A moulding of ceramic fibre material is press-fitted around the ends of the lamps and a thermal limiter is provided to limit the operating temperature of the apparatus. Each lamp is provided with a reflective coating along the lower part thereof, so as to reflect upwardly infra-red radiation emitted in a downward direction.
