Round track light IKU

polymercommercialdimmable

Iku is a round track downlight by ERCO designed for flexible, efficient general lighting from electrified track systems. Its rounded housing integrates two lens optics directing light vertically downwards and contains the control gear, enabling high visual comfort and easy reconfiguration of ambient lighting.

Key features

• >120 lm/W (product family benchmark); typical product configurations achieve up to approx. 114 lm/W
• Casambi Bluetooth connectivity available; also supports DALI or luminaire-integrated dimming
• UGR < 19 for high visual comfort
• Anti-glare cone and division of the illuminated area into two light outlets for a pleasant impression of brightness
• Interchangeable lenses (quick replacement and freely rotatable within the housing) to change light distributions
• Service life target: at least 20 years (≈75,000 operating hours)

Light distributions and optics

• Round beam options for efficient general lighting: Wide flood (approx. 70°) and Extra wide flood (approx. 80°)
• Oval distribution for linear illumination: Oval flood (approx. 20° x 60°), rotatable to align direction
• Three selectable light distributions in the product family (round wide, extra wide; oval)

Typical sizes and performance

• Construction / diameter: 280 mm
• Luminous flux (luminaire): 1,784 – 2,818 lm (product family range shown on page)
• Connected load: approx. 21.9 W – 22.3 W (depending on configuration)

Applications & integration

• Designed for flexible ambient lighting from track systems — combines advantages of recessed luminaires and movable spotlights
• Particularly suited to interiors where furniture layout or architectural use may change; lenses can be swapped to adapt beam shape and orientation
