- The mineral plates within the lamp heads have an estimated working life of 1000 hours. This means that they should last for years if used once a day for 20-minute treatments. If and when you need to replace your TDP lamp head, all you've got to do is:
- Make sure the lamp is off (switches and dials at the "off" position) and unplug the power cable from the wall.
- Unplug the power cable leading from the lamp to the head.
- Turn the knob on top of the neck connector to loosen.
- Pull the head out and replace with the new one.
