Fibaro FGB-002 Dimmer Bypass 2, Black

If you have been trying to fit a Smart dimmer in a house with no third (neutral) wire in the wall where the dimmer goes, you’ll have found that there’s only a few Smart dimmers on the market that work with two wires. The reason for this is that with two wires if they turn the lights off they lose power themselves and stop being Smart. So some manufacturers get around this by making dimmers that never go entirely off. Now the amount of current that flows when they are ‘off’ of tiny and shouldn’t make the bulbs glow. But guess what? With LED bulbs it can. So what you do Is you stick this in the ceiling rose of the light, wired in parallel with them (so literally you have one end in the connector for one wire and the other in the connector for the other wire), and it increases the resistance so that when the Smart dimmer goes ‘off’ the tiny current is not enough to make the bulbs glow. So if you have light fixtures with multiple bulbs and don’t want to install expensive Smart bulbs in each socket (I’d need ten for the two chandeliers in my living room), and have two wires in the wall, these are life savers.

If you need to fix ghosting (LED lights stay slightly on) when you fit a smart dimmer, then this does the job perfectly. My living room has 14 5W LED downlights, and had a standard rotary dimmer. The downlights were fitted years ago by a previous owner, and are builders merchant cheap no-name ones which also flickered badly when dimmed. I wanted to add smart control, to integrate with my Hue bridge and other lights. Replacing all the fittings with fire rated GU10 cans and smart bulbs, or even just normal LED bulbs would cost way too much. No neutral wire at the light switch, as usual for older UK fittings. So I fitted a candeo zigbee rotary no-neutral trailing-edge dimmer switch (which looks identical to the old dimmer, so happy wife), which works fine for switch/voice/app control. However, as it still draws a little power to run the switch itself when lights are off, the only route to neutral is through the LED lights - and that means that when the switch is off, that small draw is enough to light an LED or two faintly. Better LED downlights might not have this problem, but that means replacing all the fittings and bulbs, which I'm trying to avoid. I tried a different dimmer bypass (which didn't work) but this fibaro bypass works perfectly, I just wired in parallel at the first downlight. As a bonus it also stabilises the downlights better at low power, so I was able to set the dimmer minimum level two clicks lower while still allowing all the LEDs to turn back on fully with no flicker. A few hundred pounds for 14 downlight cans and bulbs to have smart lights without ghosting, or pay an electrician to run a neutral to my dimmer switch via a tricky duct; or this £10 bypass in the ceiling inside the junction box. I know which I'm happier with! Obviously, enough knowledge (and a detector pen) to do basic DIY with mains electric wiring safely is required, and only install when the breaker is off; or get an electrician.

Module obligatoire si vous utilisez le Fibaro FGD-212 avec un cablage sans neutre (ie. en complément d'un va-et-vient) avec des ampoules LED (dimmable ou non). Vous pouvez le mettre sur n'importe quelle ampoule du même point lumineux peu importe. Résultat : plus de scintillement et extinction réelle de toutes les ampoules ou spots LED. Bref je recommande

Fantastic solution. I use a MODE Evolution trailing edge dimmer and was getting ghosting (faint glow) when dimmed to zero (turned off) as the bulb remains an electrical path for dimmer circuits. Also know as a minimum load capacitor (MLC) this will eliminate ghosting and flickering with LED bulbs. Simply connect across the bulb Live and Neutral either in the ceiling rose or at the dimmer end. Good price as Lutron sell an MLC that is 50% more expensive but does the same job. Will work with all dimmer controllers.
