I plan to control neon flex, max length 28 meter. It is LED based light source with 220V power changed to 24V DC. I just asked the producer about the amper it can have on such a length. Soon I am back.

Thanks for the hints anyway.

If you go "future" and will dimm LED lights, then use a PWM dimmer

    What kind of load do you need? The Krida you linked to one has
    2A per channel.

    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 voltage
    work required.
