Jelight Company, Inc. of Irvine, CA has acquired a United States Patent for their JFC-412 series of Portable Ultraviolet Floor Curing Equipment.

Curious about the UV floor curing process? Here is our newest demo video to show you how it all works.

We have just released our newest portable UV floor curing unit, the JFC-417L.  The JFC-417L provides a cure width ranging from 17-21"-- great for use on larger area UV floor cure jobs in the wood and VCT industries! 


Features of Double-Bore Lamps

What are the features?

The specialized design of this mercury bulb eliminates dangling lead wires because of their location at only one end of the lamp. This feature is ideal for such applications as dipping into liquid or inserting the lamp into small apertures. The Double-Bore have strong isolated spectral lines that are well separated from the others. The bulbs are free from contaminats which are harmful to the operation of the lamp. We take extra, unique steps in the manufacturing process to ensure that each lamp is free of contamination. This process improves the quality, stability, uniformity and lifetime of the lamps. When operated properly, these are extremely stable. This is important for accurate calibration and instrumentation applications where the lamp stability is vital. In comparison to other UV light sources, the Double-Bore lamps are very cool burning. The temperature rarely exceeds 100° C. This is important where the components or substances must not be heated by the light source used. The Double-Bore mercury bulbs are long lasting uv light sources. Under optimal conditions lifetime is 5000 hours, although they have been operated for as many as 30000 continuous hours. All of the Double-Bore bulbs can be filled with a variety of rare gases such as argon, krypton, neon, xenon, and helium.
