About this product

Circle is On Light's adjustable LED surface-mount cylinder accent, offered as the Circle R with a Ø4" (100 mm) round body and the Circle S with a 5-1/8" (130 mm) square body, both installing over a standard octagonal junction box (Circle R with a 5" round adapter plate). The die-cast aluminum head swivels 90° and adjusts through 180° for precise aiming. Delivered output is specified at 625 lm (9 W), 1200 lm (11 W), 1800 lm (15 W), or 2000 lm (15 W) — nominal at 3500K/84 CRI, with custom outputs available on request — at a nominal efficacy up to 90 lm/W. LEDs are offered in 2700K, 3000K, 3500K, and 4000K at 80, 90, or 97 CRI, plus Bread, Meat, and Fish food-optimized options, in 15° spot, 25° narrow flood, 38° flood, and 60° wide flood beam spreads. Housings ship in RAL 9016 white, RAL 9005 black, or custom finishes, with a roughed textured powder coat and an optional adapter plate that can be finished differently from the cylinder. Dimming is TRIAC line-voltage (standard) or 0–10V (5%) and DALI with a remote driver, on 120V Class 2 input (15 W). Rated for dry and damp locations at IP20 (wet-location use voids the warranty), with LM80-tested L80/B10 lumen maintenance of 50,000 hours at 25°C. Certified to US and Canadian safety standards, assembled in Beloeil, Canada, and backed by a five-year warranty on the LED light engine, driver, and all fixture components.
