I bought these new a couple of years ago. The mother website estimates a 10 year life on the led panels and you can buy replacement panels as well as other parts. I drastically reduced my collection and these haven’t been used for around 6 months. Can be used with included stand or you can hang them above your plants. I also used a couple of them in a plant cabinet. In used condition with a few marks and light scratches but in perfect working order and in original packaging.
