When choosing the best light source for your UV curing application, there are a lot of factors to consider, ranging from compatibility with adhesives and coatings, to speed, light uniformity, versatility, cost and more.
UV Arc Lamp Advantages
An arc, or electrode lamp, is the most common of all UV light sources; UV light is produced when mercury vapor passes between an electric arc. Arc lamps typically provide between 500 and 2,000 hours of lamp life, which is significantly lower than a UV LED alternative. However, depending on the object being cured, an arc lamp may be advantageous to employ, due to several factors, including lower cost, speedy curing, versatility and compatibility.
UV LED Advantages
UV light emitting diodes (LEDs) are semiconductor components that produce light when electrical current flows through them. With a life expectancy of over 20,000 hours, UV LEDs are growing in popularity, but not all UV LED curing suppliers or solutions are created equally.
Our LED curing systems use cool-output, long-life UV LEDs in multiple spectral types for high-intensity, rapid curing. They are ideal for applications that are sensitive to heat or designed to work with a narrow spectral range.
