Product Remarks

Bestseller! Square DL/4 is a 4” square LED downlight. Precise reflector design minimizes aperture brightness, virtually eliminates the inter-reflections inherent with square apertures and provides a shielding angle of 45°. 

Luminaire is powered by one of a number of Xicato 19mm XTM LED modules, all of which are distinguished by extraordinary color consistency (within 2-step MacAdam ellipse).

Luminaire achieves efficacies up to 72 lumens per watt.
