With variable brightness up to a blazing 11,000 lux, strong enough to shine through 300# paper and fabric, the LightPadÂ« PRO adds a color temperature adjustment to bring projects into their natural color from a warm to cool white. Changing color temp highlights different tonal qualities in your artwork. Designed for easy use with a T-square, the LightPadÂ« PRO features a tempered glass cutting surface. The UV-free light is safe for the eyes, and no-fade safe for archival photos and documents. Capacitive touch controls save settings from use to use. Long-life LEDs never need to be changed. The comfortably curved edge is ergonomically friendly, while the smooth bottom makes the LightPadÂ« PRO a pleasure to use on your lap or worktable. The new LightPadÂ« PRO is proudly made in the USA by Artograph.
