OSLON® Square Flat for lighting applications

Compact high-power LED enables tight packing density for clustering. Electrically isolated thermal pad allows for superior heat dissipation designs. Flat package enhances color homogeneity due to reduced color over angle variation. Extremely low thermal resistance helps to maintain the efficiency remarkably high even when driven at higher currents (1.8 A max).
