Viqua SHO740/4C-RL UV Light Bulb for Germicidal Water Treatment

4 Pin Stepped on a Single End - 80 Watt Germicidal Water Treatment Bulb

The Viqua SHO740/4C-RL UVC Light Bulb has a 4-pin stepped on a single end - 80-watt germicidal water treatment bulb. The germicidal light bulb features a wavelength with a lethal effectiveness of up to 254nm that helps disrupt the DNA of harmful microorganisms and renders them harmless. You get a 12-month worry-free water sanitizing operation after which the light may still be visible but the germ-destroying ability of the light bulb may have reduced.

We offer two versions of this UV-C bulb; a good quality foreign-made generic replacement unit and an ultra-high quality US-made unit. Both lights are guaranteed to be 100% compatible with the Viqua SHO740/4C-RL

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:
