At 19 inches, the beam spread will not be sufficient to illuminate a 17x22 inch print. It will be suitable for a 8x10 inch print. In general, Solux lamps are best suited to track fittings, as you need a distance of about 4ft to get sufficient beam spread. I use three Solux lamps, on a track, with diffusers, to illuminate a 17x22 inch print.
