Q: Why 0-10V Dimming over regular Mains Dimming?
A: Though a much earlier and simpler signalling system, developed for theatrical lighting, 0-10V Dimming has gone on to become a more popular method of dimming over that of "Mains Dimming". This is because 0-10V dimming follows a more standardised analogue protocol and works by sending a voltage between 0 and 10 volts DC to the user's LED driver; as the voltage is varied the light level thus changes.
With households readily adopting LED strip lighting and still wanting to use wall dimming technology, 0-10V dimming allows for less hassle and stress, where regular mains dimming requires a little more technical knowledge and a lot of testing. Effectively, going for 0-10V dimming eliminates compatibility issues (explained HERE), providing far smoother and lower dimming capabilities over that of mains dimming. To achieve this, an additional length of 'control' cable is needed to be placed between the LED strip controller or wall dimmer and the fitting's driver.
In simple terms, a 0-10V dimmable driver will dim lights down to 0% and turn off at 0 volts, while 10 volts will allow the driver to operate at full intensity of 100%. This is important, because if we look at Mains Dimming, due to it not conforming to a standard protocol, certain dimmer switches may not make the most of the LED strip and driver's capabilities. For example, if a dimmer switch has a starting wattage of 60W, then your strip's ability to lower its brightness will be compromised.
It's therefore important to know whether or not you need mains dimming or 0-10V dimming. Experienced users and installers who are well-versed in using mains dimming hardware will know how to accommodate for this already, but if you are new to this type of dimming, then considering 0-10V dimming is a good option.
