The invention relates to a light emitting device comprising at least one light source and at least one ceramic spherical color converter material, which helps to ease the manufacture as well as to improve the luminescence properties of the light emitting device. The device preferably includes a housing having a housing pass-through, a penetrator device securely and sealably positioned so that the penetrator device passes through the housing pass-through, and a vacuum system comprising a vacuum source securely and sealably attached through the housing for advancing a patient’s tissue onto the penetrator device. Ordered sets of phrases of known length are then formed from the codewords. These probabilities are used to compute the LLRs. In this manner, the chemical additive becomes bonded to the cellulose material alleviating problems associated with retention.
