buzzing led problem , thinking of using lower watt bulbs

[selondonman]

i put in a ring of 12 leds in a room (too many in reality)

put in a good dimmer meant to be able take load but lights causing horrible buzz

i am currently using 5w bulbs

if i replace the bulbs for 3w should that reduce the load and stop the buzzing, trying this before having to take lights out of the ceiling and all the work

thanks

Ever since I had an issue with buzzing and flickering I now only fit Varilight V Pro dimmers for LED downlights. Not had any problems since but the clients often have issues with the cost (£45+).

if i had 12 leds on a 10 maximum dimmer, if i took the bulbs out of two sockets, would the dimmer think there was 10 bulbs working ? does anyone know of any blanking plates / covers that can go on top of or in the empty downlighter ?

Reducing the load will not help.
Get some decent downlights.
As mentioned above, LAP is not the way to success.

true lap crap but had 120 bulbs to buy ... any suggestions on a good value brand

yes 2 way silent trailing edge 250w dimmers led .. varilight v pro .. lights wills dim not to full off and dimming increases the buzzing if that means anything

What happens in the different modes for the varilight v pro? The TLC LED’s only dim 30% in the default mode and they need mode 3 to dim to maximum available whereas Phillips dimmable GU10 dim fully in the default mode which surprised me. It may solve the buzz as well although that may be the bulbs.
Also, we are talking about GU10 not MR16 bulbs?

12 is too many on a V Pro dimmer switch it will fail eventually. I know from experience. The maximum recommended by Varilight is 10 bulbs even though that is less than the 120W rating. I spoke to Varilight and they explained that they recommend only 10 x GU10 LED's max due to inrush when they are first switched on. You need to fit a V Com dimmer switch that can handle up to 20 x GU10 LED's rated at 180W. TLC sell them if you have one near you?
