What kind of inductive load does a mains LED lamp present?
LEDs are a nonlinear load and probably these lamps will not have a power factor correction converter. This means that the current will not be sinusoidal therefore you will have some reactive power flowing. There may be a PFC choke before the rectifier bridge. 

If you want to measure the power factor and harmonic content just take a scope with voltage and current probes and measure line voltage and line current. 

PS. This it how you distinguish China Export mark from European CE:
