High Transmission Quartz Tube Firstly, quartz glass is a special type of glass material that has excellent transparency and high-temperature resistance. This allows it to effectively transmit ultraviolet (UV) light, so using quartz glass ensures that the UV light can fully take effect. Secondly, quartz glass has a low absorption rate and radiation ability, meaning it can maximize the range that UV radiation can reach. Additionally, quartz glass also has high corrosion resistance and can withstand the attack of most chemicals and solvents. This is important for the long-term use of sterilization lamps. Chemical-Free Chemical-free: UV filters can kill bacteria, viruses, and other harmful microorganisms through physical means without the use of chemicals. Efficient sterilization: UV filters can efficiently eliminate bacteria and viruses, even tackling microorganisms that may be difficult for chemical filters to address. This ensures clean and hygienic pond water. No secondary pollution: Chemicals can sometimes produce by-products or secondary pollutants that may have negative effects on health and the environment. UV filters, on the other hand, do not require the addition of any chemicals, thus avoiding these issues. 8000 Hours Service Life First, quartz glass has a high melting point, which allows it to withstand the intense heat generated by the UV lamp without deforming or melting. Second, quartz glass is highly resistant to chemical corrosion and degradation, and this helps maintain the integrity of the lamp over time. Additionally, quartz glass has low thermal expansion and excellent thermal shock resistance, which means it can handle rapid temperature changes without cracking or breaking. This property contributes to the durability and longevity of UV lamps made with quartz glass. High Intensity UV UV light has strong germicidal properties and can effectively eliminate bacteria, viruses, and other microorganisms in the water. This helps improve water quality and reduces the risk of diseases in fish and aquatic animals. High-intensity UV light can break down and oxidize organic substances, ammonia nitrogen, and other pollutants in the water, effectively improving water quality and transparency. This creates a clear and healthy water environment, promoting better growth for fish and aquatic plants. Algae prevention: UV light can disrupt the growth and reproduction of algae cells, reducing the overall algae population in the water. 9W 13W 18W 24W 36W 5W Add to Cart Add to Cart Add to Cart Add to Cart Add to Cart Add to Cart Customer Reviews 4.5 out of 5 stars 140 4.4 out of 5 stars 125 4.5 out of 5 stars 45 4.4 out of 5 stars 9 3.8 out of 5 stars 35 4.4 out of 5 stars 33 Price $16.99$16.99 $19.99$19.99 $22.58$22.58 $23.99$23.99 $23.99$23.99 $11.99$11.99 Wattage 9W 13W 18W 18W 36W 5W Base G23 G23 2G11 2G11 2G11 G23 Count 2 Pack 2 Pack 2 Pack 2 Pack 2 Pack 2 Pack
