I was looking for an LED light for movie shooting, and I found a cheap item of 252 yen at Amazon.
This is a mini LED light that plugs into the earphone jack of the smartphone and is used for auxiliary lighting.
The 16 LED lights glowed brightly when the switch was turned on.I am lucky.
The main body is light and bright. Adjustment is high, medium, low. It is quite good.
So, I processed it soon.
I will make a hole in the iPhone case made 100 yen modified by me.
Insert the LED light jack into the hole.
