A method for making a lighting apparatus includes providing a substrate and disposing a light-emitting diode overlying the substrate. The light-emitting diode has a top surface oriented away from the substrate and a plurality of side surfaces. A light-conversion material is provided that includes a substantially transparent base material and a wave-shifting material dispersed in the base material. The concentration of the wave-shifting material can be at least 30%. In an embodiment, the concentration of the wave-shifting material can be approximately 50% or 70%. A predetermined amount of the light-conversion material is deposited on the top surface of the light-emitting diode while the side surfaces are maintained substantially free of the light-conversion material.
