Philips 806 lm 8W LEDs in the kitchen, they were saying 75mA at 230V

But that 75mA (and the newer 70mA) are clearly bollox, maybe someone
printed the current for 110V lamps on the 230V lamps?

Clearly bollox? depends on what '8W' means,and how much of that
current is in phase with the voltage.

8W = 16VA is not unknown if a capacitor dropper is in play.

I thought they had to meet a decent power factor these days?

Well there is so much inductive load on the grid a little capacitance is
always handy :-)

I dunno what the Law says ... and anyway its worse than that because of
the proliferation of SMPS, most of which only draw power at voltage peaks.



Hot off the Kill-O-Watt

Old finned LED 60W dimmable 100W nondim 40W nondim

VA 19.4 11.1 21.1 8.4
W 16.5 8.8 12.5 5.0
PF 0.85 0.80 0.58 0.60

For some reason, the non-dimmable have worse PF.

The three on the right, are Philips purchased in
the last month.
