How Does a UVC Light Bulb Work

9.12.15

UVC Light bulbs generate ultraviolet, UV, radiation within the UVC spectrum for the most powerful germicidal effectiveness.  UVC lamps eliminate bacteria, viruses, mold spores, fungi and harmful contaminants by penetrating the DNA of their cells. UVC radiation destroys the cells of microorganisms making them unable to reproduce, instantly rendering them harmless.

A specially designed UVC light bulb emits UV radiation at precisely 254 nanometer (nm), which delivers the most germicidal effectiveness.  UVC lamps designed to emit energy at 185 nm are used in ozone air purification lamps to effectively eliminate odors from the air including volatile organic compounds (VOCs).  UVC light bulbs provide fresh, clean and odor free air for improved health in many residential and commercial settings.

UVC Light Bulb Specifications

UVC light bulbs are typically low pressure, mercury lamps which provide the optimum amount of UV radiation at the right wavelength. When mercury atoms reach a high energy level, low pressure produces a mercury arc with radiates at exactly 254 nm. UVC lamps usually contain Argon gas or a mixture of Argon, Neon and other gases required in certain applications.  

UVC light bulbs are manufactured similarly to fluorescent lamps, operating with a comparable discharge device.  The body of a UVC lamp is typically made of either:

L Glass – quartz and Titanium which blocks out 185nm

L Glass – soft glass designed to emit 254nm

VH Glass – pure fused quartz that transmits both 185nm and 254nm

UVC lamps do not have the inner phosphor coating which allows for maximum pass through of UV radiation.  UVC bulbs are not designated by voltage as incandescent bulbs are, but rather by operating voltage. The lamp ballasts determine and deliver the operating voltage required to break down rare gases.

People that suffer from psoriasis experience dry, itchy patches of skin in raised, hardened lesions ranging from mild to moderate symptoms.  Conventional treatments such as topical ointments provide relief to some patients with mild to moderate symptoms but are not as effective to people with severe symptoms.

Phototherapy with Ultraviolet (UV) light is proven highly effective at controlling psoriasis symptoms, providing relief to patients suffering with this bothersome skin condition. Phototherapy imitates the sun’s natural healing effects when narrow-band UVB lamps are used for treatment along with lamps combining both UVA and UVB wavelengths.

UV Lamp for Psoriasis Treatment

UV lamp therapy for psoriasis treatment must be administered from a doctor’s office or a medical setting with the correct type of UV phototherapy lamp. Two types of UVB exposure may be prescribed with either narrow band or broad band wavelengths.  The main difference between the two is that the narrow band UVB lamps provide a smaller range of UV exposure.

UVA wavelengths are also used to treat psoriasis although are typically used in combination with psoralen, a medication which increases the skin’s receptiveness to the UV wavelengths. This UV treatment with psoralen is called PUVA, which slows down the excessive growth of skins cells providing effective treatment.  Consistency is key to seeing results which may be visible in a few weeks to months.

Make Sure Your Ballast Water Treatment System is USCG Approved

post 110

The Ballast Water Treatment Convention is what governs the responsibility of the shipping industry, specifically how ships traveling through international waters treat their ballast water. The Ballast Water Treatment Convention (BWTC) established new standards effective September 2017 to address this issue which is considered one of the greatest threats to our planet’s oceans. The BWTC is enforced by the Marine Environment Protection Committee (MEPC), a subsidiary of the International Maritime Organization (IMO).

According to the most recent BWTC, all ships must be equipped with an effective ballast water treatment system that is approved by the United States Coast Guard (USCG).

The Threat of Ships’ Ballast Water

When ships sail through international waters they hold ocean water in their ballast for balance depending on the weight of their cargo.  When delivering cargo in a foreign port, they will take on ballast water to compensate for the loss of weight and provide balance when sailing to their next destination.  When picking up cargo in one port, they may release their ballast water to allow for the additional weight.

By releasing oceanic water into a foreign port, the ships’ ballast water also releases aquatic organisms which invade the foreign port, often with catastrophic consequences. Lifeforms such as mussels, clams, jellyfish, crabs, and many microorganisms including viruses and bacteria which are naked to the human eye invade foreign waters without the safeguard of their natural predators from their home environment. This allows the invading species to multiply, jeopardizing the health and wellness of fish and aquatic lifeforms and even threatens the health of human life inland.

Invading foreign mussels have nearly shut down dams and power plants when allowed to multiply uncontrollably, causing a great risk to the people living in these areas. Jellyfish have been known to destroy fishing industries when invading foreign ports and without their natural predators can be nearly impossible to eradicate.

There is no question that the terms of the new BWTC are established to protect the environment, the sustainability of our world’s oceans and the people that live near these ports that depend upon the fishing industry for their livelihood.
