Transforming LED flashlight into AC power spotlight ?

I wonder why no one have thought of it ?
Its very simple just wiring the + and - of the driver to a female side plug on the side of the flashlight and using a transformer plug-in. Of-course without the battery inside.
Since 4 volts transformer are very rare it would be best to use 5 or 12 volts driver.

It could be a cheap portable spotlight on tail-stand.

i thought about making some spot lights for my truck like this kinda sorta. i have some old halfa lights here and there figured i could mount em somehow on the truck and into a switch. and wire em into the battery. idk seemed like a good idea to me
