running a 12v bulb with an arduino

-

hi im running simple code use ghostbusters proton pack make lights flash , such gun light flashes when press button im using normal leds powered 4 x 1.5v aa batteries want change flashing light brighter


specification
base: g9
64 x light emitting diodes
led type: 3014 smd
lighting color: warm white
color temperature: 3000k
power: 3w
voltage: ac 220v 240v
luminous flux: 250 lm
dimension: 5.1 x 1.5 cm

is case of changing power supply 12v , upping resistors on other leds arduino able power , control it?

quote
power: 3w
voltage: ac 220v 240v


there leds made automotive use work @ 12v.  run led(s) 12v, use fets or transistors manage current (called "drivers"), , use arduino on-board power regulator step-down 12v 5v.
