Creating a shift schedule from Datetime column

trying to create 3 shift times  fro a column  Create_Date with datetime datatype

2017-05-08 20:57:00.000
2017-05-09 00:44:00.000

day shift 0700 - 1500 hrs
swing shift 1500- 2300 hrs
Night shift 2300 -0700 hrs.

I tried this option using a case statement that seems not to work.
SELECT  Create_Date,
                   CASE
                  WHEN  Create_Date BETWEEN 07:59:00.000 AND 14:59:00.000 THEN 'FIRST SHIFT'
                  WHEN      Create_Date BETWEEN 15:00.000: AND 22:59.00.000 THEN 'SWING SHIFT'
                  ELSE       'NIGHT SHIFT'
                  END ShiftTimes
                  from dbo.FD_Table

I tried converting the column from date time to a varchar 24 format and tried , it only shows Night shift hours

      SELECT
      CONVERT(varchar(50), Create_Date,24),
      CASE
                  WHEN  Create_Date BETWEEN 0700 AND 1459 THEN 'FIRST SHIFT'
                  WHEN      Create_Date BETWEEN 1500 AND 2259 THEN 'SWING SHIFT'
                  ELSE       'NIGHT SHIFT'
                  END ShiftTimes
      from dbo.FD_Table


Sample output
20:57:00      NIGHT SHIFT
00:44:00      NIGHT SHIFT
13:17:00      NIGHT SHIFT
14:53:00      NIGHT SHIFT
14:59:00      NIGHT SHIFT
