Safety is another important factor I kept in mind. UV light can be harmful to the eyes and skin, so I looked for lights that came with protective features or recommended safety gear. I also made sure to read up on any necessary precautions to take while using the light.

Price Range and Budget

As I explored the market, I quickly realized that UV leak detection lights come in various price ranges. I set a budget based on my needs and the features I wanted.
