Thanks for your advice.

I have LightBox (software) installed on my Tablet, long time ago.
LightBox comes from "Google Play"

Setting:
Select White color
Color Temp/White Balance slide - half (not maximum)
Brightness slide - maximum

Shall I set "Color Temp/White Balance slide" to maximum ?  Or try another color?  There are 7 colors for selection, Red/Blue/Yellow/White/Light Blue/Pink/Green.

I have a LED light pad, purchased long time ago.  Pls refer to attached screenshot.

I never use it.  The light is very poor compared to my Tablet.

Regards
