chemical resistant, and is 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 IP66.

With a ‘fitted for life' high power LED light source, the HT-400Z0 has up to 75 lumens of light output, with an optimum light duration of approximately 8.5 hours from a set of three AAA alkaline cells.  The use of primary cells makes it economical for personal lighting.

The ATEX LED HT-400Z0 Headtorch is supplied fitted with an adjustable removable fabric head band allowing it to be comfortably worn, at a low profile, directly on the head for extended periods and a set of 4 helmet clips to allow it to be securely attached to a hardhat.
