Dimming correction values for Philips Master LED spot 4W GU10

[Gast]

Hello

Does anyone have the dimming correction values for Philips Master LED spot 4W GU10? And can tell me which dimming option is best?

I'm finding that dimming these are (without correction value) best with the "Trailing edge dimming for incandescent lamps, HV holegens, ..." option. Which is weird I think. I would go for one of the "Mains-LEDs" options but I'm not getting any light unless I give 50%+ power.

Maybe I should go for "Mains-LEDs" option but with the appropriate correction values? Does anyone have these?

Thanks !

dimmable led gu10s usually work best with trailing edge dimmers, so im not surprised that works best.

most mains dimmable gu10s wont do much until around 35-50%, and you usually see a wider range of control if you turn off the visual perception correction - with it you will need around 50% to get any light, with it off you should see light from around 25-35% depending on the number of bulbs on the circuit

Thanks for the info!

I do see a difference in speed of dimming depending on the number of bulbs on the circuit.
For example: a circuit with 14 bulbs dim very good. A circuit with only one bulb: very very slow and unresponsive. Not sure how to find a solution for the one or two bulb circuits.

some people suggest adding one of the dummy loads - basically a big resistor with a heat sink to load up the dimmer and help it trigger - but what a waste of energy!

is an example

What a waste of energy indeed.

With turning off the visual perception correction, you mean no correction in the input voltage 1 and display value 1 fields of the dimmer settings? I'm not seeing any other correction option. Thx!

in the parameters is a tick box

Strange, I don't have that checkbox! I have that dropdown box with dimming options instead.

im using dmx dimmers, so maybe that option isnt available if you are using the loxone dimmers
