What to check if LED bulb could not be switched on?

In order to ascertain whether or not you have received a faulty bulb please first check if:

  1. The bulb is receiving power from a switch/dimmer.
  2. The bulb is securely in the fitting.
  3. Try the bulb in an alternative fitting on the same circuit.
