I'd give it 10 stars if I could. As a wife, I have never purchased a light for my husband of 43 years. But I really wanted to surprise him on our upcoming Anniversary, and buy him a new light. His lights are 20+ years old, and are loud,plus the ballasts get very,very hot. You made it so easy for me to purchase the light , your information about it is great, but the best part was it came with everything needed to use it immediately. Unfortunately I was at the store when it was delivered, and he opened up the box thinking it was the 2 40lb bags of Wild Bird Seed, and 20lb bag of Cat Food I order every month. When I got home ,he had the biggest smile on his face I'd seen in awhile. Then I went to his favorite room,and realized why he was so happy. He loves the new light so much, and now wants a couple more. But he was very impressed with me being able to buy this for him. He doesn't know where I purchased it from, but I definitely will be buying more. Thanks "Grow Ace " , your the best place to shop for grow equipment and supplies.
