The Wolflite H-4DCA primary cellpowered safety handlamp is one of the latest versions of the highly successful, industry standard range of Wolflite Ex handlamps, from The Wolf Safety Lamp Company. Approved by BASEEFA, the WolfliteH-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 directivewill reassure the user that the H-4DCA handlamp has beendesigned and approved to the verylatest editions and interpretations ofthe 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 alsoensures continuity of supply beyond the year 2003. Additionally the H-4DCA handlamphas both a Lloyd’s and an MCA type approval for use in explosiveatmospheres in marine applications.The lamp is constructed from anew, exceptionally robust andhighly durable thermoplasticmaterial, well able to withstand the effects of heavy industrial use. In addition to this, the material isanti-static, preventing the build upof potentially dangerous electro-static charges. A 6mm thick,toughened, scratch resistant glass lens with rubber seal, together witha second seal fitted at the lens ringand lamp body joint, ensure that the lamp is protected from ingressof dusts and liquids and can therefore be used in the dustiest and wettest conditions possible. The outstanding light output fromthis relatively small and compacthandlamp is achieved with the use of a high output, high efficiency halogen bulb, rated at 4.8V 0.5A,focused within a 100mm diameterparabolic reflector. This provides theuser with an extremely well defined beam of intense white colour. The H-4DCA handlamp has beenapproved for use with alkaline manganese, zinc chloride or zinc carbon primary cells. The use of alkaline manganese 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.
