Recently replaced some light fittings in my mums house - a hall light and landing light. The landing light has 2 way switching (can be turned on/off from both upstairs and downstairs). She told me that the upstairs landing light is flickering on and off so I went to take a look. Firstly, I checked all wires in the light fitting and in the wall switches - all okay. The lights are fancy things with 5 branches on them and are fitted with 5 cool white g9 leds (same as the downstairs one - exactly the same fitting). I have removed each bulb one by one and still the same. What I did notice after some investigating was that if I turned the upstairs landing light on initially from downstairs, it comes on fine and can be turned on and off okay from the upstairs switch too but if I turn if off from downstairs and turn it on from the upstairs switch, all led bulbs flicker and struggle to come on then after 20-30 seconds it might come on then go back off after a short while. It's just baffling me how it's okay if controlled from the downstairs switch initially.
