Sterilizing units (cosmetic sterilization).Medical devices (phototherapy, drug discovery, protein analysis).So, UV LED lamps are helpful in the following applications: But the UV-A stands out-amongst the three UV-LEDs. UV LED lights are useful in different applications. Plus, it has a short lifespan, and it doesn't work with low power.Īsides from the wavelength ranges listed above, other wavelength LEDs like 405 nm, 365 nm, and 310 nm are available. Regardless of the UV-B LED strength, it has a limitation with sterilizing and inactivating viruses.

Hence, it can cause skin cancer and sunburn. Considering the wavelength of UV-B, it's stronger than UV-A.
The UV-B LED strip or fluorescent backlight has a wavelength of (280-315 nm). Also, UV-A LED has a limited sterilization potential. The UV-A LED strip is useful for lithography, printing, sensing, medical applications, curing, etc. Even though UV-A LED radiation is the weakest, it could be harmful under excessive exposure. So, it means the UV-A LED strip has lower energy. This strip has the highest range of wavelength (315-400 nm). This step is necessary to avoid false claims that will put you at risk-especially for sterilization. So, before you jump at any UV-C LED, double-check the accuracy of its specifications. How long do you plan on sterilizing the area? The answer will help you get the right UV-C LED to achieve the best results. It's essential to ensure that you have sufficient power to affect pathogens. That way, you'll easily focus the light on your target. If you want to be most efficient with a powerful UV-C LED, it's ideal to choose optics that would help. Then, be clear about how close in proximity you need. You have to be particular about the area you intend to sterilize. But, to achieve success with the UV-C LED, it would be best to consider factors like: In summary, the UV-C LED has a high sterilization potential. But, when the wavelength is above or longer than 300 nm, absorption of the nucleic acid is almost impossible. Uracil and Thymine (the genetic makeup of the RNA and DNA, respectively) are quite sensitive at wavelengths of 250 nm or closer to 265 nm. Moreover, the UV-C attacks the DNA and RNA of microscopic organisms and pathogens. And it can kill pathogens like viruses, mold, bacteria, etc., on surfaces, air, or water. UV-C LED is the most powerful amongst the other types of strips. And they all have different wavelengths and effectiveness. Now, you have an idea of UV LED lights, let's dive into the types. Also, it's ideal to avoid low-cost strips that claim high brightness. While you're at it, avoid UV LED strips without a brightness specification in lumens.
