LYSFJORD 6403 is an outdoor wall light with a cylindrical die-cast aluminium body, powder-coated in light grey RAL 9006. Safety optical glass closes the cylinder at the top and at the bottom, and a flat bracket holds it off the wall.
How it spreads the light
The luminaire emits in two directions: two 60-degree cones, one up and one down. It therefore draws two diverging bands of light on the wall instead of lighting the surface evenly — the manufacturer intends it for wall surfaces, facades and other architectural schemes.
Two LED modules are built in, with a combined source power of 22.5 W; the whole luminaire draws 26.5 W. The diodes themselves produce 4144 lm and 1814 lm leaves the fitting through the glass — that is the figure to plan lighting with, and it corresponds to an efficacy of 68.5 lm/W. 3000 K is warm white, and a colour rendering index of Ra 80 is enough to judge the colour of render or timber on a facade.
Size and installation
The fitting is 43 cm tall and 15 cm wide, and stands 12 cm off the wall. It weighs 6.73 kg net, so the fixing has to reach the load-bearing layer of the wall rather than the insulation or the render.
The bracket has two ø5 mm holes spaced 73 × 154 mm. The terminals take conductors up to 5 × 2.5 mm² and allow the fitting to be looped through, carrying the supply on to the next one — with a round cable 7 to 10.5 mm across. The luminaire is protection class I, so the circuit has to include an earth conductor.
Resistance and control
IP65 means it is fully dust-tight and resists water jets from any direction, and IK08 means impacts of up to 5 J. A silicone gasket and an EPDM gland keep the housing sealed.
The fitting runs in a DALI2 system with the NightDim function, on 220–240 V. The driver arrives programmed to maximum current; changing the remaining parameters is subject to arrangement with the manufacturer's sales department. The LED modules are not user-replaceable — that is a job for professional service, and the glass is available as a service kit.
