Basic components required for efficient exposre using a 1KW MERCURY or METAL HALIDE lamp used by professional printing companies. Low price, often less than $300, allows the artist, hobbyist, or professional to burn screens, expose lithographic plates, cure resins and adhesives, and perform many other applications using long-wave UV.


Two sources of Ultraviolet available that require no additional hardware. Lamps are internally ballasted and incorporate an efficient internal reflector. Available in 300 and 160 Watts with medium standard socket or large mogul industrial screw-in base. Excellent for portable applications. Also widely used for solar simulation in compliance with U.S. standards certification.

Available in long-wave UV-A or medium-wave UV-B.


Ultraviolet fluorescent lamps are available in all sizes of UV-A, UV-B and UV-C in standard linear, compact, HO-highoutput, and VHO-very high output in most sizes. Custom sizes and wattages made to specification.
