Portable LED Light Panel

LightPanel is an App that turns your mobile device into a flexible multi-purpose LED light panel - one that you always have with you to provide fill light for macro or product photography.

  • Both brightness and colour temperature are modifiable.

  • Colour temperature can be varied between 1,500K and 15,000K.

  • New with version 1.1, LightPanel can display arbitrary colours for creative lighting effects.

LightPanel can also be used as a lightbox or light table, for scanning slides & negatives or tracing artwork.

  • A grid can be displayed to aid alignment on the light table.

  • The grid can be resized and moved around.

LightPanel is available as a universal purchase for iPad, iPhone & iPod Touch running iOS 12 or later and Macs running MacOS 10.15 (Catalina) or later.

The Mac version can be controlled with the TouchBar, menus & keyboard shortcuts in addition to the interface of the iOS version.

Keyboard shortcuts also work in LightPanel 1.3 on iPads running iOS 13 with a hardware keyboard attached.

LED Panel

In this picture I'm using LightPanel as a fill light for a product photo.

I've set the light temperature to match the rest of my indoor lighting.


Here I'm using LightPanel to scan a slide with my camera.

I've adjusted the grid to match the size of a slide to make it easier to keep subsequent slides in the exactly the same position.

LightPanel can display arbitrary colours, rather than using the selected colour temperature:

  • Tap the Hue button to quickly switch between Colour Temperature and Hue colours.

  • Drag along the slider to change Hue.

  • Drag up & down away from the slider to adjust Saturation.

  • Drag parallel to the slider to adjust Brightness.

Known Limitations

  • LightPanel only controls the brightness of the primary display in a multi-monitor setup. Given LightPanel is intended to be used on a mobile device, this is unlikely to be an issue in practice.

LightPanel doesn't access or store personal or device information of any kind.
