Ultraviolet UV Lamps for Germ Guardians

Experienced GermGuardian UV Lamp buyers can skip the introductory text by scrolling down to look for their replacement part number (yellow highlighted, example: LB4000).

When the GermGuardian line was introduced, the air sterilizers and subsequently the air purifiers were well received by big box retailers.

Lowes, Home Depot, Bed Bath & Beyond, Walmart, Target, and Best Buy displayed the GermGuardians.

But once the glitter wears off, these vendors always switch the low-end consumer to the next "new" product, and do not support their sale with parts or filters.

Buying online is then the only option until the manufacturer eventually stops support of older products.

Guardian products are notorious for short UV lamp life.

This type of bulb, even those of higher quality, rarely emit UV-C for more than 12 months continuous use, emissions of the germicidal wavelength fall faster than those of visible light.

Guardian Technologies suggests UV bulb replacement at 4,000 hours, about five and a half months, when the average lamp's UV emission will have weakened by maybe 15%.

At a maximum of 5000 hours (7 months), now making about 50% of full UV-C strength, the light may flicker or change colors, which is when many users decide on replacement.

So vendors advertising "replacement every 6-8 months" are stretching the envelope, as most of these lamps are barely making UV-C after six.

And the most common consumer complaint is about the lamp no longer being effective against odors after much shorter run times than expected.

Fluorescent lamps produce UV-C by running electric current through low-pressure mercury gas.

New mercury-vapor lamps produce about 85% of their emissions at a wavelength of 254 nanometers.

This radiation does not directly kill microorganisms, it damages their DNA beyond reproduction.

Failed reproduction lowers the density of airborne mold spores, bacteria and viruses.

There are risks with this technology, which many consumers ignore.

First is Mercury.

Inexpensive UV systems often use thin glass bulbs which will release mercury if broken.

Users should be very careful handling these lamps.

It is also important to avoid touching the glass, grasping the base or ends instead.

There are several user reviews mentioning breaking of these lamps.

If a bulb breaks, debris should be cleaned up and disposed of carefully, and never vacuumed.

UV lamps are not intended to be looked at, the blue light should always stay inside the shielding of the air cleaner.

Many buyers are trying to use these bulbs as replacements in other products, such as toothbrush sanitizers.

People are doing an Amazon search for non-Guardian products with the term "UV Sanitizer bulb" in the string.

These lamps are for the GermGuardian air sanitizers and may not fit other brands or devices.

UV lamps are NOT designed for use outside the product they are built for, and in no case should they be lit where easily damaged eyes can look directly at the "blue" light.

You may be thinking, "Why is he repeating this warning which every sensible person already knows?"

Well, there is one Amazon review where somebody read UV-C "kills bugs" and tried to use a naked UV bulb to try to kill insects.

Fortunately, their brilliant experiment failed to damage insects, which routinely endure direct sunlight, before the rocket scientist could go blind from UV eye damage.

These lamps have few markings and may ship with minimal bubble wrap.

Amazon prices are generally lower.

To be certain you're getting a genuine OEM lamp, shop Sylvane.com or Guardian Technologies.
