light box on an ipad

What iPad model do you have?

Light tables/boxes only work using a dedicated plug-in power supply, using a rechargeable lithium battery that can charge over USB or USB from a computer and/or a powered USB hub.

There are no light table boxes that work with iOS devices and Lightning cable power.

Light tables/boxes draw too much power from an iOS device.

Why not simply take a picture of a sketch/drawing, using the camera on your iPad , bring it into a drawing app on your iPad, then use use any type of common capacitive stylus or battery powered, so-called “active”, fine point capacitive stylus or smart Bluetooth stylus to trace over the photo/image in drawing app?

This is one of the strengths of using an iPad.

Why not just purchase a dedicated light box/table/panel?

There are lots of thin light box panels to choose from on Amazon.

Do not have to have any iPad involved, at all!

What is there to know?

They are just portable thin slabs that have bright LED or LCD lights in them to use for arts and crafts projects.

They come in different sizes and prices.

Prices range from $60 to $120 depending on the size on the light panel

You use these on another flat surface or on a drawing table/kitchen table/desk.

Look up light boxes/light panels on Amazon.

Huion and Litup are two companies that make portable light boxes

You can even use a strong above light sources, like newer LED office lamps or mountable/clamping LED lamps if the light from these LED lamps are bright enough from above for drawing and tracing if the paper is translucent/transparent enough.

Large/long enough and bright enough LED office style desk lights can run the price gamut from $50 to $100, or so, too!

What’s the problem?

I have given you some very good options to look into.

You would need to print out images from the Internet to trace manually.

You know that, right?
