I love this light! There are invisible mites that feel like they are biting my legs and feet. I have cleaned with everything to get rid of them, to no avail. I ran across this light which states that it kills mites, mold and germs. I have been using the light for a little over a week and I can tell that the mites have lessen. It is much better. I will continue to use it in the areas that need it. I am hopeful that this light and cleaning with disinfectant will do the trick. It is light weight and a powerful 100 watts. The customer service is terrific. I am so glad I purchased this product. I highly recommend it.
