4 Pin Step Base on a Single End - 40 Watt Germicidal Water Treatment Bulb

The Sterilight R-Can SSM-39 Generic Replacement bulb is a four-pin step base on a single-end light bulb. The UVC light bulb has a total length of 33.19 inches and an arc length of 29.92 inches. The 40 Watt germicidal light bulb from CureUV has a peak output of 253.7nm. 

The quality of drinking water affects our well-being and the germicidal light is proven to destroy viruses, bacteria, protozoa, molds, and other harmful pathogens. The lamp features a wavelength with lethal effectiveness of  253.7nm that helps disrupt harmful microorganisms' DNA and renders them harmless. Measuring 33.19 inches in length, the UVC lamp has a long-lasting life rate of 10,000 hours, you get a 12-month worry-free water sanitizing operation. After that time the light may still be visible but the germ-destroying ability of the compatible UV light bulb may have been reduced so we recommend you replace the lamp bulb.

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 Sterilight R-Can SSM-39.

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.
