A method for forming a light emitting device includes providing a light emitting diode (LED) configured to emit light of a first color and providing a plurality of semi-spherical lenses made of a silicone material that contains no phosphor material. Each of the lenses has a layer of phosphor material attached thereto. The method also includes testing the plurality of lenses to select a subset of lenses that converts light of the first color to light of a second color. The method further includes forming the light emitting device using the LED, one of the selected subset of lenses, and a heat conductive substrate. In an embodiment, after the testing of the plurality of lenses, one of the selected subset of lenses is disposed overlying the LED. In another embodiment, the testing of the plurality of lenses is conducted with a light source other than the LED.
