i've just made a 555 pwm with mosfet controller circuit folow tutorials on youtube.
the controller is work with 12v 10w halogen bulb (it's not work with 12v 50w halogen bulb)but the light bulb seem likes not to be maximum power compared to using light dimmer.

How can i do to make the halogen bulb works right ?

I intend to use a lower voltage bulb like 6v 30w halogen buld or change more powerfull mosfet but i realy dont know if it's work.

 

50W at 12V is 4.1 amps- you need a bigger power supply.

thanks for your reply sensacell

so i need a 12v 4a power supply right ?
and by the way can i use a 4s lipo battery (5500mah 14.8v) to power it ?

 

Yes, 4.16 A Minimum, better to have a 5 A power supply, to not be at max load.

The battery will not last long- maybe 1 hour.

thank you verry much. this's very helpful

 

i've changed to 12v5a power suply but the light is still not bright enough . i tried to change a different capacitor and it's brighter but it's still not bright enough. someone please help me to chose right electric components

 

Post a schematic of your setup (not a link to a tutorial!) and we may have a chance to help.
