VMB1DM LED lights

Hi, Am have just installed my first velbus system at home.

I have 2 questions which I have still not managed to sort.

  1. I have 3 VMB1DM dimming modules. One has 4 LED GU10’s connected, two has 8 LED GU10’s connected. All at 240v. The third has 3 LED GU10’s connected. The first 2 are working fine but the third set, one of the LED’s is always on and they will not dim. I have swapped over to another dimmer and they do the same so its not a hardware fault. The first 2 sets are inceptor micro LED’s and the third set are just straight GU10’s in a standard mounting, so guess this has something to do with it. It might be I need another module for this set? (the third set are 3 x 4.5w 240V bulbs)

  2. How do I wire in the push button connection to the vmb1dm? I have a momentary switch that is 3 way. Up down and in the middle off. Can this be used? I assumed pressing up once would turn it on, holding it down would dim and a quick press down would turn off?

Thanks in advance,


I haven’t used that dimming unit, but I have to assume that your understanding of the push button is correct.

Regarding the issue with the mains replacement LED, please have a read of this post I’ve just put up




Yes, now LED lights are so popular all over the world. They are used both indoor and outdoor. LED interior lights are used in offices and other proposes. Now LED lights are used for trucks, buses, cars bikes and others. LED headlights have been favored by mostly those who love the cool white spreads. I also use LED lights for my car. I bought it form JDMastar.
