This is a Workhorse Lumitron Exposure Unit, approximately 8 years old and in very good condition. Built for a screen printing shop, it accommodates screens up to 20” × 24”, and features a vacuum lid for tight screen contact and a digital timer for consistent exposures, ensuring sharp, accurate stencils. Despite its age, it has been well maintained and performs just as it should, with strong suction and even light distribution. A durable, professional-grade unit that’s ready to keep up with daily shop use.
