My old light bulbs stopped working, so I bought 2 fluorescent U shape light bulbs as a replacement:
The recommended power in the light fixture is 34W per unit but they only have 32W in stock. After installing the new lights, everything looks good and is brighter than before. However, I notice some pulsing coming from the lights, almost like a tremor. The light is solid white but somehow it's pulsing.
The lights have been on for at least 8 hours by now. Does anyone know what could be the cause of this issue? The old lights work fine no problem until they burnt out.
