Preparing for a new house with full automation of Velbus modules.
I am thinking of using LED lighting for all fixed light points, but I am a little worried about the low current of these LEDs causing trouble switching and/or dimming them using Velbus modules.
What is the best (or just only working) combination of LED lights and Velbus relays and dimmers?
For dimming, I can think of choosing between:
[ul]
230V Velbus dimmer (VMBDME or VMBDMI?) directly dimming 230V LEDs. I read a lot of minimum load for dimmers to work properly, but cannot find anything of this in the specs of these Velbus dimmers
12V Led trafo to VMB1LED dimmer steering 12V LEDs.
[/ul]
For switching, I can think of choosing between:
[ul]
230V Velbus relay (VMB4RYLD) directly switching 230V LEDs. Can there be a problem with current leaks because of the low demand of LED lamps (typical 4-8 W/LED)
12V Led trafo to VMB4RYLD or VMB4RYNO switching 12V LEDs.
[/ul]
I have a lot of led lights, most 230v working well with vmb4ry units. I have one led strip light also working via a 12v transformer which is turned on using a vmb4ry change. If i get additional 12v led strip lights I may get a permanent 12v supply and switch the 12v via vmb4ry channels instead of using the channel to turn on the 230v to the transfomrer
I have only one dimmer in the house and this is dimming 7x gu10 halogens but am looking tonswitchbthrse to dimmable led gu10 replacements. My understanding is this may or may not work depending on bulb manufacturer. I have some units on order ton try and see if they work. My understanding is though that if you are starting off a new install, try to avoid dimming of 230v leds as it is difficult. I’m no expert on lighting so perhaps vellmen or other posters could confirm this. I think my longer term plan will be to try and move to a 12v dimming setup!
Switching is not a problem, dimming is.
90% of all led bulbs are not dimmable, even if the manufacturer claims they are dimmable.
Some work with leading edge dimmers, some require trailing edge dimmers.
In most cases, the dimming range is rather small. Very low intensities are usually not possible.
In some cases, the bulbs flicker, turn off, get defective, have a very short lifespan and/or destroy the dimmer.
Basically, check what type of dimmer is required for your type of bulb, get a bulb and try, the only way to know if it will work.
12V PWM dimming is in my opinion a better solution.
