Alternative to noisy relays?

Hello,
I am using an Arduino to control some 220v lights with relays. The relays make some very noisy clicks and i’m trying to get rid of that. Are all relays noisy? I’ve also read somewhere that transistors may be an alternative to relays, so could that be an option?
Thanks in advance.

You can use solid state relays - these are a semiconductor device (not a transistor - those are only suitable for switching dc) for switching AC.

There should only be one click when a relay picks and one click when the relay drops.

DrAzzy: You can use solid state relays - these are a semiconductor device (not a transistor - those are only suitable for switching dc) for switching AC.

Thanks, i'll get one of these and see how they react.

Indeed, but i'm trying to reproduce a storm with thunders, so it will change it's state quite often.

Ah yes, that good old-fashioned "On a dark and stormy night...clickity clack go the wheels on the track"

Seriously though, like DrAzzy said an SSR is going to be totally silent.

"Indeed, but i'm trying to reproduce a storm with thunders, so it will change it's state quite often."

You can hear the relay click in 'storm with thunders' ? ;)

Yes use a SSR.
