Have tried numerous trailing arm dimmers as recommended, but all of them make the lights flicker at any level below full brightness, and buzz like a bee. Would personally buy individually transformed lights that are dimmable. These lights have three light levels that are switchable before installation, and have tried to dim with different dimmers, but still flicker at lower light levels on each setting.Without dimming function, these are very good light fittings at reasonable price.

Der Schieber für die Licht Wahl fällt raus ...und die Zuleitung ist auch lose.... ansonsten ganz ok ......

Ottimi faretti dal punto di vista della luce e che si può scegliere la scala di calore del faretto da luce calda a naturale a fredda.Come faretto è tutta plastica difetto le molle un po scadenti

Produkt gefällt mir sehr beim Dimmen leuchtet einer von den drei schwächer

Very nice, bright lights, and work well with a trailing-edge dimmer. The switch-able wavelength is a nice feature, but remember to set them all the same before fitting. Not like me.Installed 6 in my bedroom ceiling, and when its quiet I do notice a very slight buzz from the units themselves. In a noisier environment you probably wouldn't notice this.
