Супертонкая cветодиодная световая панель Reflecta 10317, Черная

The reflecta light pad A4 Super Slim has a viewing area sized 310 x 210 mm, so that 24 mounted 35mm slides can be viewed at the same time. The LED lamps provide consistent illumination of the viewing area, which means that also the border areas can be used for viewing transparencies.

The sleek design is creditable - this light pad integrates very well in a modern working environment due to its very low thickness.
