Surface-mounted light fixture IKU

LEDcylindricalIP65

Iku is a family of surface-mounted luminaires designed for architectural outdoor lighting in weather-exposed environments such as bus terminals, cantilever roofs and passageways. The cylindrical, neutral form and multiple light distributions provide flexibility for renovation projects and new installations.

Special features

• Tunable white (dynamic colour temperature control)
• >120 lm/W (high luminous efficacy, depending on configuration)
• Safety class II
• Protection rating IP65 — dustproof and protected against water jets
• Corrosion-resistant aluminium housing with No‑Rinse surface treatment
• Surface-mounted installation with option for through-wiring
• Precise aiming: rotation ±10° on the mounting plate
• Designed service life: target ≈75,000 operating hours (eco-design objective ~20 years)

Sizes

• Size 3 — Diameter: 128 mm; Luminaire flux: 529–1,334 lm; Indicative connected load: 6.9 W – 11.3 W
• Size 5 — Diameter: 192 mm; Luminaire flux: 1,198–4,625 lm; Indicative connected load: 18.9 W – 34.3 W

Light distributions

• Wallwash (asymmetrical lens wallwashers) — uniform vertical illumination of façades
• Oval flood — axially symmetrical, linear lighting for corridors and covered routes
• Wide flood — rotationally symmetrical for general ambient lighting
• Extra wide flood — very wide beam for broad area coverage

Applications & lighting concepts

• Suitable for exterior architectural lighting, façades, covered passageways, bus and transport terminals
• Supports combined indoor-outdoor concepts and AAA lighting approaches (Architecture, Activity, Atmosphere)
• Selectable distributions enable wallwashing, linear corridor lighting and general ambient illumination
