Product Overview

A surface-mounted LED downlight designed for quick installation without ceiling drilling or structural modification. The die-casting aluminum housing provides stable thermal management and long-term reliability. Available in 10W to 40W models with a compact footprint from φ90mm to φ195mm, it fits residential and commercial interiors. Uses CREE COB LED chips with high efficacy of 95 lm/W and a power factor above 0.9. Offers multiple dimming options including non-dim, triac, DALI, and 0-10V. Optical design minimizes glare, and the unit is rated IP20 or IP65 depending on the model. Certified to CE, RoHS, FCC, SAA, and PSE. Suitable for dry and wet locations with operating temperature range from -20°C to +40°C.
