LED (Light Emitting Diode) lighting has been widely used as a major light source to illuminate photographic prints. But it is not clear how aggressive LED lighting affects to image stability of prints. The light stability tests were carried out using some commercially available white LED lamps and fading behavior was compared to the standardized xenon light testing which simulates indirect sunlight indoor. It was clarified that fading under LED lighting is less than xenon lighting but it correlates well to the xenon testing in the order of prints in light stability.
