I think it made s huge difference. Since I made that change the plants have really grown in loads. I think it was $28 shipped and another $5 for the cord I bought at Lowe's. It comes bare wire requiring a plug but there are instructions and it was simple really. The stand was made from some IKEA hardware and cost nothing. It is actually a track for their curtain system with one of the brackets for the same. The claim by the seller is that it is a 7000k 10W LED.. the plants like it.
