Safety Tips for Using UV Curing Systems

gallium); fluorescent lamps; and light-emitting diodes (LEDs). The mercury vapor lamp has an output in the short-wave UV range, between 220 and 320 nanometers (nm), and a spike of energy in the long-wave range, at 365 nm. This lamp is a good choice for clear coatings and thin ink layers and produces hard-surface cures and high-gloss finishes.
