The CL-TF1000 is a great companion for productions on the move. Used as a key or background light it's just the right size.Insertion of the bulb is as easy as opening the front lid of the fresnel and inserting the G22 1000w Tungsten bulb into the socket. Care should be taken when handling the bulb to not touch it with bare hands. Use a cloth or soft tissue when handling or inserting it. Finger oils and smudges will weaken the quartz of an HMI or Tungsten bulb and shorten its life.
