The Speedball UV Exposure Lamp uses 30W LEDs to expose your prepared silk screen to ultraviolet light as part of the photo emulsion screen printing process. It also mimics sunlight for cyanotype printing. The lamp includes a 180 degree swivel bracket that can be mounted to a surface for hands free use, and an on/off switch. It is lightweight, portable and easy to use with broad coverage. Includes an exposure time chart (7 - 12 minutes).
