  • Collimator legs are inserted into the side holes, and then LEDs are attached with mounting thermal adhesive.
  1. At the edge of the disk drill a hole with a diameter of 3.3 mm and make a thread in it. This hole is needed to install the capacitors.
  2. The grid is removed from the pepperpot, the protective ring is put aside.
