Product Information
The Wolflite H-4DCA primary cell powered safety lantern is one of the latest versions of the highly successful, industry standard range of Wolflite Ex lanterns, from The Wolf Safety Lamp Company.
Approved by BASEEFA, the Wolflite H-4DCA has been ‘CE' marked in compliance with the 94/9/EC ‘Explosive Atmospheres' (ATEX) Directive, for use in a wide range of potentially explosive gases, vapours, mists and dusts. Conformance to the ATEX directive will reassure the user that the H-4DCA lantern has been designed
and approved to the very latest editions and interpretations of the relevant European standards, that it
complies with all ‘essential safety requirements', and has been designed with due regard to state-of-the-art technology. ATEX Directive Approval also ensures continuity of supply beyond the year 2003.
Additionally the H-4DCA lantern has both a Lloyd's and an MCA type approval for use in explosive atmospheres in marine applications.
The lamp is constructed from a new, exceptionally robust and highly durable thermoplastic material, well able to withstand the effects of heavy industrial use. In addition to this, the material is anti-static, preventing the build up of potentially dangerous electrostatic charges. A 1.2" thick, toughened, scratch resistant glass lens with rubber seal, together with a second seal fitted at the lens ring and lamp body joint, ensure that the lamp is protected from ingress of dusts and liquids and can therefore be used in the dustiest and wettest conditions possible.
The outstanding light output from this relatively small and compact lantern is achieved with the use of a high output, high efficiency halogen bulb, rated at 4.8V 0.5A, focused within a 4" diameter parabolic reflector. This provides the user with an extremely well defined beam of intense white colour.
The H-4DCA lantern has been approved for use with alkaline or zinc primary cells. The use of alkaline cells is recommended because of their significantly greater capacity, delivering a brighter white light for up to 20 hours duration from one set of cells; by comparison, nearly four times the duration of zinc D cells. The H-4DCA is supplied complete with a convenient removable shoulder strap.
