Power Factor Correction

SLIPSHOD & SLAPDASH · Sep 3, 2015

Is there a correction for LED lamps, either GU10 or panels.

Cant find any manufacturers data or online details.

I should have said no definitive answers on line. I am trying to complete a loadings calc for a shop with 100% led lights

As far as I am aware they have no start up current.

I've never seen any figures for gear losses etc. Just go with the lamp wattages , can't be far out surely ?

do you have a good clamp meter to test the installed lights?

LED lamps have SMPSU's, so they have stupid inrush currents, but, for very short periods, so I ignore it, as it is "the same" as motor starting currents, and can be ignored under, "most", circumstances.

There are no "gear losses" ala dishcarge lights.

Note, there are exceptions, as there are on all rules, and this one is empirical, rather than theoretical.
