Quartz glass 36w

Many people only replace the quartz glass from their UV lamp when it is broken. However, we recommend replacing the quartz glass every 2/3 years. Quartz glass allows less and less UV light to pass through. This can even amount to 25% per year. In addition to replacing quartz glass, you can also clean the quartz glass. However, a clean and clear quartz glass says little about the amount of UV light that it still lets through.
