public class RotateLight : MonoBehaviour {

    float startTime = 0f;

    // Update is called once per frame
    void Update () {
        Quaternion startRotation = Quaternion.Euler (50f, 30f, 0f);
        Quaternion endRotation = startRotation * Quaternion.Euler (0f, 180f, 0f);

        directionalLight.transform.rotation = Quaternion.Slerp (startRotation, endRotation, startTime / 10f);
        startTime += Time.deltaTime;
