Full description
* Security of effective disinfection over the useful lifetime of the lamp.
* High system efficacy because it is not required to over-design the purification system to maintain effectiveness of disinfection.
* Good environmental choice because of lowest amount of mercury.

* Short-wave UV radiation with a peak at 253.7 nm (UVC) for disinfection purposes.
* Protective inside coating ensures almost constant UV output over the complete lifetime of the lamp.
* Special lamp glass filters out the 185 nm ozone-forming radiation.
* Warning sign on lamp indicates that the lamp radiates UVC.

* Deactivation of bacteria, viruses and other micro-organisms.
* Residential drinking water units.
* Fish pond water units.
* In-duct air treatment units.
* Stand alone air purifiers.

Warnings and Safety
* A lamp breaking is extremely unlikely to have any impact on your health. If a lamp breaks, ventilate the room for 30 minutes and remove the parts, preferably with gloves. Put them in a sealed plastic bag and take it to your local waste facilities for recycling. Do not use a vacuum cleaner.

DANGER: Risk Group 3 Ultra Violet product. These lamps emit high-power UV radiation that can cause severe injury to skin and eyes. Avoid eye and skin exposure to unshielded product. Use only in an enclosed environment which shields users from the radiation.

A wide variety of micro-organisms in the water can cause disease, especially for young and senior people, who may have weaker immune systems. UV light provides purification without the addition of chemicals that can produce harmful by-products and add unpleasant taste to water. Additional benefits include easy installation, low maintenance and minimal space requirements. UV has the ability to inactivate bacteria, viruses and protozoa. Each type of organism requires a specific dose for inactivation. Viruses require higher doses than bacteria and protozoa. Understanding the organisms to be neutralised will help to determine to size of the UV system that will be required. For example, to kill 99,9% of E.coli, a UV dose of 90 J/m2 or 9 mW.sec/cm2 is required. UV installations are suitable for industrial, municipal and residential markets. The quality of the water has an important effect on the performance of UV systems.The common factors that have to be considered are iron, hardness, the total concentration of suspended solids and the UV transmittance. Various organic and inorganic compounds can absorb UV. When there is uncertainty about what may be present in the water, the UV transmittance should be tested. Most drinking water supplies have UV transmittances between 85% and 95%.

Separate treatment technologies often are required to improve the water quality before purification:
* Sediment filters, to remove particles that "shadow" microbes or absorb UV.
* Carbon filters, which remove organic compounds and undesirable odors.
* Water softeners to reduce hardness.

UV is often used in conjunction with Reverse Osmosis(RO) applications. Purification prior to the RO systems increases the durability of the RO membrane by reducing the accumulation of bacterial biofilms. The reactor of a UV purification device must be designed to ensure that all microbes receive sufficient exposure of the UV.

Factors, that should be considered, when, choosing the right size of UV equipment, in order, to achieve the desired purification objectives are peak flow rate, the required dose and the UV transmittance of the water.
