The LED Advantage

The company’s UV LEDs will replace toxic and short-lived mercury vapor lamps across all UV wavelengths and catalyze a host of new applications. In contrast to mercury vapor lamps, LEDs are robust, compact, and non-toxic. With AuroraUV technology, UV LEDs have the potential to use 50% of the electricity required by mercury vapor lamps and will have a usable lifetime of ten times as long, resulting in a life cycle cost savings of two to four times. Furthermore, there will not be the hazardous waste disposal that is inherent in mercury lamps, resulting in a less polluted environment.

More Advantages

There are additional applications for UV LEDs that can not be satisfied by mercury vapor lamp technology. These include: Military non-line of sight covert communication and detection of certain environmental hazards.

Mercury lamps have sever other negative attributes that LEDs do not have:
They produce a large amount of heat, are temperature sensitive especially to cold temperatures, may fluctuate in intensity, require a warm-up time after turning on, and have a reduced lifetime due to on/off cycling. In UV curing for example, using UV LEDs results in a reduction in heat output, a constant intensity, and quick turn on time, all of which translate into a more uniform light emitted in the UV range produced at a lower cost.
