Germicidal Lamps

UV germicidal lamps are used for a wide range of sanitising applications, such as sterilising tools, laboratories, medical facilities, hot tubs, aquariums, and in the treatment of wastewater, to name just a few.

A germicidal lamp emits ultraviolet (UV-C) light, which is a known disinfectant for air, water, and surfaces that can help mitigate the risk of acquiring an infection. This makes it a highly effective and environmentally friendly disinfection solution, which does not involve the use of harmful chemicals. 

There is a wide range of germicidal lamps available, suitable for many different applications. We supply Philips and Osram germicidal ultraviolet lamps, both of which have a strong reputation for producing high-quality products, utilising cutting-edge technology. They provide almost constant UV output over the useful lifetime of the lamp – ideal for highly effective sterilisation and purification.

How Do Germicidal Lamp Work?

UV-C radiation is germicidal, which means it deactivates the DNA of bacteria, viruses, and other pathogens, destroying their ability to multiply. More specifically, UV lamps cause damage to the nucleic acid of microorganisms by forming covalent bonds between certain adjacent bases in the DNA. When these bonds form, the organism is incapable of reproducing – In fact when the organism does try to replicate, it dies.

FAQs Germicidal UV Lamps

What Is a Germicidal Lamp?

A germicidal lamp is a type of electric light that produces ultraviolet (or UVC) that works to kill bacteria, viruses and protozoa on exposed surfaces.

Germicidal lamps create short-wave UV light that disturbs DNA base pairing and thus prevents further multiplication. These lamps remove and reduce the risk of infection, explaining their use for disinfectant purposes.

How Long Does a Germicidal Lamp Last?

Germicidal ultraviolet lamps have a useful life of between 5000 and 9000 hrs which is approximately 6 to 12 months. This will vary depending on the installation/use and also the average lamp life quoted by the manufacturer.

After this time, the amount of useful UV-C light will decrease even though the lamp may still be providing light. It is essential that your UV lamp is changed at this time to ensure maximum security of disinfection in your system.

If you are unsure when to replace your UV Lamp, contact ELC Lamps for more information.

Are Germicidal UV Lamps Safe?

Direct exposure to UV-C light can cause eye injuries and burns to the skin. You should never look directly into a UV-C lamp source. Typically, injury risk is more significant when a UV system has not been installed correctly or is being used by an untrained person.

Additionally, some UV-C lamps generate Ozone which can cause irritation to the airways. 

What are Germicidal Lamps Used for?

Germicidal lamps are used for air purification, water disinfection and sterilizing hard surfaces. They emit high-intensity UV-C Light which kills 99.9% of bacteria, viruses and other harmful pathogens.  Research has shown that UV-C light can effectively kill SARS-CoV-2 or other coronaviruses in liquids, in the air and on surfaces. 

How Does a Germicidal Lamp Work?

Microorganisms reproduce through a process called binary fission, where a single bacterium will replicate both its internal and exterior parts, with the cell eventually splitting into two.

A germicidal lamp works by deactivating the DNA of bacteria, viruses and protozoa that reside on surfaces, in water or in food. The UV light emitted from these lamps is absorbed and their ability to multiply is destroyed, removing the risks posed by pathogens. 

What our customers have to say…

“Ordered a UV lamp at 3.45 pm it arrived in Aberdeenshire next morning. The cost of the item was a fraction of what was on offer elsewhere. A technical query was answered by phone in a friendly and efficient manner.

I will most certainly be using this company again and would recommend it to anyone else.”


“I purchased a UV lamp from ELC. The price was great, delivery was superfast (next day) and the bulb was really well packaged so it arrived safely.
I’ll definitely be ordering from you again, thank you.”

“We cannot believe how fast our order arrived!!! Ordered a lighting bulb on Friday afternoon and it arrived Saturday morning in NE Scotland. We used this company after a long search for the UV bulb we needed and will file your details for the future. Thank you so much for an amazingly prompt service.”
