Zusammenfassung:	Aspects of the present disclosure relate to a lighting device that is configured to provide light with a high color rendering index (CRI) value and/or uniform planar illumination. The lighting device may include a circuit board, a light emitting diode (LED) mounted to the circuit board and configured to emit broad spectrum light having a first CRI value, a photo-luminescent material disposed above the LED mounted to the circuit board configured to increase the CRI of the broad spectrum light emitted by the LED from the first CRI value to a higher, second CRI value, and an elastomer encapsulating at least part of the circuit board. Additionally, the lighting device may include a lens disposed over the LED configured to increase the maximum emission angle of light from the LED and a diffuser disposed above the lens and configured to diffuse the broad spectrum light.
