Pura 89570 - Replacement UVC Light Bulb

Guaranteed Replacement Ultraviolet (UV) Bulb - 4 pin single end - 21 Watts - 17.17 Inch Length Lamp - Worry-Free Performance for 1 Year  Our Pura 89570 UV Light Bulb For Germicidal Water Treatment is a 21Watts UV bulb that gives you a worry-free performance for an entire year. The 17.17-inch lamp has four-pin on a single end and is made using ceramic. The lamp has a life of 10,000 hours after which we recommend that you replace the light bulb even if it continues to emit light. Since the light bulbs are intended to destroy microorganisms it is necessary to schedule the replacement of the bulbs annually to ensure the system's efficiency. These high-quality lamps have a peak UV output of 254nm that help in reacting with the genetics of microorganisms such as spores, virus, bacteria, and other pathogens. This bulb is available with a shatterproof coating that in case of damage keeps the lamp glass from falling into the unit where is installed. This results in an easy way to dispose of glass if it shatters. You can select this shatterproof option above. Do I need shatterproof coating? Although shatterproof coating can lower the intensity of the UV-C bulb by as much as 15%, it is recommended for applications in which it is crucial to avoid potential glass breakage at all costs. These applications include but are not limited to food processing and medical institutions. However, if glass breakage would be inconvenient but not catastrophic, skipping the costly shatterproof coating is quite alright. After all, we do not use shatterproof coating with our glasses and plates at home. The UV lamp starts instantly and makes use of a coil filament that operates hot. The UV lamp is managed by the life of electrodes and works well for the following applications that require UVC intensity: Well water Drinking water Surface water Municipal water Wastewater Foodservice/processing Beverage service/processing Hospitals Aquaculture Pools, Spas, and Water Features Chemicals Oil, Gas, and Power Pulp, paper, and wood Electronics Cosmetics Pharmaceuticals Hotels Water bottlers Laboratories Marine and more Technical Specifications: Total Length: 17.17 inches (436mm) Arc Length: 13.78 inches (350mm) Lamp Quartz Diameter: 15mm Lamp Voltage: 67V Lamp Wattage: 25 Watts Output UVC Watts: 7.3 Watts Output uW/cm^2 @ 1m: 72 Peak UV Output: 253.7nm Glass Type: Non Ozone Base Style: 4 pin on a single end Base Material: Ceramic Rated Life: Up to 10,000 hours Spectral Output of Germicidal UVC Light Bulbs  Drawing of Replacement UVC Bulb Item # 510415 *Hg - Lamp contains mercury - manage in accordance with your local disposal laws by visiting: www.lamprecycle.org *All germicidal UVC light bulbs listed are compatible brand UV products.
