BLOW O435WL-L10GF3K is an outdoor wall lamp with a compact, half-round aluminium body in graphite. Light leaves it in two directions — upwards and downwards — through round glass lenses set in polished rings. The source is a built-in LED module, so the fitting lights up as soon as it is wired in.
Size and mounting
The body is 11 cm wide and 6.8 cm tall, and it projects 10 cm from the wall — that last figure is the one to compare with the width of the cladding board or fence post it is going on. It weighs 0.71 kg.
The manufacturer's instruction sheet shows the lamp going onto a plate screwed to the wall, with the body locked to it by a hex screw. The conductors run to a terminal block inside the housing, so a supply cable has to reach the mounting point. Protection class I means the installation must carry an earth conductor.
How much light it gives
The LED module draws 10 W and delivers 900 lm, roughly what an old 60 W bulb used to give — except that this fitting sends that output two ways, up and down the wall. The 122° beam angle spreads the light wide, so the wall gets two broadly opened cones rather than narrow stripes.
3000 K is warm white with a slightly yellow cast, close to the light of a traditional bulb. A colour rendering index of Ra 80 is enough for a path and a facade, though it does not hold colours as faithfully as an Ra 90 source. The manufacturer states 50,000 hours of service life; the source is permanently built in and cannot be replaced, and the fitting is not dimmable.
Where it can be used
IP54 protection covers dust and splashing water from any direction, so the lamp suits an open facade with no roof over it. The manufacturer gives an operating range of −40 to +50 °C, which lets it stay on the wall through the winter.
The catalogue assigns it to hotel and restaurant facades as well as fences and balconies — anywhere light is meant to spread along a vertical surface. The form is modern and free of ornament: a smooth graphite body whose only visible detail is the ring around the glass. The Blow series also includes a 5 W version, O435WL-L5GF3K, for repeating several fittings along one wall.
