The question I would have for you is how do you define "work?" There are really a few aspects at play here, and the answer isn't a simple yes or no.
If you compare LED lights to incandescent lights, there are many differences. First LED lights draw much less power than incandescent lights, and many incandescent dimmers have a problem in that respect. I'd try the VRI06 dimmer first if you have one. They require a 40W load, so how many LED bulbs are you lighting? one or many? It may work depending on the type of LED bulb as well as how many.
If it flickers when low, and/or doesn't dim smoothy when low the next choice is a ELV dimmer. They cost more, but work fine with lights like LEDs, but they are not perfect. This brings me to the second difference between LED lights and incandescent lights; their brightness vs. voltage curves are not the same. If you look at dimmers made just for LED bulbs, like the UPB HAI LV35A001CFL or other LED dimmers, they actually have a lighting curve designed for LED bulbs. So when you set them to 40%, the light output is around 40%. If this precision isn't important to you, and you just want the dimming to be smooth and flicker-free, an ELV dimmer should work good enough, but a LED dimmer is better. BUT I don't think a Vizia RF+ LED dimmer exists yet.
What model of LED bulb are you using? And how many on the circuit? Only these bulbs or incandescent's on the circuit as well?
