A light emitter package having increased feature sizes for improved luminous flux and efficacy. An emitter chip is disposed on a submount with a lens that covers the emitter chip. In some cases, the ratio of the width of the light emitter chip to the width of said lens in a given direction is 0.5 or greater. Increased feature sizes allow the package to emit light more efficiently. Some packages include submounts having dimensions greater than 3.5 mm square used in conjunction with larger emitter chips. Materials having higher thermal conductivities are used to fabricate the submounts, providing the package with better thermal management.
