I was bored and was playing with one of the plug in monitors which measure the amount of power your fridge or freezer uses over a set time.
I just wanted something handy to plug in and the desk light was handy. Then I looked at the power factor 0.87 and my thoughts are should not that have been corrected in the lamp.
It's an 11W Ikea lamp which actually shows as drawing 8W screw fitting E27 so nothing handy I can replace it with to see if just an odd bulb or is there is generally no correction with CFL.
A 0.2 μF capacitor would not cost much and I would have expected it to have been fitted in the bulb not having to be added external.
I know with standard florescent tubes we add the power factor correction in the fitting but with a E27 it could have standard bulb or LED as well as CFL so seems odd.
Maybe it was fitted and it has blown. In the main all my table lamps are now LED and either SES or BA22d so nothing to swap it with to test.
