What switch to use for a stroboscopic light

Using Arduino General Electronics
1

Hi,

My first arduino project has been a stroboscopic fountain with a old speaker and some stroboscopic led controlled with my arduino board (MEGA 2560) it works fine but the lighting is really weak.
I have 7 tiny white LEDs (~3V) in parallel on a breadboard and I have to make some compromise on the duty cycle, at 60% there's ok light but the droplets of my fountain are blurry, or I go down to 30%, I can barely see my fountain but the droplets are crisp and the effect is really cool.

So what I wanted was to have a big LED on an electric outlet but using a switch that I can control with arduino to have the same control on strobing frequency and duty cycle as with my little LEDs.
What would be the name or type of switch to use for this ? I don't know much about electronics yet.

Also if you think I can get much more lighting just from the power supply of my arduino board and some tiny LEDs, that would be cool, I wouldn't have to deal with high voltage.

Thanks in advance.

The magic word is "logic level MosFet transitor".

Have a google of using a transistor as a switch as a way to increase load and voltage capability.

You can only put leds with their series resistors as a parallel

Thanks, so I need a mosfet and an LED strip. do I need to "damage" the LED strip (cutting the power supply cable) to insert the mosfet or there are product that already include a mosfet or where a mosfet can be inserted ?

I´m confused

Your big LED on a mains outlet already has a built-in power supply for the LEDs. It cannot be rapidly turned on and off.

Ok but would it work on a LED strip ?

After you told me the name mosfet, I search on youtube and I found a demo of a LED Strips controlled via a Mosfet so I guess I will use that.

I have 40vdc LEDs that are bright and hot enough to char paper.putting a controlled relay between the power supply and the LED would let you do the strobe. Not sure how long the LED or relay will last.
