Maximize LED brightness using PWM or Something else

Other Hardware LEDs and Multiplexing

Hi,

Can the maximum brightness and light output of a LED be increased using PWM with an Arduino, especially if there are a number of them in parallel?

Are there any other solutions to increase output from LEDs?

Thanks for any help

No, PWM is used t make the LEDs dimmer.
The only way to get them brighter is to put more current through them.
Do not connect LEDs in parallel without each having its own resistor.
