Specifications of H-4DCA

• Svhc: No SVHC (18-Jun-2010)

The Wolflite H-4DCA primary cell
powered 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 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 handlamp 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 handlamp
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 electro-
static charges. A 6mm 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
handlamp is achieved with the use
of a high output, high efficiency
halogen bulb, rated at 4.8V 0.5A,
focused within a 100mm diameter
parabolic reflector. This provides the
user with an extremely well defined
beam of intense white colour.

The H-4DCA handlamp has been
approved 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.
