The special geometry of the lens ensures a uniformly illuminated light opening with high visual comfort.
The special light distribution of the double wallwashers efficiently illuminates the opposite walls of corridors. The diffuse, reflected light from the walls also illuminates the floor and ceiling.
Tunable white technology
Just as the colour temperature outdoors changes continuously during the day, the colour temperature of indirect lighting can be adjusted indoors to e.g. support lighting concepts for Human Centric Lighting.
Covered or flush mounting detail
Recessed downlights have covered mounting rings. Flush mounting rings are available as accessories. Size 2 recessed downlights are optionally available in a covered or flush version.
Wide luminaire spacing with wallwashing
Efficient ERCO photometrics allow certain luminaires to be spaced unusually far apart at up to 1.5 times the distance to wall.
Five sizes and five light distributions enable perfect, economical lighting for applications of all dimensions: in large public buildings, offices and conference centres, but also in smaller rooms in the restaurant and hotel sector. Iku enables large luminaire spacing with wide light distributions thanks to oval light beams. Iku wallwashers and double wallwashers enhance rooms and corridors with visual width and increase the impression of brightness. Iku is characterised by high luminous efficacy and a long service life. The combination of tunable white, different light distributions and modern connectivity creates lighting in the sense of Human Centric Lighting.
Iku in the application
Individualise Iku for your use case
With our “ERCO individual” service we offer you extensive options for the individualisation of series products as well as support in the development of sophisticated special luminaires. In order to match Iku even more efficiently to your project requirements, further variants are available on request in addition to the series configuration. These include, for example:
Anti-glare cone: gold matt, silver matt, champagne matt or copper matt-coated and other colours
Connection: 3- or 5-pole plug with connection cable (Wago or Wieland)
Mounting ring: 10,000 further colours
Do you have further requirements with the product?
Please contact the consultant team in the following ERCO office:
Wide beam, rotationally symmetrical light distribution for general lighting.
3W - 36.9W
419lm - 6453lm
For uniform general lighting with high visual comfort, the luminaire spacing (d) between two Iku downlights may be up to 1.5 times the height (h) of the luminaire above the working plane (rough guide).
Arrangement: d = 1.5 x h
The wall offset should be half the luminaire spacing.
Arrangement: a = d / 2
Linear general lighting for spatial structuring and the illumination of zones and pathways.
Axially symmetrical light distribution for illumination of parallel walls in corridors and hallways.
16.1W - 24.3W
1533lm - 3232lm
For the uniform vertical lighting of opposite walls, the distance to the wall (a) on both sides with Iku double wallwashers should be around one third of the room height (h). The luminaires should always be positioned on the central axis between the walls.
Arrangement: a = 1/3 x h
Application area: Corridors, e.g. in administrative and healthcare buildings
For good longitudinal uniformity, the luminaire spacing (d) of Iku wallwashers may be up to 1.3 times the distance to the wall (a).
Arrangement: d ≤ 1.3 x a
Optimal wall distances and luminaire spacing values for individual products are specified in the wallwasher tables.
