I bought several led grow lights from this company as they were suppose to last for at least 50000 hrs. That should equate to about 6 yrs if lights were on 24 hrs a day everyday which is not the case. In less than 1 year I had burn out bulbs on every lamp. They said they would repair them but the cost to return them will be about $800. I would not advise buying these lights from this company.
