    dimmable GU10 LEDs

    Does anyone have recommendations? I've tried the Screwfix LAP 5w ones, they are ok but don't dim right down. Is this the same with others such as Sylvania? cheers

I want to use 10w square LEDs which require 10-12v DC and 1050mA each. I am aware that most of the outputs are 12v from the PSU. Does this...

    I have a customer who has several stand alone Lutron dimmers, some just masters, some masters and slaves. These dimmers are dimming ELV MR16 spot lights. He has a total of around 30 of these spots and they were fitted around 2009. This is the Lutron dimmers he has...

    Leds and capacitance...

    There are always quite a few threads where the problem is the LED staying on slightly even when switched off and I see that the solution is to fit certain resistors as a snubber. I have never had this problem. I guess I have either been lucky or have found a combination of switches/lamps that...

    LEDs & Interference

    I'm led to believe that LEDs (as in the actual basic semiconductor device themselves) are comparatively strong emitters of radio frequency interference. Don't know about how much power or where in the spectrum but that's what I was once taught. Just wondering whether anyone has seen this as a...

    Simple Question about LEDS and Resistors

    First off, I want to say that I'm not an electrician and don't know much about electricity. My question... Is it ok to have two resistors connected to a 3mm led? Please don't ask why two resistors. I just want to know if it would harm the led or have any kind of negative effect on the circuit...
