If you go "future" and will dimm LED lights, then use a PWM dimmer like this one: http://www.digitallighting.com/animationfolder/PWM%20Dimmer%20repeater.htm Found this informative video about incandescent vs. LED dimming https://www.youtube.com/watch?v=fWh2obSY0dQ On 2017년 09월 19일 00:07, Max

What kind of load do you need? The Krida you linked to one has 2A per channel. http://www.inmojo.com/store/krida-electronics/item/8-channel-ac-light-dimmer-module-arduino/ If you need more, this one has 4A per channel, but you need two of it to reach 7 channels. More expensive, but no high
