Speedball® LED Lamp This lightweight and portable LED Lamp is a must for any screen printer! Compatible with any photo emulsion*, the Speedball LED Lamp delivers consistent exposure every time and has significantly longer life than traditional 250W photovoltaic alternatives. Its simple on/off rocker switch and smaller size makes it ideal for exposing screens without requiring additional positioning equipment, but the lamp can be easily mounted for those who prefer stationary placement for any design. *Exposure time and distance vary by emulsion type and screen size.
